145+ prompts. 145 things people made with Claude Fable 5.2 in its first week, from Blender films and Three.js scenes to games, fight animations, music and paintings, each credited to its creator and linked to the original post, with the prompt where the creator published one. Fable 5.2 does not draw pixels: every piece here was rendered from code it wrote.
Claude Fable 5.2 (model id claude-fable-5-2, released by Anthropic on 9 November 2026) is a language model: it takes text and images and returns text, with a 1M-token context window and up to 128K output tokens. It does not render pixels or synthesise sound by itself. Every film, game, song and painting on this page came from code it wrote, such as Blender Python, Three.js and raw WebGL, Canvas, Web Audio, numpy or LilyPond, which an agent like Claude Code ran, rendered and usually encoded with FFmpeg. Many of the best-known results started from one or two sentences, but the runs behind them were long: the pelican film wrote about 4,800 lines of Python in a session of about 1.1M output tokens, and the FPS level ran for 8 hours at about $550 by its author's account. The 145 cases were posted on X between 4 and 11 November 2026; the few posted before 9 November are pre-release tests their authors labelled "Fable 5.5". 38 cases have the prompt as the creator published it (9 long briefs are excerpted, with our outline), 20 have only the creator's one-line request, and 87 were never published. On apimodels.app, Fable 5.2 costs $4.80 per 1M input tokens and $24 per 1M output tokens, against Anthropic's $8 / $40 list.
Photoreal 3D pelican riding a bicycle, driven from Claude Code
Make a video of a 3D pelican riding a bicycle, as realistic as you can make it: believable anatomy and feathers, a real bicycle with working drivetrain motion, physically plausible riding animation, real-world lighting and camera. Take the time it needs. Deliver a finished video file.
What it is:
A photoreal short of a 3D pelican riding a bicycle. Fable 5.2 drove Blender 5.2.3 headlessly from Claude Code, writing about 4,800 lines of Python for a 21-bone rig, feathers and a drivetrain that actually turns, and Cycles OptiX rendered the 444 frames on an RTX 5080 in 56 minutes (technical details in the author's reply, x.com/techfren/status/2119926681716834440).

Steam locomotive transforms into a robot in a 2D anime short
Excerpt
Create a 2D anime short. 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. …
A 90-second short in the style of 2D Japanese anime, in which a steam locomotive transforms into a robot. Everything was built in Blender with Python and rendered in Eevee with line art, and even the score was written in code, synthesized with numpy oscillators (see x.com/0kncn/status/2120060332194287853).

How the brief is built (our outline):
Opens with the deliverable and the bar: one 90-second MP4 at 1920x1080 and 24 fps that must look like hand-drawn theatrical 2D anime, built in Blender from Python, rendered in Eevee, then inked and painted frame by frame in a second pass, with a synthesized soundtrack. HERO fixes the design with hard numbers: a 1940s 2-8-2 freight locomotive 23 m long that becomes a 21 m robot, down to the rust, the moss and a stork's nest on the cab roof, and requires an original design. TRANSFORM splits one 120-frame transformation into five 24-frame stages and rules out cheating: every part is rigid, nothing stretches, vanishes or appears, and each piece moves on a hinge or slide you can see. WORLD and STORY lay out a real-scale mountain railway (a 126 m viaduct of seven 18 m spans) and the plot beat by beat, from the rockfall to the robot staying behind as the new pier. LIGHT and SOUND set the look (high-key cel light, gouache backgrounds, effects drawn on twos, no particle mush) and a 144 bpm grid where every cut lands on a multiple of 5 frames and 16 music hits land on picture. FORMAT asks for a Python "story clock" with one state per frame; CHECKS has a script test every frame for parts passing through each other, wheel slip, sliding feet and the camera entering a mesh before the final render.

Game-ready 3D zombie war eagle built through Blender MCP
Excerpt
You are building a game-ready 3D creature in Blender through Blender MCP (execute_blender_code for actions, renders and viewport screenshots to check your work). The attached image is the reference. Goal: an outstanding, realistic, production-quality model that matches the reference as closely as possible. …

How the brief is built (our outline):
Sets up the agent before the art: which Blender MCP tools to use, a working folder, a saved .blend after every stage, and "never ask me questions": when unsure, pick whatever is closest to the reference and continue. WHAT IT IS gives size, units and orientation (about 1.6 m tall hunched, about 4.2 m wingspan, metres, facing -Y, feet at Z = 0) and asks for a static model in the reference pose, with no rig and no animation. THE REFERENCE, PART BY PART walks through the skull, beak, eyes (one blind, with a scar cut into the geometry), body, shoulder wound, wings and the natural and mechanical legs, naming sides as "its left (right side of the image)" so they cannot be confused. HOW TO BUILD IT orders the work: a blockout against an orthographic reference camera, a subdivision-ready body mesh, feathers from a 2048 px atlas of 10-16 feathers it draws itself in numpy (flagged as the step that decides the look), the wound, both legs, then PBR materials. CHECKS, GAME LIMITS and OUTPUT close it: at most 80,000 triangles and 4 texture sets of 2048 px, a GLB under 30 MB with named objects, six named renders including one beside the reference, and a short report.

