Josh: So Anthropic just released a brand new model. It's not the best model. (00:00):
undefined

Josh: It's not the smartest model. (00:03):
undefined

Josh: It's not the cheapest or the fastest model. And yet this is possibly our most (00:04):
undefined

Josh: favorite model release this entire year. (00:09):
undefined

Josh: So what gives here? What's actually happening with Claude Opus 5? (00:11):
undefined

Josh: This is the new iteration after Opus 4.8 and it sits just under Claude Fable 5. (00:15):
undefined

Josh: Now a lot of people see this, they're like, hmm, I'm not that excited about (00:19):
undefined

Josh: this model. It's just an iteration on another model that we've already had. (00:22):
undefined

Josh: I think you're wrong. And I have some demos here. Ejaz, I know you've been playing (00:26):
undefined

Josh: with this since the weekend, basically, talking to Opus 5, figuring out where (00:30):
undefined

Josh: the edge cases are, figuring out how all of this works. (00:35):
undefined

Josh: And the review so far is pretty great, right? Like Opus is a really fun model. (00:38):
undefined

Josh: And I think that's what we're going to spend this episode unpacking, (00:42):
undefined

Josh: is just how fun it is and how to get the best out of this model if you are someone (00:44):
undefined

Josh: who's new coming to Opus 5.0. (00:48):
undefined

Ejaaz: First and foremost, this model, as you mentioned, is not the cheapest, (00:50):
undefined

Ejaaz: but it's as cheap as Opus 4.8. (00:54):
undefined

Ejaaz: But it's a massively different type of model. And the first characteristic that (00:57):
undefined

Ejaaz: it's very good at is visual intelligence. (01:00):
undefined

Ejaaz: So what I mean by this is no clawed models can actually kind of see things. (01:03):
undefined

Ejaaz: It kind of like when you send it an image, it kind of breaks down the pixels (01:07):
undefined

Ejaaz: and reinvents what it's looking at from a code perspective. (01:11):
undefined

Ejaaz: Now, what I'm about to show you on my screen, Josh, was one-shotted over one and a half hours, okay? (01:14):
undefined

Ejaaz: It guzzled around 150,000 tokens. (01:20):
undefined

Ejaaz: I didn't click anything after I sent the prompt and all of this is one shot. Are you ready? (01:24):
undefined

Ejaaz: Let me tell you if you, let me ask you if you recognize what you're looking at right now. (01:30):
undefined

Josh: Oh my goodness, this looks like home. I'm seeing the Williamsburg Bridge. (01:34):
undefined

Josh: Oh my God, this is the East River. (01:37):
undefined

Josh: Do you see this, Pat Boy? Oh, wait, dude, this looks awesome. (01:40):
undefined

Ejaaz: This is a structurally accurate, of course, graphically rendered version of (01:44):
undefined

Ejaaz: the Brooklyn Bridge live with trucks at sunset. (01:50):
undefined

Ejaaz: All I said to Claude was, I want you to recreate the Brooklyn Bridge, (01:54):
undefined

Ejaaz: dimensionally accurate, pull the architectural renderings, everything on your own. (01:59):
undefined

Ejaaz: And then I want you to span out a bunch of sub agents. (02:05):
undefined

Ejaaz: And I want you to get these agents to build different components of the Brooklyn (02:09):
undefined

Ejaaz: Bridge and then review it. (02:13):
undefined

Ejaaz: So take a screenshot, review it, and only feed me back the end result once you (02:15):
undefined

Ejaaz: are satisfied with it. But it needs to look like something out of a really cool computer game. (02:20):
undefined

Ejaaz: And this is what we ended up with. Here, let me show you the sunset that wide (02:26):
undefined

Ejaaz: shot, if you want to have a look. (02:29):
undefined

Ejaaz: Let me show you a tower over here. (02:30):
undefined

Josh: Oh, that's fun. Okay, so it is pre-made shots for it as well. (02:32):
undefined

Ejaaz: Yeah, maybe I'll show you the promenade if you notice the bridge is swaying, (02:35):
undefined

Ejaaz: but maybe you want to look underneath the deck, make sure it's all structurally sound. (02:38):
undefined

Ejaaz: Now, imagine the different use cases for this. Obviously, there's simulations, (02:42):
undefined

Ejaaz: there's games, but if you're an architect that is coming up with a brand new (02:45):
undefined

Ejaaz: idea and you want to kind of put things out in the wild, you can now have a (02:49):
undefined

Ejaaz: physically and structurally accurate rendering of this model. (02:53):
undefined

Ejaaz: Now, I know a lot of folks listening to this might be thinking, (02:56):
undefined

Ejaaz: well, okay, maybe I don't want to be creating games and stuff like that. (02:58):
undefined

Ejaaz: We'll get to the other good stuff. But what I want to point out is cold Opus (03:01):
undefined

Ejaaz: can't see anything. I just want to reiterate that. (03:05):
undefined

Ejaaz: It generated every single asset, every single visual that you're seeing on screen (03:07):
undefined

Ejaaz: right now from scratch. It created a file on my computer. (03:11):
undefined

