Fable 5.1 is a beast at many things but one thing in particular I have been having a ton of fun with is generating videos through code. For this one I gave it a picture of a property lot. It designed a house for the lot, rendered it, and produced a cinematic walkthrough.

Using Fable 5.1, we’ve elicited a decoding of a cipher that has been unsolved for 373 year, and listed as #28 on Klaus Schmeh’s (the most-published cryptology author in the world) “The Top 50 unsolved encrypted messages.” The solution? Almost embarrassingly simple in hindsight.

Snake game build by Fable 5.1 this has to be the best frontend design build by an AI with excellent sound design for a snake and apple game

I was not familiar with your game Fable 5.1... Same prompt. Unbelievable.

Had early access to Claude Fable 5.1. Its a real advance in long-run work that requires judgement and taste, but less of an advance in the Claudish. Here is a game from Fable 5.1 with retro graphics where you run an accurate space ship inspired by FTL

Anthropic Claude Fable 5.1 just released and it's insane. I made this ARC Survival game with just 1 prompt and played it multiplayer with my 2 friends. Using Tesana I was able to make this game in just a few hours. This game has over 20h+ gameplay with cooking, crafting,

🔥Fable 5.1 deserves the insane title for sure! I just had it make a quick game in 10 minutes in @threejs and then also edit it. Editing took longer than making the game but just look at this!!

I WAS WRONG, FABLE-5.1 MIGHT ACTUALLY BE THE BEST MODEL TO EXIST ON THIS PLANET FOR FRONTEND TOO 😭 Tried recreating the exact same game with Fable-5.1 and Kimi K3. Fable-5.1 outclassed Kimi K3 on UI and gameplay. Smoother mechanics, better interactions, and noticeably more

Claude Fable 5.1 ONE SHOTTED this Mario Kart game. This is one of the best results I've had so far and I am SUPER impressed with the game development capabilities. Fable 5.1 is a huge step up from Fable 5.

HOLY SHIT FABLE 5.1 IS LITERALLY AGI. 😭 My friend @INONONO_66 fired it up on Claude Code the second it dropped, gave it a single shot, and in JUST ONE TURN it literally built full Super Mario: - Background BGM & sound effects - Fireballs & mushrooms - Spot-on Mario sprit

THIS IS INSANE! In just two prompts, Claude Fable 5.1 built this Titanic game. The goal: don't hit the iceberg. Try it: It includes: - Cinematic and gameplay views - Steering and speed controls - A reward system and missions - Built with threejs and

Fable 5.1 made this shooter with just this short prompt. Honestly, I'm completely fucking blown away. Prompt: "Make me the most insane and blast of a shooter you can possibly build on ThreeJS + Web shaders bro! The most important things are shooting, dynamics, recoil, graphics,

One of the wildest things buried in the Fable 5.1 release: Claude turned 30+ year old NASA radar data into a new high-resolution map covering a third of Venus. Resolution improved from 10–20 km to roughly 2–3 km. This is one of the small shield volcanoes from the map.

Fable 5.1 just dropped 5.1 on low beats Fable 5 max in the benchmarks. I had it create this subway surfers game, it looks great but some elements are surprisingly broken. Its very early, but my first feelings are this seens like a small bump, not a ground breaking update.

Fable 5.1 voxel pagoda test File: 617 lines, 31.9 KB. Rough estimate is ~10–11k tokens of output for the file itself, based on typical code tokenization (~3 chars/token). Scene build time: 658 ms in a Node test run before I shared it. In Chrome it should be similar, then the

Fable 5.1 is out! In this demo, Claude built an interactive model of the human brain from scratch. It sculpts every fold of the cortex in code, then follows one sentence, "Could you pass the salt?", as it moves through. Timings come from published EEG + MEG recordings.

Fable 5.1's cost gap is still huge. On AI/ML API's (@aimlapi) 1-shot Three.js test, Fable 5.1 cost $5.69 versus $0.88 for GPT-5.6 Sol. Fable spent that extra budget on scene density: waves, shoreline depth, thousands of chandelier crystals, a much larger water-park structure,

Fable 5.1 on the NYC prompt. Opus 5 underneath. It told me straight out this is not the best it can do, that going further would cost too many resources. First time a model has said that to me on this test. You can see it. 1,292 lines against Opus 5s 11,653. The camera never

Fable 5.1 same prompt for the ship in a bottle Ocean is 4,080 instanced voxel columns. Height = swell (4 travelling wave components) + a ripple field solved each frame with the 2D wave equation, damping, and reflection off the glass and the island. The ripple field is advected

Trying Fable 5.1 in unreal engine. I’ve got a pretty serious physics game demo prompt to toss at it with the MCP. 5.6 Sol did well on this, in an environment like Unreal Engine there is so much room for improvement! Claude typically is better in 3D so I’m super curious..

We made Fable 5.1 compete against Entelligence Router on the same coding task. Both had the same harness and infra, and had to build a GeoGuessr-style game from scratch, implement the interactions, and verify everything in the browser. Fable 5.1: 21 min, $22.16 Entelligence

I tested Fable 5.1 vs Kimi K3 I gave 3 same prompts to both, here are the results IMO, both created beautiful scenes, but the color picking problem is still there in Fable 5.1. Kimi K3 is better at this. Fable: ~$12/scene | Kimi: <$5/scene More tests coming up

@Bhavani_00007FROM X

Fable 5.1 made my benchmark saturated and I am happy about it. Most models struggle with the marble, Fable 5.1 fixed that. I will test this benchmark on Astra and sunset it.

@Conor_D_DartFROM X

Just ran Claude Fable 5.1 on my hardest benchmark suite, no collisions, lots of constraints. It completely destroyed every other model and made Chinese Frontier Models feel instantly outdated. The generational leap over Fable 5 is straight-up absurd.

@OmedVibeCodesFROM X

Fable 5.1 first impressions on 3d models. Not a huge change, but there is progress. I like that Fable 5.1 created the HTML file and then spent time testing it afterwards. More tests on the way
