0:00All right, so I want to make one thing clear here. Claude Opopus 55 is the best AI model ever released and is the one you should be using for pretty much everything right now. So I was very lucky. Enthropic gave me early access to this model. I have been using it non-stop and when they took it away a couple days ago, I legitimately felt sadness. Just to start off with here, and I'll go through demos, take you through it, all that, show you what it's built, it is smarter than Fable, and it's not even really close. And it is smarter than Chad GBT6 Astra. That's right. It is the smartest AI model out

0:31there and yet at the same time it is significantly faster and it is significantly cheaper. So when Anthropic gave me early access to this model, they didn't tell me what the name was. They said, "Hey, here's a model. Test it out. Let us know what you think." And I could have sworn on everything this was going to be like Fable 5.5 or Fable 6 or whatever. Like it was just such a massive leap over the results I was getting from Fable. Then this morning they messaged me and they go, "By the way, that was Opus 55." I could not

1:00believe it. It's the first thing I said. I'm like, "No, there's no way. This is Opus." I mean, it was smarter than Fable. I was taking code that Astra wrote. I was giving it to Opus and it was going, "Oh, this code's disgusting. Let me clean this up for you." Like, it was just finding issues left and right with basically all the code any other model has written for me. The speed is unbelievable. I mean, I can't remember Opus ever being this fast. I mean, let's not even compare it to Fable or Astra because it is just light years faster than both of those, but even comparing

1:30it to previous Opus models, it just feels zippier. Like, I was testing it early and I thought, "Oh, they must have had some sort of breakthrough here cuz the speed is incredible." And so, they release it today. I finally get my hands on the benchmarks when they release it and I'm just like, I just can't believe it. They actually reduced the price. So, not only is it cheaper per task than any other model out there, they also just reduced the straight up price. You literally never see this. They decided, hey, we're just going to make less money on this model. I guess the idea is, and

2:01this is a great idea, if this model is so good, people are just going to use it more and we'll get more usage out of it and make more money off it. And it makes sense. It's both consumer friendly and friendly for the company. The price goes down, the cost per task goes down, and the intelligence goes way up. As you can

2:20see here, there's nothing even close. You can see Astra, it's smarter than Astra. The high setting on Opus 55 is better than the max setting on Astra 6. All while being like a fraction of the cost. I mean, you very rarely see this. This is like the trifecta of great speed, intelligence, and cost. all better, all improved, all like best-in-class. That is unbelievable. And if you're going to be using Claude Opus 55, you want to make sure you get the absolute best out of it. And the way you get the best out of it is with Claude Skills. Many people don't know how to set up Claude Skills, that's where my

2:56friends at HubSpot for Startups come in. They just put out this free resource that gives you five Claude skills that help you crush founder content. And once you have these five skills installed, you stop prompting Claude from scratch every time and start working with a system that already knows your workflows. Inside, you're going to get five installable skills that turn your raw work into voice matched channel ready content in under two hours. You got a voice builder that actually sounds like you. Look at this output. A weekly capture skill that takes your notes, Slack messages, whatever, and turns into actual real content. My favorite is the

3:34hook and angle generator. This has made creating content so easy for me. I just give it kind of rough ideas and it gives me hooks I can use, angles, drafts. It just makes creating content so nice. Grab all five skills from the link down below. And thanks to HubSpot for sponsoring the video. And now, despite all of that, that's not even the best part of this model. I've been talking to it non-stop for the last week and let me tell you this, it is the best model to talk to ever. There's been like this crazy issue going on with AI the last few months and it's been pissing me off

4:09so much. Basically, every model to come out since like Opus 48 has been unbearable to talk to. And this is across all of the different companies. This is Chad GBT, this is Grock, this is all of them. Basically, every model to come out from any company since Opus 48, which if my memory serves me correct was like May, has been unbearable to talk to. They've all developed like this weird language that they talk in that's like not even human. They use all these strange terms. They use smoke test a thousand times. They just like use this weird jargon that doesn't really make sense. And you read like paragraphs of

4:48text from all these models and you read it to the end, you go, "What did I just read? That is dead. That is over. They fixed it with Opus 55." What was amazing about anthropic models and why I like ride or died with Anthropic like a year ago was it was just straight up the best models to talk to. They felt warm. They felt human. They talked concisely. You It was just like pleasant to talk to the models more on a level than any other company out there. They lost it. It pissed me off so much. And now it is finally back. Opus 55 is just as good,

5:23if not better to talk to than Opus 45, than Sonnet 35, the OG model I love talking to. It's better that it talks human again. So, I'm going to go through so many of the things it does better right now with this live demo I've been doing. So, I've been basically been building uh this really complex game for the last week with it as as well as many other things, too. But I think this makes for the best demo. But the way it talks is so easy to read. So nice. The full build and four tests are running in the background. About 30 minutes. I'll be notified when they finish. And there