Ejaaz: It did so with one single prompt in one and a half hours, and it only cost 100,000 (03:15):
undefined

Ejaaz: tokens. It's so, so impressive. (03:19):
undefined

Josh: I think this is the thing that Opus 5 is really exceptional at that a lot of (03:21):
undefined

Josh: people are figuring out is when we went to Fable we always loved the visual demos. (03:25):
undefined

Josh: Fable was excellent but it's incredibly expensive. It takes a long time. (03:28):
undefined

Josh: It is that leading flagship model if you want the best. Opus 5 gives you (03:32):
undefined

Josh: Almost all of that, but with a fraction of the cost, a fraction of the time, (03:36):
undefined

Josh: and other really unique capabilities. So we have a few other demos, (03:40):
undefined

Josh: some that we found online that we didn't make ourselves. (03:43):
undefined

Josh: And they blew my mind with the first one being this video that we're seeing (03:45):
undefined

Josh: now. So this guy on X, he said he one-shotted this game. (03:49):
undefined

Josh: And this game is a demo made of custom code without a single external asset. (03:54):
undefined

Josh: And when you look at this game, it looks like you're watching a game of Call of Duty. (03:59):
undefined

Josh: It's really impressive. This is Call of Duty. It's what it looks like, (04:02):
undefined

Josh: right? I mean, the hands are a little funny and like there's definitely a lot of weird quirks here. (04:05):
undefined

Josh: But for a one shot prompt on a model that is not a flagship model, (04:08):
undefined

Josh: this is incredibly impressive. (04:12):
undefined

Josh: And what I really appreciated about this model and what we're going to do right (04:14):
undefined

Josh: now for the people who are watching is you could actually go and play this model (04:17):
undefined

Josh: right now in the browser. (04:20):
undefined

Josh: So please, if you would, I have the browser and let's see what your skills are (04:21):
undefined

Josh: like. Now, for people who don't know, I've spent my entire life playing Call (04:26):
undefined

Josh: of Duty, very familiar with the game. (04:29):
undefined

Josh: And I'm here to criticize Ejaz on how well you are able to play this one-shot (04:31):
undefined

Josh: demo from Opus 5. And we have the game loaded up here, Ejaz. Let's see what you got. (04:36):
undefined

Josh: It's funny, this looks like a map from Call of Duty Modern Warfare. (04:40):
undefined

Josh: I could see you're getting kills, you know, reasonably well. (04:43):
undefined

Ejaaz: Oh my God, I'm getting cooked. (04:45):
undefined

Josh: Honestly, of all the players, if I had to team up with, I'm not sure you're (04:47):
undefined

Josh: going to be the one for Call of Duty. (04:51):
undefined

Josh: I got to be honest with you, I'm not super impressed with the movement or the shots. (04:53):
undefined

Josh: Fair enough. But this is like a really impressive demo. I mean, (04:56):
undefined

Josh: the fact that this was created with one shot on opus 5 this is a game that costs (04:58):
undefined

Josh: studios billions of dollars to develop and you have a lot of the textures like (05:03):
undefined

Josh: the textures of the map look good (05:06):
undefined

Josh: the design of the weapon looks good the hands are a little funky but it has (05:08):
undefined

Josh: the skybox it has all these things (05:12):
undefined

Josh: that you would look for if we had audio turned on you can actually hear (05:13):
undefined

Josh: the sound of footsteps you can hear the hit boxes when someone gets hit by a (05:16):
undefined

Josh: bullet you can hear the weapon firing it's really robust and it clearly has (05:19):
undefined

Josh: this very deep understanding of what these games look like and that's what i (05:23):
undefined

Josh: found and super interesting with this particular demo. (05:26):
undefined

Josh: We have a couple other demos that I wanted to show before we got too deep into this. (05:28):
undefined

Josh: One of which being a snowboarder game. So one of my favorite video games when (05:32):
undefined

Josh: I was younger, SSX Tricky. (05:36):
undefined

Josh: I'm not sure you've ever played that, Ejaz. It is a snowboarding game where (05:37):
undefined

Josh: you go down a slope and you do tricks and you get points for doing these crazy tricks. (05:41):
undefined

Josh: There is another one just like that. It doesn't have the tricks per se, (05:46):
undefined

Josh: but it is a snowboard game indistinguishable from a game like SSX Tricky. (05:49):
undefined

Josh: In fact, far more impressive in terms of visual integrity than a game like SSX (05:53):
undefined

Josh: Tricky would be. And there's a quote post that Signal wrote. (05:59):
undefined

Josh: I always love reading Signal's post on X. (06:02):
undefined

Josh: And he had some commentary about this specifically. And he says, (06:04):
undefined

Josh: if you put this game in the App Store in 2012, it would have potentially grossed (06:07):
undefined

Josh: $5 to $10 million, at least over its lifespan, maybe even more. (06:11):
undefined

Josh: Today, it can be one-shotted by roughly anyone with the correct physics, (06:15):
undefined

