Claude Opus 5 DESTROYS Fable 5?

**Julian Goldie** (0:00)
Claude Opus 5 just dropped, and I can tell you right now, we've tested it across many different builds already. Only just dropped about an hour and a half ago, and it is an absolute banger. So I'm going to show you exactly how it works, how it performs, what the benchmarks are like, and what we've built with it so far. So just to recap, this is the announcement of Claude Opus 5, designed to be basically like the same level as Fable 5, but it costs half as much.
And you can see the full details here in terms of how it performs on the benchmarks. The reason I wouldn't pay too much attention to this is just test out yourself, because it's always different when you actually test these things, especially when the model first drops. So that's why we've built so many stuff. As you can see right here, we built all this stuff. I'll show you how it performs in a second. But yeah, it's pretty good for agentic terminal coding, knowledge work. It's also pretty good for computer use. But the main point here is like it costs a lot less. So for example, you can see Opus 5 versus Opus 4.8 versus Fable 5
And it basically achieves like similar levels of performance and even higher levels of effort than any other model. It's cheaper if that makes sense.
So that's one of the highlights and also very good at computer use. So you can see the announcement right here.
You can check out all the benchmarks. I'm not going to bore you with them because I think the most people are kind of over just generic theoretical benchmarks. You're probably just wondering, OK, is it good or is it not good, so let's get straight into this and let's have a look. So these are the builds you can see here, for example, this driving game, and we've compared it versus GPT 5.6 Soul over here, then we have Kimi K3 over here, and we have Fable 5 over here. And actually, even if you compare it side by side versus Fable 5, on this particular build, I'm not saying it's better than Fable 5, but I am saying like it's right up there. And it's super nice in terms of the detail, what it can create and that sort of thing. Some people as well watch this and be like, well, you know, why are you just using it to build games? Games just give you a good feel for like the look, the feel, how well it can predict physics, how well it can plan properly, and also the level of detail and the vibe of stuff you'll get when you build them with this. But so far pretty cool. Let's have a look at the next one. So this is Dragon Flight, as you can see right here. And again, like the graphics, the vibe, the details, the physics, everything is pretty much on point when it comes to this. It's holding its own, if not absolutely destroying some of the other options. So you can see how it performs and compares versus these other models. I would say it's right up there. Let's have a look at the arcade one here. So it's kind of like a 3D snake game that's created.
As you can see, honestly, this one is not like that interesting, not that fun to play. Basically, it's like a first person neon snake game. That's kind of what it looks like. Not quite as good as the rest, to be honest. It's not as fun to play. Let's have a look at the next one. So this one is cool. If we have a look here, this is pretty cool. Kind of like just a fun game to play. 3D controls are nice, easier to use and more fun than the other stuff that we created here. So if you look, for example, at GPT 5.6, it's good, but it just feels like a little bit weird when you're playing the colors and everything. And the same, for example, if you have a look at the Fable 5 comparison here, the controls are just a little bit less nice. And also when you're looking at this, the detail on the actual setup here from Claude Opus 5 is much nicer. And then if you have a look, for example, at Kimi K3, Kimi K3's version is not bad, but it's just a little bit boring. So look at the next one. So this is like a flying simulator game. Again, holds its own, if not better than all the other models, which is unbelievable when you think about it. We'll be running like 50 different builds and giving it a full score later on Goldie Bench, seeing how it performs on the leaderboards. But I would honestly say like you might be looking at one of our newest, most favorite models. I think the only things that are actually outperforming here are like when you've got fusion panels. So for example, if you have, for example, Fable 5 and Opus 5 working together, like that would be a nice fusion to see how they perform and how you can get better outputs. The other thing I will say on this particular example is like the controls are kind of weird, right? It just, it feels a little bit weird when you're flying around there.