5:56are no test results yet. The build replaces the running binary. So I had to close your game. Like it just talks like a human being. If this was Opus 5 or Astra 6 or Gro 46 or whatever, while those are great, great great models, like the way they talk is like the full smoke test has passed. The smoke test has passed. the functionality and the binary has reset the buying boundaries and it is now up to you to be smoke test to make sure it is available and like it's just like all these extra words and jargon and this is just straight up hey we built it looks good here's everything

6:28we improved I'll look at the screenshots check the numbers and relaunch the game when it finishes every test passed here's the things we did it has like nice charts and tables very easy to read it's like they trained this just to be the easiest to read model ever bullet points make it super easy to read as well. I say, "Hey, there's a lot of issues with the game. What can we prove?" "Hey, I tested the game. Here's all the issues I'm seeing. You took 601 damage." Like, it just talks like a human being. It's also spectacular at debugging. I handed, as I said earlier, a bunch of code that I wrote with Astra

6:596, which again, Astra 6 incredible. It was my go-to model up until this point, but it took all the code. It just found so many issues. Like, I I I'm really really imp. And I didn't even ask it to debug. I just had said, "Hey, can you improve these things?" is like, "Oh, by the way, I found all these things. Do you want me to fix it?" It's just so good. It's so smart. It's so intelligent and feels human. So, I want to show you an example of like the depth and thinking it gives you in just a couple prompts. This is a full top-down 3D

7:26extraction shooter. It built in a few prompts. There's so much depth to this game, even more depth than I was getting out of Astra. And it does it so nicely with so few bugs. I think that's like kind of the underrated part here is like it writes bug-free code. I don't know how they train this model, but it's like shipping me the most code that's bug free that I've ever done before. So, let's just go and just look at this. So, you go in, it has this like entire weapon inventory system. You can go right in here and there so much depth to this game. It might not like look at it

7:58at first, but you go just first of all look at all the items in the game. Look at the map and everything in it. It has different locations. Now, we got enemies. I can kill the enemy. There's like a full like loot system. the loot reveals. You can put it in your, as you can see, there's like full equipment and all that. It's really amazing what it was able to build for me. The 3D modeling also basically just as good as Astro 6 has a full extraction system. I can hold E to extract. I get out with all the loot I came in with. By the way,

8:25would you play this game? Let me know down below. One other thing is its ability to come up with novel ideas. If you're anything like me, you do tons of brainstorming with your models. Opus 55 has been unbelievable at coming up with novel ideas. So, I just bought the new Apple Watch Ultra 4. I go to Opus 55. I say, "Hey, can you help me come up with ideas for how we can hack this, apps we can put on it, different AI things we can do?" He comes up with all these ideas, builds it out for me, and what we end up doing is I can now talk to my

8:57agents on my wrist. So, all my agents, I built this custom app for the Apple Watch where I can see all my agents working as they're building code or whatever, and I can hit a button and talk to them and text them while I'm on the go. No phone required. It just like came up with all these really interesting ideas. I said, "Yeah, that sounds good." And it went ahead, built it, figured out a way to like put developer apps on my phone and on my watch. I have no idea how to put apps like on my watch. I don't know how Apple iOS watches work. It just is like, "Hey,

9:26by the way, I put the app on your watch." I'm like, "No, you didn't." And I look down and there's just the app on my watch. I have no idea. I didn't plug my watch in anything. It just figured it out. So, it's super intelligent, super fast, super cheap. Comes up with these novel ideas. I said, "Hey, I have like 17 computers here. What are some cool things we can do with local models?" It set up this entire local model system for me. If you use AI to bounce ideas, which you definitely should be doing, just coming up, hey, how would you use this? What would you create here? What

9:54would you build here? This is like the best model for that ever. Now, the one downside is is like, do I believe the Clawude Code harness is as good as the Chad GPT harness, for instance? No. The Chad GPT harness has like voice mode, which is just like mindblowingly good. Claude does have a voice mode, but it is not quite as good as Chad GPT's voice mode, although I'd expect Anthropic to come out with improvements for that soon. So, the harness isn't quite there yet, but this model is so good that I do believe you need to be using it. It solves basically every problem and

10:31challenge Anthropic has had for a while now. From usage, it's way more efficient to the way it talks, it's way easier to talk to to just being able to get things done. They finally are back. Anthropic is back. They've been out of the game for like five months now, which has been really unfortunate, but they are back. And when companies come back and they compete, us the consumer always ends up winning. We are again in the two most exciting weeks in AI history this week and next.