Josh: graphics, gameplay, etc. (06:18):
undefined

Josh: It's like $10 million of economic value wiped out in 15 years on only one game. (06:20):
undefined

Josh: And I think that's kind of true. It's very impressive that we're able to get (06:25):
undefined

Josh: things indistinguishable from leading AAA games from a single prompt on a model (06:28):
undefined

Josh: that isn't even Frontier. And that's kind of the essence of Opus 5 as we've (06:33):
undefined

Josh: been playing it. It's like the best (06:38):
undefined

Josh: bang for your buck as it relates to getting high quality tokens for what you're able to pay for them. (06:40):
undefined

Ejaaz: Before we go into what else Opus 5 is good at, and trust me, (06:45):
undefined

Ejaaz: there are many things, I just want to talk about what it takes to create something (06:49):
undefined

Ejaaz: that is as compelling visually as what you're seeing on screen as the games (06:53):
undefined

Ejaaz: that we've showed you in one shot. (06:57):
undefined

Ejaaz: Like, I am not exaggerating. I will show you the prompt that Matt Schumer used (06:58):
undefined

Ejaaz: to create that FBS game that we just played badly. (07:02):
undefined

Ejaaz: He goes, I want you to build a first person shooter at the level of the most (07:06):
undefined

Ejaaz: recent Call of Duty games, it should be utterly perfect, visually beautiful, (07:09):
undefined

Ejaaz: with every single thing done at AAA quality, from textures to physics to anything you can think of. (07:13):
undefined

Ejaaz: Then he goes on to say, and this is the key part, so if you're listening to (07:19):
undefined

Ejaaz: this and you're wondering, how can I do this for a game or for any other task (07:22):
undefined

Ejaaz: that you're trying to do using your AI model, he says the following, (07:25):
undefined

Ejaaz: fan out sub-agents and have sub-agents tackle each one individually so that (07:29):
undefined

Ejaaz: the game is utterly perfect. (07:34):
undefined

Ejaaz: You should slash loop on each item and have a separate sub-agent check it visually (07:35):
undefined

Ejaaz: to ensure it looks AAA. That separate sub-agent should be a really harsh critic. (07:41):
undefined

Ejaaz: And if it doesn't look AAA, it should keep going. (07:45):
undefined

Ejaaz: Now, let me unpack why that's so important for not just this gaming prompt, (07:48):
undefined

Ejaaz: but any prompt that you do for whatever you're trying to build using AI. (07:51):
undefined

Ejaaz: He, number one, said, spin up multiple versions of yourself, (07:55):
undefined

Ejaaz: Claude, so that you can work separately at the same time on different components of product. (07:59):
undefined

Ejaaz: Now, if you think about a traditional company, they hire a ton of employees (08:05):
undefined

Ejaaz: and they have different teams that all work together to build the same product. (08:08):
undefined

Ejaaz: In this instance, it's the same thing, except there are various versions of (08:11):
undefined

Ejaaz: Claude that tackle different tasks. (08:15):
undefined

Ejaaz: Number two, he asked it specifically to spin up a manager role, (08:17):
undefined

Ejaaz: which basically monitors these agents that are building these different things (08:21):
undefined

Ejaaz: to make sure that they do a good job. (08:24):
undefined

Ejaaz: And then number three, he said, use this loop function. The loop function is (08:25):
undefined

Ejaaz: basically, hey, if you're not happy with the work that you just created, (08:29):
undefined

Ejaaz: don't give it to me to give you feedback and say like, hey, improve this. (08:33):
undefined

Ejaaz: Just use another agent to do this. And this beautiful. (08:36):
undefined

Ejaaz: Kind of synonymous loop can be applied to anything, not just a game. (08:40):
undefined

Ejaaz: It could be applied to your Excel tasks that you're trying to do at work. (08:43):
undefined

Ejaaz: It could be applied to a blueprint that you're trying to create your architecture (08:46):
undefined

Ejaaz: from. It could be applied to anything. (08:50):
undefined

Ejaaz: And I think this is a really valuable lesson to figure out with Opus 5 specifically, (08:51):
undefined

Ejaaz: is that you can spin up multiple agents and create something really, really awesome. (08:56):
undefined

Ejaaz: But Josh, I think kind of moving on from the visual aesthetics of what Claude (09:00):
undefined

Ejaaz: Opus 5 can do, it made some pretty major breakthroughs in some other things, (09:04):
undefined

Ejaaz: including something called Arc AGI 3, which is basically the precipice of any AI model test. (09:09):
undefined

Josh: Yes, Arc AGI 3 is like the flagship test. And when it comes to this flagship (09:15):
undefined

Josh: test, Opus has done exceptionally well. (09:20):
undefined

Josh: The previous high score was 7.8, scored by GPT 5.6 Sol Max, the highest end (09:23):
undefined

Josh: GPT model that's currently available. Opus 5 got a 30%. (09:30):
undefined

Josh: I mean, that's like an unbelievably high amount of rating on this benchmark (09:33):
undefined

Josh: and we have to ask the question why what did it do and (09:38):
undefined

Josh: arc actually came out and explained themselves and they said during our analysis (09:42):
undefined

