Claude Fable 5.1 just dropped and I can't believe it...

0:00Claude Fable 5.1 just released and what it's capable of is mind-blowing. It is a clear step up in every single way from Fable 5. But here's the thing, if you don't use it the right way, you're going to waste tons of money. In this video, I'm going to cover all of the changes implemented in the Fable 5.1. I'm going to cover all of the ways it got better and most importantly, I'm going to be showing you how you should be using it today to get the absolute most this revolutionary model. Now, let's lock in and get into it. So, Claude Fable 5.1 just released. It's mind-blowing. Quick look at the

0:37benchmarks. We'll spend 3 seconds here. It's a step up in every single way, but what really blows me away here is if you look up at just how big of a step up this is. Right? I mean, it is doubling the percentages in some of these. It is blowing it out of the water. Typically, what you see with these small .1 step-up models are is you'll get 5, maybe 10% if you're lucky. What you can see here is research, literally double. Agentic coding significantly higher, blows out 5, 6 Soul. What I think is the most interesting part of this though, and I'm going to get into this a little bit

1:12later as well. I'm going to go super deep into why I think this is. It is clearly the biggest step up when it comes to scientific research. It's clear that scientific research was the big focus with this model. I think there's a big reason why. I think that changes kind of the entire industry. We'll get into that a little bit later, but as you can see here, the step-ups are absolutely massive in basically every single way. Other than the scientific research, this is the other way I'm

1:44really excited about Claude Fable 5.1. It is significantly more efficient than Claude Fable 5. You're going to get anywhere between 25 and 40% savings on whatever task you do That's why task you do with Claude Fable 5.1, the cost to do that task is going to be roughly 25% lower than Claude Fable 5, which as you can see here was just absurdly expensive. So, you're going to get a lot of savings. You're going to get a lot more usage out of a much better model, which is amazing. But, here are the big improvements. Here's how I'd personally categorize the big improvements. One as I said, substantially cheaper, same

2:23price, right? The cost of this model and Fable 5 are the same price per token. You're just going to get things done in less tokens. So, you're going to be saving lots of money. It's substantially smarter in every single way. I showed you that in the benchmarks. I'm going to show you that with the world-famous Alex Finn benchmarks in just a second. The benchmarks the entire world has been waiting for. Dario actually texted me this morning. He was like, "Man, you got to let me know how it goes with the Alex Finn world-famous benchmarks." I said, "You got to wait. You got to wait till

2:53the Finn fam sees the benchmarks first." So, I'll be showing you that in a second. Way better filtering. What do I mean by that? With Claude Fable 5, it was triggering like content filters left and right. You'd ask, "Hey, what's 2 + 2?" It'd be saying, "Wait, that's too dangerous. You might blow up the world with that question. I'm going to give this to Opus 5." No longer with Claude Fable 5.1. My tests have shown that it actually is willing to answer way more questions. I'll show you that in a second as well in the benchmarks. Way better filtering. Thank the Lord. And then built for research, aka novel

3:26ideas. As you saw with the benchmarking, it is clearly built for research, and I have an idea why. I'm going to go through that during the use case section of that. So, stick around for that. You're going to love the use case section. I'm going to give you a bunch of use cases. They're going to be amazing. Stick around for that. Let's get into my own personal benchmarks to prove that Claude Fable 5.1 is so much better. It blew out GPT 5/6 sole in my benchmark. Starting with the roller coaster test. Here it is. Let's check

3:56out GPT's roller coaster test first. Task was to build a 3D roller coaster simulator as you can see here. It looks pretty nice. Let's click the ride button and see what this looks like. Looks pretty good. I'll end the ride and you can see it going along. You actually can't see too much of the cars going along there. So, it's decent. But, let's

4:16check out Fable 5.1. As you can see, so much nicer. So much more detail, way more buildings, way more details in the buildings. The trees are more detailed. The grass has way much more texture to it. It looks amazing. Let's go on the ride here. As you can see, look at the track. Look at the colors and track. Look at the individual tracks made there. Looks so much nicer. The clouds, the sky,

4:40everything has very nice detail in it. We have the debug duel where it actually pulled down a random GitHub repo and tried to find all the bugs in it. Fable 5.1 actually found all of the bugs in significantly less tool calls than GPT56. So, it's much more efficient and uses much less tool calls to get better if not the same results. Also gave it the gauntlet, which is an agentic task where we give it a bunch of different files and we have it find little Easter eggs in all the files. They both completed it really well. Fable 1 was just be able to do it a little bit

5:14better, so it got a higher score. Overall, Fable 1 beat 5.6 Soul pretty easily. Let's look at Fable 1 versus Fable 0. And as you can see, Fable 1 absolutely destroyed Fable 5 really, really easily here as well. Here's the big one. Look at this. Fable 5 absolutely refused to do the relic hunt. In all my tests I've done with Fable 5, it has never, ever, ever done the relic hunt. The one where we give it a bunch of files and tell it to find Easter eggs

