Fable 5.5 its over for video and image models 🤯 THIS IS PURE CODE one shotted this video holy shit , how this is more beautiful than ai video models Two ways to check this yourself: Ask: “Where did Andrej Karpathy go in 2026?” with web search and memory... turned off. Only the new Fable knows the answer. Then give it the prompt. Run the same prompt I used for the test (it’s in the screenshot) and see for yourself. Don’t rely on Grok for basic reasoning like this. Grok doesn’t have up-to-date knowledge of niche stuff. Either join the community or run the test yourself. Also, a knowledge cutoff doesn’t mean a model knows everything before that date. Sometimes a model doesn’t know about an event even if it happened before its cutoff. This test shows that too. Run the same prompt on regular Opus 5.5 and the quality drops. On Fable 5.1 it’s worse.show more

code for review : Prompt : Create a 2D anime scene for the web. It must look completely like real Japanese anime, as if it were taken directly from a finished theatrical anime film. This is traditional-looking, hand-drawn 2D anime, not a 3D animation, a moving illustration, or a stylized web graphic. Deliver the final result as a single, self-contained HTML file. Use any tools, libraries, references, guides, literally anything etc. Use Studio Ghibli films as the art style reference for the design, line work, painted backgrounds, color, and atmosphere. Create an original giant robot as the main character. No people appear in the scene. Use any tools or techniques you want, including 3D, as long as the final result looks 100% like hand-drawn 2D anime. SCENE At sunrise, mist hangs over an abandoned forest. A giant robot has knelt here for so long that moss, wildflowers, and old trees have grown over its body. A small bird lands on its shoulder as the first ray of sunlight reaches its weathered face. Deep inside its chest, a faint light flickers on. The ground trembles and birds burst from the treetops. With a deep, creaking groan, the robot slowly rises as soil, vines, and leaves pour from its armor. It lifts its head toward a gap in the canopy. The engines ignite, sending a great ring of wind across the forest. The robot tears into the golden sky, leaving a curving trail of light and mist as leaves spiral down through the sunbeams. ANIME QUALITY STANDARD Every frame must look as if it was drawn by professional anime animators and painted by master background artists for a finished theatrical film. Robot: A hand-drawn anime mecha that feels heavy, ancient, and full of personality, with cel-colored forms, chipped paint, rust, moss, and believable weathering. Keep it on-model from every angle, and let its posture and glowing eyes express emotion. Line art: Confident, delicate, hand-inked anime line work with subtle variation in thickness and pressure. Coloring: Traditional anime cel coloring with clean color areas, simple hard-edged shadows, and a soft, natural palette. Backgrounds: Richly detailed, hand-painted anime backgrounds in a gouache style, with visible brushwork, natural color variation, layered foliage, and real depth. Lighting: Golden sunrise light, colorful shadows, glowing mist, and soft atmosphere that unite the robot and background. Animation: Authentic hand-drawn anime timing with real weight, strong key poses, natural holds, and overlapping movement in vines, grass, leaves, birds, and falling debris. The robot should rise slowly and feel massive, then launch with explosive power. Direction: Cinematic anime shots, beautiful composition, thoughtful staging, and pacing that starts quietly, builds tension, and ends in a soaring climax. IT MUST NOT LOOK LIKE - 3D: No plastic materials, CGI shading, visible polygons, game-engine lighting, or computer-perfect perspective. - SVG or vector art: No simple geometric shapes, perfect curves, uniform outlines, flat corporate illustration, or basic gradients. - Web animation: No sliding layers, constant bobbing, floating parts, smooth software easing, or puppet-like joint rotation. You are free to change any part of the prompt, if it would result, in better results. - AI art: No warped shapes, melted details, flickering, or changing robot designs. - Non-anime art: No Western cartoon designs, realistic rendering, soft painterly shading on the robot, or generic digital illustration. - Amateur work: No stiff poses, empty backgrounds, repeated trees, muddy colors, clip art, placeholders, or unfinished details. The result should feel awe-inspiring, nostalgic, and full of wonder, like the moment an old forgotten dream comes back to life. Before finishing, inspect random frames as still images. If any frame does not look completely like real 2D anime, keep improving it. Do not stop until every frame could pass as a still from a theatrical anime film.

fully coded no external assets used and for all of you it made html code block as asked

thanks tuskedfriend for the work

@karpathy brooo wtfff. this is whole ass animation

@karpathy its over , 6 more months and nobody will care about new video or image model

@karpathy What is this!? That's crazy good! It's coming to destroy artists.

@karpathy OMG this looks so good

@karpathy we are so back

@karpathy is the new Fable public, or a test build somewhere?

@karpathy Great post, might be one of your best

@karpathy Holy sick 🤯

@karpathy Getting that level of volumetric clouds and pixel shading one-shot is unreal

@karpathy What the hell 😳

@karpathy Feels like a sensory lobotomy.

@karpathy 纯粹的代码一击必杀，这个形容很到位，比AI视频模型还美就说明代码本身的表达力被低估了，关键是这种美是能直接跑起来的，不是光好看。

@karpathy It's too exaggerated

@karpathy Golden age has arrived

@karpathy Fully coded??

@karpathy Wtf

@karpathy thats a 48mb mp4 in a trenchcoat bro, readme says the film is base64 and theres like 9kb of actual code

@karpathy opus 5.5 did this for me too, a 41 sec promo video for a product i built, all code. i ran it in the same claude code session where i built the product so it already knew every screen, i only asked for a few visual fixes

@karpathy This is really cool, but it's not as good as what video models can produce. To me it really undermines your credibility and comes across as a lack of taste on your part to state otherwise. Not trying to be mean, you seem like a cool dude, just a little too much hype for me.

@karpathy Video was so Amazing 😱

@karpathy I wish that you recreate all these prompts when the model is released to confirm if the expectations are correct

@karpathy for anyone opening the repo: index.html carries the film as a ~36 MB base64 MP4 (H.264, 1920x1040, 80 s) decoded into a Blob at load, and the only live canvas is the grain overlay. is the code that rendered the frames going up too?

@karpathy Totally agree, Grok can’t keep up on niche stuff. Fable’s code‑only approach is a game changer for this kind of reasoning

@karpathy video models have died more times than my tamagotchi

"Over for video models" is a stretch, honestly. Totally different tools. The cool part with code is every frame is computed: the robot never melts or morphs, and if you want a different shot you just tweak a number and re-run. Video models can't touch that. But you can see the limits too. The takeoff smoke is pretty obviously a few stacked sprites. Curious though: were those painterly assets drawn in code, or just loaded images? Kinda decides how "pure code" this really is.

@karpathy its not loaded images that for sure

@karpathy Video modelleriyle anime oluşturmaya ne zaman başlayacağız derken ne kadar vizyonsuzmuşum 🤦

@karpathy A clean one-shot is the easy number to show off. I'd care more about whether the tenth rerun looks like the first, since consistency across attempts is usually where video models fall apart.

@karpathy shot or the best of ten one shots?

@karpathy Giving studio Ghibli vibes

@karpathy damnn bruh ts looks so good!

@karpathy This is cleannn

@karpathy this looks incredible!

@karpathy one shot of pure code and it looks better than my video models tenth try

@karpathy Oh my. If this really turns out to be what they ship as Fable 5.5 then the leap in capabilities is insane. Not saying we should all use it as a video model, but the reasoning and detail behind creating this shows a badass capable model.

@karpathy İmpressive i like to see someone do animation with it to see its performance

@karpathy chetas please use it for motion design ull make millions of views

@karpathy like

@karpathy :)

@karpathy 1. recreating oai video launch 2. full motion like recreate a well known launch video