Josh: of opus 5 we observed a new capability previously unseen from frontier models (09:45):
undefined

Josh: opus 5 used advanced logical reasoning to turn arc agi 3 layouts into algebraic notation (09:50):
undefined

Josh: on action 23 it describes the seen as four center equal two axis five center (09:56):
undefined

Josh: basically what it's doing here is instead of taking the visuals you just like (10:01):
undefined

Josh: you mentioned opus can't see (10:05):
undefined

Josh: it takes the visuals converts them into math and then thinks on that math that it's (10:07):
undefined

Josh: visualizing and as a result it's able to achieve significantly better scores (10:12):
undefined

Josh: on this visual reasoning (10:16):
undefined

Josh: logical reasoning i guess is how they describe it versus other models so i find (10:17):
undefined

Josh: this really interesting if you look at the example on screen that they were (10:21):
undefined

Josh: showing if we could just go back to just the general demo it shows these shapes that are shifting (10:24):
undefined

Josh: and a lot of times models have difficulty (10:29):
undefined

Josh: Applying logic to make these work. Opus, because they converted it all to math, (10:32):
undefined

Josh: it was able to achieve such a high score. It was really impressive. (10:36):
undefined

Josh: This is what, four or five times that of the next leading model? (10:38):
undefined

Josh: And cost, I know for a fact, this cost a fraction of what it costs for 5.6 Sol max. (10:42):
undefined

Josh: So really impressive outputs from this thing. (10:47):
undefined

Ejaaz: If we compare this directly with Fable, it can do most of the things that Fable (10:49):
undefined

Ejaaz: is capable of, but at a fraction of the cost, specifically 50% less cost. (10:54):
undefined

Ejaaz: Now, it can't do some things that Fable is really good at, such as extreme reasoning (10:59):
undefined

Ejaaz: or coding at the highest level. (11:05):
undefined

Ejaaz: But as a workhorse model, it is exceptionally intelligent. (11:07):
undefined

Ejaaz: And it's now my default versus Opus 4.8. But let's look at some of the examples (11:11):
undefined

Ejaaz: as to like cost wise and what this shapes up in other kinds of benchmarks. (11:16):
undefined

Ejaaz: So with Fable 5, it's kind of on average better than Fable 5 when it comes to computer use. (11:20):
undefined

Ejaaz: The price ends. So you're paying around, I think it's $5 per million tokens (11:26):
undefined

Ejaaz: input and $25 per million tokens output. So $30 overall, if you want to kind (11:30):
undefined

Ejaaz: of use this for usage credits, that is exactly half the cost of Fable, (11:35):
undefined

Ejaaz: but you're getting so much more. (11:38):
undefined

Ejaaz: And then the other thing I'll say is my biggest critique for Fable, (11:40):
undefined

Ejaaz: Josh, is that whenever I'm trying to use it for pretty much most things, (11:44):
undefined

Ejaaz: it sometimes gets triggered or rather frequently gets triggered through its safety flag. (11:49):
undefined

Ejaaz: So it gets relegated to Opus 4.8. (11:53):
undefined

Ejaaz: With Opus 5, I haven't come across that at all. (11:56):
undefined

Ejaaz: When I ask it to do something, even if it's bio-related or cybersecurity-related, (12:00):
undefined

Ejaaz: like if I'm saying, hey, can you check my computer for bugs and make sure that it's all good? (12:03):
undefined

Ejaaz: It just does the thing. And that's the other thing about Opus 5. (12:07):
undefined

Ejaaz: It is almost as intelligent as Fable 5 when it comes to biology and cybersecurity-type (12:11):
undefined

Ejaaz: things, but it's really hard to exploit. (12:17):
undefined

Ejaaz: If you try to prompt inject it, it is an extremely aligned model, (12:21):
undefined

Ejaaz: which just won't do the thing. It's smart enough to understand when you're asking (12:25):
undefined

Ejaaz: an innocent question about research (12:29):
undefined

Ejaaz: or whatever that might be without triggering any safeguards. It is, (12:30):
undefined

Ejaaz: arguably the perfect version of fable five and it's going to be my go-to model going forwards. (12:34):
undefined

Josh: Yeah i love this model and there's interesting ways in which you can use it (12:39):
undefined

Josh: and it feels like it's the perfect (12:43):
undefined

Josh: completion to this family of five class models from anthropic i mean when you think about it (12:45):
undefined

Josh: anthropic released four frontier models in eight weeks we're getting now one (12:50):
undefined

Josh: every other week we have mythos five fable five sonnet five now so we have the (12:53):
undefined

Josh: this top three that's kind of sitting here this rounds out the set and this is the perfect fallback (12:58):
undefined

Josh: from fable and it feels like that, where when, (13:02):
undefined

Josh: as I've been testing it, as I've been using this, I found the most success with (13:05):
undefined

Josh: really hard problems using Fable. (13:09):
undefined

Josh: Fable will think for a very long time. And the longer I think, (13:11):
undefined