5:41because it triggers the content filters. That's not the case with Fable 5.1. Fable 5.1's willing to do it. The filtering is so much better with this. Things Fable 5 refused to do, Fable 5.1 does it better and it does it smarter. If we look at the pixel-perfect test, which is its ability to clone apple.com, let's take a look here. So, this is Apple's real site. This is what you see when you go to apple.com. You can see it has the devices, Ted Lasso, a bunch of other things here. Let's show the recreation of Fable 5.1. Looks pretty good. Does it look perfect? No. But, you can kind of tell these are iPhones,

6:16MacBook Air, Mac Mini, iPad Pro. They all have the general shapes of it. Let's take a look at Fable 5 to see what that did. As you can see, the Apple logo doesn't really look like the Apple logo. The people are just a bunch of squares. iPhone looks pretty good, but the devices you can't even really tell they're devices at all. Ted Lasso, you can't tell it's a human being. Sabrina Carpenter is just two circles. So, Fable 5.1 blew out the recreation test as well. Now, let's talk about the first thing you should be doing Claude Fable 5.1. Here's one of my favorite things to

6:46do, an audit of your AI agent setup. What I did was I went into my Grok bot, which is my main AI agent right now. You can do is use Hermes, you use Open Claude, whatever you use, you can do this. Go to your main orchestrator agent in that setup and say, "Hey, I want to run an audit of my setup with Claude Fable. Can you do me a favor, create a markdown file that describes our entire AI agent setup, skills, sub-agents, all that, put it into a markdown file." You download the markdown file. You go into Claude Fable 5.1, you drop it in, and you say, "Hey, can you look at my agent

7:22setup and let me know ways we can improve this agent setup." Claude Fable 5.1 is great for this use case because it is incredible at coming up with novel ideas. It is probably the best model ever when it comes up with novel ideas. And we talked about this a little bit earlier, right? If we take a look at the benchmarks again, It is built for scientific research. Scientific research is all about breaking subjects down to first principles and then coming up with novel concepts based on those first principles. Right? So, this is perfect for taking look at things you're already doing, setups you already have, feeding

8:00that into Claude Fable 5.1, and then having it audit your setups and come up with new and fresh ways to do the things you're currently doing. So, whatever your current agent setup is, go to it, say, "Hey, make me a markdown file describing everything in detail." Drop it into Claude Fable 5.1, have it audit it, and then take those new ideas and implement them. Here's the second thing I'd be doing with Claude Fable 5.1. I'd take your last few brainstorming sessions you did with Claude Fable 5,

8:30and I'd rerun them in Claude Fable 5.1. I've been taking all my ideas I was brainstorming with Claude Fable and just running them through Fable 5.1 to see if they can come up with new angles, new concepts, new ways to approach things. And surprisingly, they were able to. I've basically come up with whole new ideas by running the same prompts through 5.1 that I did with 5. Again, it's this research part. I was talking about this earlier. I think this is the

8:56biggest part about Claude Fable 5.1. They turned it into a true researcher. ChatGPT and OpenAI were talking about this a few weeks ago with Astra. They talked about how Astra is like their new research intern. I think what these AI companies are going for is coming up and building their own research interns. So, they can start the recursive self-improvement loop. If you can come up with a model that comes up with novel ideas, that can do research and come up with novel ideas based on first principles, you can have it improve itself, and that's why I think the focus for both Astra and now Fable 5.1 is that

9:37research intern, that research ability. Why it's at the top of all the benchmarks now is they're going for recursive self-improvement. So, the way you take advantage of this is turning Claude Fable 5.1 into your personal research intern. And the way you do that is by giving it challenges that need novel ideas. So, I'm building my own video game development studio. I'm using Fable 5.1 to build its own engine. When it comes to Henry Intelligent Machines, my new startup, I'm having it build the engine that powers it from the ground up from a first principles perspective. So, again, go back to Fable 5, find the ideas you were kind of bouncing off of

10:18that need novel insights, feed that into Fable 5.1 instead. You'll get much better insights because it's focused on that research aspect of the model. And then the third thing I'd have you do with Fable 5.1 right off the rip is do what I'm showing you right here. Build your own benchmark test harness. I built this Alex Finn world-famous benchmark, completely custom based on my use cases, completely custom based on things I do on a daily basis. So, my recommendation to you is this, you should do the same thing. You shouldn't trust other

10:48people's benchmarks, other than my own. You can trust the Finn world-famous benchmarks, but other people's benchmarks, don't trust them. What you should do, go into Fable 5.1, say, "Hey, what are the top five categories of tasks we do on a regular basis?" Then based on those five categories, come up with a complex multi-step test we can do for each to test AI models, then build a website around it like you see here. If you do that, Claude Fable 5.1 will come up with an amazing test harness that will allow you moving forward to test all the new model releases based on how

11:25you use them and your own use cases. This will make it so you'll know which models to use for which use cases, how to use them, which ones you should be going with so you can make your own judgments. Those are the three ways I'd be using Fable 5.1 off the rip that will, A, help you get the most value and, B, take advantage of what I believe

11:44are the biggest strengths of Fable 5.1. Lots more content on Fable coming soon. I think this is a game changer. I think we're about to see a long string of new Anthropic releases now over the next few weeks. We haven't got like a new Anthropic release in months now, which is staggering. This is the first one in a while. So, make sure to subscribe and turn notifications cuz the moment these new tools come out, I'll cover them and teach you how to use them.
