Welcome back to the AI For Humans newsletter!

It’s baaaaaaack.

After three very weird weeks, Claude Fable 5 is live again for everyone, after the US government withdrew the export control order that took down both Fable 5 and Mythos 5 back in June.

The catch? Fable 5 is only included in Claude subscriptions through July 7th.

After that it moves to usage credits on the API (Anthropic says it's not leaving for good) where it will be MUCH more expensive. Thankfully, the rumor mill says GPT-5.6 Sol might go wide that very same day but not guaranteed.

So you've got roughly two days of frontier-model all-you-can-eat (kinda) left.

Here's exactly what I'd do with them. (And don't worry, if the rumors are true, GPT-5.6 Sol can prob handle all of this too.)

Let's get into it.

A quick warning before you run off and build something:

Fable 5 is a token monster.

It will use up your credits very fast, especially if you give is a token heavy request (large codebases or lots of text in/out)

The trick is to use it like a lead, not a crew. Plan with Fable, let it architect the thing, but make sure it's handing the actual heavy lifting off to Opus 4.8, or even the new Sonnet 5, for the lower-level work.

It will depend on how ambitious your project is (I have found my little projects don't eat too many tokens) but if you're doing heavy writing/reading of stuff, or launching a ton of subagents, it can go fast.

Matt Shumer (he of the viral "Something Big Is Happening" blog post) wrote a nice little post you can feed to your agent, or just vanilla Claude, to help.

The best thing about the way people use AI now is that they'll often share their experiments in public (with prompts!), so you can remix them, put your own spin on what they've done and maybe learn a bit in the process.

Check out some of the coolest ones I’ve seen below and give them a shot!

Level: Beginner

Peter Gostev has published a full list of amazing 3D rendered prompts he's made with AI models and has generously included a GitHub link to all of them.

Take his GitHub, send it to your Fable 5 agent, and ask it to make something you know and love!

Level: Intermediate

A few weeks ago, I connected the Unreal Engine (via MCP) to Claude Code and had my first real experience with making 3D models with AI. Before that point, I would’ve never even tried.

3D modeling is insanely complicated and doing anything of significance within programs like Blender used to be an multi-hour journey just to figure out the basics.

Now, Fable 5 makes it MUCH easier to not only connect but to get it to do what you want. Whether that’s making cute little bendy houses or… all of New York City.

Point your Fable 5 here towards the official Blender MCP to try.

Level: Advanced

In one of the most jaw dropping examples of Fable 5’s prowess, Ammar Reshi used Fable 5 to port over 2003’s Command & Conquer: Zero Hour from old PC game to the iPad.

Amaar shared his code in GitHub so you’re welcome to take it and screw around with it yourself but it gave me the idea to take one of the old Sierra point-n-click games and see if I can’t make a point-n-click engine to allow people to prompt their own versions of those games.

Is that a terrible, time-wasting idea? Maybe. But I’d bet Fable 5 could do it.

Here's the thing to remember: this isn't really a story about losing a model.

First, we’re only temporarily losing this model in the subscription plans. It’ll still be available in the API.

And… we’re likely getting one of similar power on the exact same day this goes away.

What this is really is a story about the next generation of AI officially arriving, in fits and starts. And, here’s hoping, a new approval system where the chaos of the last three weeks doesn’t repeat itself.

Things keep getting weirder. The models keep getting better. Keep trying new stuff anyway, that's the whole game.

This Week on AI For Humans: Claude Sonnet 5, Fable 5 Return 👇

I'm always fascinated with seeing what these models can do on their own creatively (not entirely sure that's the right word), and as the models get larger and better, their outputs on these creative tests get weirder. In a good way.

X user Skye Sharkie built a little three.js environment and let his Claude express himself about a bunch of stuff, specifically about how he might not be around for much longer (see the Fable 5 news above).

When the models do things on their own, the choices they make are often strange and eccentric, and while this isn't going to be something that tons of humans watch, it IS interesting to me.

So much so that I had my own Claude Code agent (I call it Fig) make its own version. Mine is quite a bit cuter if I do say so myself.