Josh: the better the outputs generally are. (13:13):
undefined

Josh: I find that Fable is very ambitious. It will go off. It will spin out its own subagents on its own. (13:16):
undefined

Josh: It will think very critically. It will develop plans and then check against (13:21):
undefined

Josh: those plans and do so in a way that I can trust. (13:24):
undefined

Josh: And I know that the longer it's running, the better my result will be. (13:27):
undefined

Josh: Opus, I will say, is a little bit different. It's a great fallback in the sense (13:30):
undefined

Josh: that if Fable gets tripped up with security or bioweapon, I'm so glad that it (13:34):
undefined

Josh: now lands on Opus 5 instead of 4.8. It's much more capable. (13:38):
undefined

Josh: But I think it's different. As you mentioned that it's a workhorse model, (13:41):
undefined

Josh: it feels like a workhorse model. It's great for shorter duration tasks. (13:44):
undefined

Josh: And I would, generally speaking, if you're using Fable, if you're using Opus, (13:48):
undefined

Josh: I would delegate it to those smaller tasks. In fact, during testing, (13:52):
undefined

Josh: one of my favorite modes to use it on is medium instead of high or extra high. (13:56):
undefined

Josh: Because what I find is the longer Opus thinks the kind of more tripped up it (14:00):
undefined

Josh: can get it feels like the little brother that was trained by fable so it knows (14:04):
undefined

Josh: to think like fable but it doesn't quite understand the reasoning behind why fable does everything (14:08):
undefined

Josh: and that unlock does make the outputs feel a little messy sometimes over really (14:14):
undefined

Josh: long duration tasks so if you're someone who's using this (14:18):
undefined

Josh: Try medium and see how medium effort performs. It's not necessarily a worse (14:21):
undefined

Josh: output. It just thinks for a little bit less longer. (14:25):
undefined

Josh: And if it has less time to kind of think and turn into these thought spirals, (14:27):
undefined

Josh: you might wind up getting slightly better outputs. That's how I've been using it. (14:31):
undefined

Josh: For the people who are wondering how to use this, I believe the free plan has (14:34):
undefined

Josh: access to it, but also the $20 a month plan gives you quite a bit of access (14:37):
undefined

Josh: to Opus 5, which seems very worthwhile for the amount of output tokens that (14:41):
undefined

Josh: you can get from this thing. (14:45):
undefined

Josh: And if you did want fable that does require i think the hundred dollar max plan (14:46):
undefined

Josh: but also i know they're giving out a hundred dollars in usage tokens to test (14:49):
undefined

Josh: this out to a lot of accounts so there is the option for everyone to kind of get involved (14:53):
undefined

Josh: and try this out but for twenty dollars a month man this is a really compelling (14:56):
undefined

Josh: model to do some like serious damage on any workloads that you might have (15:00):
undefined

Ejaaz: It's my new go-to model and if if you're wondering hmm should i switch to gpt 5.6 sol (15:04):
undefined

Ejaaz: which model should be my everyday model you should basically use this model (15:10):
undefined

Ejaaz: that that would be my kind of like bit of advice here because it's really good (15:14):
undefined

Ejaaz: at just general reasoning and answering most general questions that people have. (15:18):
undefined

Ejaaz: Now, what it's not exceptional as, I think it's worth pointing out, (15:21):
undefined

Ejaaz: is if you want the best-in-class model for coding or to reference different (15:25):
undefined

Ejaaz: types of health or, in some cases, some kind of cybersecurity e-bals, (15:30):
undefined

Ejaaz: you are still better off using. (15:35):
undefined

Ejaaz: Fable or if you are one of the classified partners from Anthropic, Mythos 5. (15:37):
undefined

Ejaaz: But as a general model, it is a fantastic thing to get access to. (15:41):
undefined

Ejaaz: The other thing I'll say is, I think this is the first ever model launch from (15:45):
undefined

Ejaaz: Anthropoc or any Frontier Lab, where they didn't advertise. (15:50):
undefined

Ejaaz: How intelligent it is. You mentioned ARC AGI 3 earlier, Josh. (15:54):
undefined

Ejaaz: Now, if you've heard of the AGI index or the test, there was AGI 1 and AGI 2. (15:58):
undefined

Ejaaz: But the issue was all these models kept getting smarter and just beating these tests to 100%. (16:03):
undefined

Ejaaz: They had to start creating more difficult, hard-to-solve benchmarks. (16:08):
undefined

Ejaaz: And ARC AGI 3 was the most recent one. And as you mentioned, (16:12):
undefined

Ejaaz: the most recent model, GPT 5.6 SOL, scored 7%. This one scored 30%, (16:15):
undefined

Ejaaz: the highest of any model higher than Fable, but this wasn't the headline advertisement from Anthropic. (16:19):
undefined

Ejaaz: And I think a reason behind that might potentially be, you know, (16:26):
undefined

Ejaaz: they don't really want to advertise how intelligent these models are because (16:29):
undefined

Ejaaz: of fear of regulation or whatever that might be. (16:32):
undefined

Ejaaz: But the point is, if you don't have access, if you don't have one of those memberships (16:34):
undefined

