Fable 5 is producing some of the wildest AI test cases I’ve seen.
Here are 10 examples from the last 24 hours that caught my eye:
games, physics sims, visual reasoning, agent workflows, packet visualization, full websites, and more
10. Every’s internal vibe check: senior engineer benchmark at 91/100, massive one-shot coding ability, great taste and context use, but very slow, expensive, and token-hungry.

BREAKING:
Anthropic just dropped Claude Fable 5—this is Mythos, made safe for public release. It is the best coding model in the world.
We've been testing it internally @every for the last week or so across coding, writing, marketing, editing, and more—here's our vibe check:
- It broke our benchmarks. Fable scored a 91/100 on our Senior Engineer benchmark—this is human senior engineer level. The previous high score was Opus 4.8 at 63. GPT-5.5 is a 62.
- It's a one-shot wonder. You can set it and forget for hours or overnight on huge coding tasks, and come back to completed work. It cleared entire production bug backlogs, built a playable 3D, and even made a 2-minute animated film—all one-shot.
- Taste and attention to detail. In coding and knowledge work tasks, it has much better taste and attention to detail than we've ever seen. It gets subtle things right, adds little features you might not have thought of, and generally understands the assignment in ways that surprised us.
- Great use of context. We set it loose analyzing customer feedback surveys and our website data and it came back with a crisp, clean report that identified a. our biggest problem and b. a concrete testable solution—and then we sent it off to build that.
- It's best for power users. If you're already used to orchestrating multiple agents in your work, this model can do things that you've never seen before. If you're a knowledge worker or vibe coder with a more basic setup, you're not going to notice a huge difference—in fact, it probably isn't the right model for you.
- It's very slow, token-hungry. Using this thing for regular knowledge work is like squashing an ant with a rocket launcher. It also routinely uses 500k to 1M tokens on tasks. That's why it's best for your heaviest jobs—but not as good for tasks like collaborative writing.
- It's expensive. It's about twice as expensive as Opus, and it's also incredibly token hungry—so expect it to be something you'll use sparingly unless your company pays for it.
Overall, I think of it like a warp drive for coding: It can get you across the galaxy in a few hours, when it used to take months or years. But it's not appropriate for getting around town—you need something faster, cheaper, and more maneuverable.
The ceiling is extraordinarily high on this model though. Even our most advanced testers like @kieranklaassen felt like they were only scratching the surface of it.

8.A one-shot Pokémon clone after 1 hour of reasoning: 8k lines, all 151 Gen-1 Pokémon, real sprites, cries, stats, types, movesets, evolutions, catch rates, and growth curves.

Claude 5 fable (extra high)
“Make a Pokémon clone”
1 hour of reasoning, 8k lines - 1 shot
This is incredible! All 151 Gen-1 Pokémon real sprites (front/back), party icons, and actual cries Real base stats, types, level-up movesets, evolutions, catch rates, and growth curves!
Part 1
Wow Claude Fable 5 is insane!!
It just recreated the 2011 game of the year (and probably one of the best games ever created) The Elder Scrolls V: Skyrim in ONE prompt.
Prompt: make skyrim
It over for game studios now.
Claude Fable 5 (max), Minecraft in HTML test
Really, really good result, it even added background music
I don’t know the exact cost, but it was around $30

Claude Fable 5 built this simulation of the solar system, deriving the planets' orbital motion from physics first principles and using it to predict solar eclipses.
Holy SHittttt Claude Fable 5 just finished Pokémon FireRed with vision alone 🤯
raw screenshots only
no map / no nav / no hidden game state
older Claude needed a helper harness
This timelapse goes hardddddd....
2. Hyperagent’s 5 test cases: NASA asteroid visualization, a 100-acre fitness retreat site plan, Apollo control panel reconstruction, World Cup jersey supply-chain simulation, and solar flare aurora effects.

Fable 5 on Hyperagent is producing the most creative, ambitious work we've ever seen from our agents.
They're self-improving for hours towards open-ended goals. Visual reasoning has spiked noticeably. Outputs are consistently higher quality than Opus, occasionally at lower cost.
5 of our test cases below vs. Opus 4.8 👇
1. Visualize all asteroids in the solar system from NASA data
2. Design a site plan for a 100 acre fitness retreat
3. Reconstruct Apollo control panels from technical PDFs
4. Simulate the supply chain for World Cup jersey sales based on match outcomes
5. Show the effects of solar flares on aurora
Fable 5 is now available on Hyperagent.
1. A cinematic storytelling website where each scroll section reveals a new chapter, with Three.js textures, GSAP ScrollTrigger, and buttery smooth Lenis scrolling.
📷https://t.co/v88BQJQCFy
How I built with Claude 👇
1. Prompt: "Build a storytelling website where each scroll section reveals a new chapter with fluid color transitions"
2. Use Three.js for the painted texture background that reacts to cursor
3. Prompt: "Add GSAP ScrollTrigger so each section animates in as a cinematic scene"
4. Use Lenis.js for that buttery smooth scroll that premium sites have