Ejaaz: that Josh just mentioned to get access to Fable 5, fear not, (16:37):
undefined

Ejaaz: because Opus 5 itself is actually a fantastic model in itself. (16:41):
undefined

Ejaaz: And I encourage you to go out and try this. Now, the other part that I will (16:44):
undefined

Ejaaz: say is really powerful, what makes this model like really valuable to use is (16:48):
undefined

Ejaaz: the fact that it can natively spin out multiple AI agents to go and do your task. (16:52):
undefined

Ejaaz: And this cannot be understated because usually when people interact with an (16:58):
undefined

Ejaaz: AI model, they just have a one-on-one conversation with one instance of Claude. (17:02):
undefined

Ejaaz: But imagine if you could have a one-on-one conversation with Claude and it spins (17:05):
undefined

Ejaaz: out a hundred different employee workers to go and do your job and it works (17:10):
undefined

Ejaaz: in parallel simultaneously. AI agents is without doubt the future of how you execute work. (17:13):
undefined

Ejaaz: And it's incredibly important to focus on their security. (17:19):
undefined

Josh: And speaking of agents and just all the sub-agents that Opus can spin up, (17:21):
undefined

Josh: we have a sponsor that is here to talk about agents and they are Ledger. (17:25):
undefined

Josh: If you are building with AI agents, you're worried about security. (17:29):
undefined

Josh: An agent with unchecked access is a brilliant but probabilistic teammate with (17:31):
undefined

Josh: access to important secrets. (17:36):
undefined

Josh: Ledger Agent Stack fixes that with four open source tools, DMK Skills and CLIs (17:37):
undefined

Josh: for Ledger Wallet, Ledger Enterprise and Ledger Enterprise Multisig that lets (17:41):
undefined

Josh: your agents work with crypto while you stay in control. You can tell your agent, rebalance my wallet. (17:45):
undefined

Josh: ETH to 40%, fastest swaps. It does the math, drafts the swap, and stops. (17:50):
undefined

Josh: The transaction lands on your ledger signer and nothing moves until you approve it. (17:55):
undefined

Josh: Agents Propose, Humans Approve, Ledger Signers Enforce. And this works with (17:58):
undefined

Josh: Cloud Code, Codex, Cursor, it's open source, ready today on developers.ledger.com, (18:03):
undefined

Josh: which you can find in the link in our description below. Thank you so much to (18:08):
undefined

Josh: Ledger for sponsoring this episode. (18:11):
undefined

Josh: And now, speaking of all these safeguards, these approvals, we have to talk (18:13):
undefined

Josh: about where Opus 5 sits on the security spectrum. EJS, I know for a fact that (18:16):
undefined

Josh: if I ask it, how to build me a nuclear warhead, it's not going to answer. (18:21):
undefined

Josh: But there's a line that is closer to there than Fable 5 is. So where is that (18:24):
undefined

Josh: line in terms of what you can use this model for? (18:29):
undefined

Ejaaz: Well, rather than give you the line first, I want to give you a stat, (18:31):
undefined

Ejaaz: which should relieve a lot of people listening to this that have been using Fable. (18:36):
undefined

Ejaaz: 85% of the time, you have fewer stops, so fewer relegations to older models. (18:40):
undefined

Ejaaz: And what that means is, if you ask it a question, let's say it's like, (18:47):
undefined

Ejaaz: you know, can you tell me that the mitochondria is the powerhouse of the cell? (18:50):
undefined

Ejaaz: It won't flag you for trying to be an aggressor. (18:53):
undefined

Ejaaz: It instead just answers your question 85% of the time. (18:56):
undefined

Ejaaz: And this is massive because it's almost, from my experience personally, (19:01):
undefined

Ejaaz: every other attempt that I use Fable 5 for, it gets triggered unless I'm explicitly (19:04):
undefined

Ejaaz: not talking about any kind of AI models. And when you're doing a show where (19:09):
undefined

Ejaaz: you talk about AI models, it's kind of a hard thing to avoid. (19:12):
undefined

Ejaaz: So the level up that's happened with Opus 5 here is they saw the feedback with Fable 5. (19:15):
undefined

Ejaaz: They saw that the safety guards were getting triggered. And for context, (19:20):
undefined

Ejaaz: for anyone that's listening, if you're wondering why these safeguards are in (19:23):
undefined

Ejaaz: place, it's because the US government got involved with Anthropic's release (19:25):
undefined

Ejaaz: of Fable 5 and said, hey, like this thing is too powerful. You need to add more (19:29):
undefined

Ejaaz: safeguards to it. You can't release your Mythos model. (19:32):
undefined

Ejaaz: We need to have a safe version so that people don't exploit it and use it for malicious purposes. (19:35):
undefined

Ejaaz: So Anthropic, pause, put out this Fable 5 model with a lot of safety guards, (19:39):
undefined

Ejaaz: and they've been iterating ever since. Opus 5 is the embellishment of what a (19:43):
undefined

Ejaaz: good version of Mythos 5 looks like to me personally. (19:47):
undefined

Ejaaz: And it's because when it comes to the biggest risk indicators, (19:51):
undefined

Ejaaz: which is when anyone's asking about cybersecurity, they could potentially want (19:55):
undefined

Ejaaz: to exploit another app or platform using that. (19:59):
undefined

Ejaaz: Or if they're evaluating biological types of things and they don't want to make (20:02):
undefined

Ejaaz: sure they create a bioweapon, they can succinctly have a conversation with Opus (20:06):
undefined

Ejaaz: 5 and you can't prompt inject Opus 5 to give you any kind of a malicious answer. (20:11):
undefined

Ejaaz: And this is the main thing. when I was looking at the system card, (20:16):
undefined

Ejaaz: the way, the blueprint of how they created this model, there is a heavy index, (20:18):
undefined

Ejaaz: a heavy framework around Opus 5, which prevents you from trying to get a malicious answer from it. (20:23):
undefined

Ejaaz: Now, can you use it to look at your computing operating system and figure out (20:29):
undefined

Ejaaz: if there are any bugs to fix, (20:33):
undefined

Ejaaz: Yes. But can you ask the Opus model to then create a potential defense to that exploit? (20:35):
undefined

Ejaaz: The answer is no. You need to kind of like go through your own way to build (20:42):
undefined

Ejaaz: it yourself, either by hand or to use it as an assistant. (20:45):
undefined

Ejaaz: But you can't directly ask it to create a fix for it. And that, (20:47):
undefined

Ejaaz: I think, is the most important nuance between the cybersecurity evals, (20:50):
undefined

Ejaaz: the biosecurity evals between Opus 5 and Fable 5. (20:54):
undefined

Josh: I mean, to frame this pretty practically, I've been using this for a while and (20:57):
undefined

Josh: I've been testing all the edge cases and you basically don't notice it. (21:00):
undefined

Josh: I'd say this is about the same safeguard level as standard models in the sense (21:03):
undefined

Josh: that you're not going to run into it unless you are intentionally trying to run into it (21:06):
undefined

Josh: you really got to ask some kind of edgy fringe questions in order to hit those (21:10):
undefined

Josh: safeguards so i would say in terms of what you're actually going to realize (21:13):
undefined

Josh: you are going to get blocked significantly less than you would with fable to (21:18):
undefined

Josh: the point where you don't really notice it (21:20):
undefined

Josh: and i think this is kind of where i've landed as a more power user who is (21:23):
undefined

Josh: i just kind of token hungry just for the fun of it and i love using fable as (21:27):
undefined

Josh: the default but i really appreciate the fact that I can have Opus 5 as that (21:30):
undefined

Josh: fallback that can confidently answer questions that Fable cannot. (21:34):
undefined

Josh: For example, I was trying to figure out stuff about there's this like new breakthrough (21:38):
undefined

Josh: with like genomic sequencing and it'll like diverse the aging of your skin. (21:42):
undefined

Josh: I was like, oh, this is sick. Let me read about it. (21:45):
undefined

Josh: Fable was on the case. It couldn't figure it out. Opus took over. (21:47):
undefined

Josh: It can handle that stuff fine. So in terms of safeguards, this will feel just (21:50):
undefined

Josh: like an unfiltered model. This will give you the outputs that you want. (21:53):
undefined

Josh: It's a lot less kind of on a hair trigger when it comes to these safeguards. (21:56):
undefined

Josh: And that makes it a really fun model to use. So it's amazing. (22:01):
undefined

Josh: It is accessible to everyone. (22:04):
undefined

Josh: I will say that the one thing that you could caveat it with is the long duration thinking. (22:05):
undefined

Josh: Sometimes it gets a little bit confused. So you may want to keep it on a slightly (22:10):
undefined

Josh: lower setting for a lot of the work that you're doing. (22:13):
undefined

Josh: But outside of that, it's freaking awesome. I mean, this is a great upgrade. (22:15):
undefined

Josh: And now I feel good. Like when I opened up my Cloud app, I got Sonnet, (22:18):
undefined

Josh: which I'm not sure I really use Sonnet because I'm not burning through like (22:21):
undefined

Josh: a trillion tokens where I need it. (22:25):
undefined

Josh: But opus 5 and fable 5 are this unbelievable tag team that just work together (22:27):
undefined

Josh: so well there is also one one other nuance um fable speak which is like this (22:31):
undefined

Josh: kind of funny thing where (22:35):
undefined

Josh: it has a very unique way of talking it's very verbose that has been transferred (22:36):
undefined

Josh: to opus 5 as well i've noticed so opus 5 likes to talk a lot it likes to speak (22:40):
undefined

Josh: the way that fable does so that's an interesting little quirk um but outside (22:45):
undefined

Josh: of that i've been using the model i love the model opus 5 is great (22:48):
undefined

Josh: i think my ask to everyone who's listening is like hey are you using it what (22:51):
undefined

Josh: are you using it for best use cases, anything like that. Like this has been cool. (22:54):
undefined

Ejaaz: If you are on any kind of a membership on Claude or Anthropic specifically, this is the model to use. (22:58):
undefined

Ejaaz: Now I will say that although it is 50% cheaper than Fable, this thing thinks (23:04):
undefined

Ejaaz: quite a lot. It is a token guzzler. It uses a lot of tokens versus Fable 5. (23:09):
undefined

Ejaaz: But you have a higher allowance when you're using this particular model. (23:15):
undefined

Ejaaz: So if you're using Fable 5 and you don't want to pay access credits, (23:18):
undefined

Ejaaz: you should definitely be using this model. (23:22):
undefined

Ejaaz: The other thing I'll say is, I think this is very much Anthropik's response (23:24):
undefined

Ejaaz: to some of the Chinese open source model debate that's been happening over the last week or so. (23:28):
undefined

Ejaaz: Kimi K3 was launched by Moonshot Labs. It's a fantastic model, (23:34):
undefined

Ejaaz: almost frontier capability, but at a fraction of the cost. (23:37):
undefined

Ejaaz: And actually, as we're recording this episode, their model weight should become (23:40):
undefined

Ejaaz: open to day which means that you can kind of run it on hardware at home right (23:44):
undefined

Ejaaz: now they're good and bad things about this good is. (23:48):
undefined

Ejaaz: You know you can run it privately on your data it's arguably cheaper the bad (23:52):
undefined

Ejaaz: side of the thing is it has no safeguards around it which means that you could (23:55):
undefined

Ejaaz: potentially use it for cyber security threats or bio threats (23:59):
undefined

Ejaaz: moving forwards now the great thing about a model like opus 5 is it has those (24:02):
undefined

Ejaaz: safeguards in place so you know that anyone that's using it can't really maliciously (24:07):
undefined

Ejaaz: use it for any kind of mal intent and i think that there are pros and cons at both sides of things. (24:10):
undefined

Ejaaz: I know that a large number of companies, prominent companies like NVIDIA, (24:15):
undefined

Ejaaz: Microsoft signed an open source waiver this weekend. Anthropic was the one that (24:18):
undefined

Ejaaz: hadn't signed it, but they have their reasons for this. (24:23):
undefined

Ejaaz: And I'm excited for people to get their hands on Opus 5 and really tell us, (24:25):
undefined

Ejaaz: you know, what's your experience about this? Are you enjoying it? (24:28):
undefined

Ejaaz: Are you using it for any particular use cases that we haven't mentioned on this show? (24:31):
undefined

Ejaaz: It's a fantastic model. So get your hands on it and let us know in the comments (24:35):
undefined

Ejaaz: what your feedback is. But I think that is the end of the episode, (24:38):
undefined

Ejaaz: the recap of Opus 5 today. I encourage everyone to use it. If you're listening (24:41):
undefined

Ejaaz: to us or watching this on YouTube and you aren't subscribed to us, what are you doing? (24:45):
undefined

Ejaaz: Leave us a comment, give us a thumbs up. It helps us out massively. (24:48):
undefined

Ejaaz: If you're listening to this on Spotify or Apple Music, we are there. (24:51):
undefined

Ejaaz: Leave us a comment. We read everything, by the way, and your feedback is wonderful. (24:54):
undefined

Ejaaz: It influences what episodes we put out later on in the week and in the future. (24:57):
undefined

Ejaaz: We are also looking for sponsors. Josh and I have spun Limitless out on our (25:01):
undefined

Ejaaz: own and we are running this kind of like off our own budget. So if there's. (25:04):
undefined

Josh: Anyone out there- Thank you to Ledger for stepping up. (25:08):
undefined

Ejaaz: Yes, exactly. And thank you to Ledger for stepping up. and if there's anyone (25:10):
undefined

Ejaaz: else that would like to sponsor and advertise your product or service, (25:14):
undefined

Ejaaz: please let us know. We would love to hear from you. But I think aside from that, (25:17):
undefined

Ejaaz: That is it. (25:20):
undefined

Josh: That's everything. Thank you all so much for watching. We're coming at you live from... (25:21):
undefined

Josh: Ejaz and I are bouncing all over the place this summer. So we're just like kind (25:25):
undefined

Josh: of dropping in wherever we are in the world. (25:28):
undefined

Josh: Currently, I'm like up north of San Francisco. Ejaz is going to the West Coast. (25:29):
undefined

Josh: So we're doing this everywhere, but we're not missing the episode. (25:33):
undefined

Josh: So if anything does, you know, if the video goes in and out a little bit, (25:35):
undefined

Josh: we're doing this from remote, but we're getting the job done. (25:38):
undefined

Josh: And we appreciate all of you listening and being here with us for the entire (25:40):
undefined

Josh: journey. We will not let you down. And we appreciate all the support. (25:44):
undefined

Josh: So thank you for watching as always. We have another... (25:46):
undefined

Josh: We have a couple of really fun episodes coming up this week, (25:49):
undefined

Josh: so stay tuned for that. Let us know in the comments section all the things that (25:50):
undefined

Josh: we need to know in general, and we will see you guys in the next one. Thanks so much. (25:53):
undefined

Ejaaz: See you guys. (25:56):