Rigged cartoon zombie hand that crawls and does a backflip
Excerpt
Using Blender's Python API (bpy, bmesh, mathutils), build a complete animation pipeline from scratch and get it right on the first pass:
1. Model an original stylized cartoon zombie hand with stylized wounds, stitches and a severed stump at the wrist.
2. …

Note:
The prompt is transcribed from a third-party repository, github.com/yihui-dev/awesome-fable5-2-videos, which cites the Higgsfield blog as its source; this page shows only an excerpt.
How the brief is built (our outline):
Opens with a five-step pipeline in Blender's Python API, to be right on the first pass: model an original cartoon zombie hand, build a production-style rig with custom controllers (IK/FK, gizmo rings, curl sliders), animate it, shade and light it, and render on a cloud GPU. Modelling covers the silhouette, the zombie details on the back of the hand and the stump, and animation-ready topology. Animation runs in two passes: key-pose blocking first, then curve polish in the Graph Editor for overlap, weight and floor contact. The output is one 20-second, 1920×1080 video that shows both the rig and the render. Before the full render it must render six check frames locally (including the mid-air backflip and a pose with the controllers visible) and review each one for twisted fingers, torn mesh and loose wounds. The cloud render has a cost gate: list GPUs and prices, check nothing is already running, quote the job with expected and maximum credits, and start only after a yes; then follow the job until there is a finished video.

The first line is a build contract: one self-contained three.js page, a 14-second animation at 1280x720 and 30 fps, deterministic, exposing window.renderAt(t) so any frame can be captured. The scene is a floating voxel island: Paris in 1888 with the Eiffel Tower under construction, and everything already moving on frame 1. The tower gets the most detail: dark wrought-iron lattice made of thin voxel beams with real X-bracing, "not solid blocks", built level by level with scaffolding, cranes and rivet sparks. A "life" list fills the island: hundreds of people about 3 voxels tall, cranes, horse-drawn carts, a riverboat, carriages and pigeons. Camera and look close it: a slow orbit of about 25 degrees with a push-in, late-afternoon sun, ambient occlusion, haze, ACES tone mapping and bloom on the sparks.

How the brief is built (our outline):
Frames the piece as No. 063 in a series of "web material studies", built as one self-contained page with no libraries: raw WebGL2, Web Audio and a 2D pixel buffer. PAGE sets an editorial layout with three readouts, page colours that follow the depth, and support for phone widths. THE SWITCH specifies a 176×50 pixel-art cross-section redrawn on the CPU every frame and shown with nearest sampling, a glass "bathysphere" knob drawn in a fragment shader (about 1.28× magnification, RGB split at the rim, Fresnel tint, two highlights), spring motion with squash and stretch, and keyboard and ARIA slider controls. THE SEA lists every sprite zone by zone, from a beach with a sandcastle down to the abyss, with creatures that react as the knob comes near. LIGHT AND THE DIVE describes Bayer-dithered daylight that falls off with depth and a searchlight that comes on below the shallows. SOUND specifies an 84 BPM four-bar loop in D minor on one lookahead clock, five layers that fade in by depth and a list of interaction sounds; READOUTS map depth from 0 to 6,000 m onto zones and music.

How the brief is built (our outline):
Uses the same build template as Deep Dive Switch (this is No. 062 in the same series): one self-contained page with raw WebGL2, Web Audio and a 2D pixel buffer, in an editorial layout with readouts. THE SWITCH keeps the jelly-glass knob shader and the spring physics, and adds that the room seen through the knob is always fully lit. THE ROOM lists a cosy pixel-art room object by object; LIGHT AND THE MORNING has the knob drag dawn across it, day on one side and night on the other, with a 4×4 Bayer-dithered edge. THE STORY, BY POSITION ties events to the knob: a tabby cat goes from asleep to dancing in sunglasses, and from about 08:24 on the wall clock a puppy knocks at the door until it is let in. SOUND specifies a 100 BPM loop in F with five layers by position, and describes the door knock down to its frequencies (a thump sagging from about 98 to 60 Hz) and how far the music ducks under each hit.

Fable 5.2 writes a Python script against Blender's API, runs it headless with blender -b -P, renders a few preview frames, looks at them and fixes the script before the final render. Some creators drive Blender through an MCP server instead of a script file.
Strengths
Real lighting, materials and physics; Cycles or EEVEE output at any resolution; the scene stays editable as a .blend file.
Limits
The Python API changes between Blender versions, so scripts written from memory break; long renders need a GPU or rented machines; character assets still take many rounds.
Prompt template (our synthesis, not any creator’s original)
Make a [length]-second Blender shot at [1280x720, 24fps]: [subject], [camera move], [light and time of day], [mood]. Command line only, everything generated in code, deterministic keyframes. Show me the --preview frames and what you fixed before you run --final, and tell me the expected render time first.
Fable 5.2 writes a self-contained page in Three.js, raw WebGL or Canvas that exposes window.renderAt(t). Playwright captures every frame and FFmpeg encodes the MP4. Games and interactive pieces ship as the page itself.
Strengths
Nothing to install beyond a browser, Node.js and FFmpeg; any frame can be re-rendered on its own; the same page doubles as a live demo.
Limits
Photoreal people and natural motion are hard in code; physics that accumulates over time has to be stepped in order; long pages can run to thousands of lines.
Prompt template (our synthesis, not any creator’s original)
Make a three.js scene: [subject], [camera move], [light and time of day], [mood]. [length] seconds at [1280x720, 30fps]. One self-contained page, renderAt(t), everything generated in code. Capture key frames, look at them and fix what looks wrong before you tell me it is done. Then export scene.mp4.
Music and sound effects are synthesised in Web Audio, numpy or another language, or written as notation such as LilyPond, often on the same timeline as the picture so cuts and hits line up.
Strengths
No licensing questions for the soundtrack; every hit can be placed to the frame; the score can be regenerated with the video.
Limits
Synthesised instruments sound synthetic; vocals are the hardest part; judging the result still needs human ears.
Prompt template (our synthesis, not any creator’s original)
Write the soundtrack in [Web Audio / numpy] on the same clock as the animation: [tempo] BPM, [key], [instruments]. Place a hit on every cut and on [events]. Render a WAV, mix it under the video at [-14 LUFS] and tell me where each hit lands.
How to write great Claude Fable 5.2 prompts
1Say what done looks like, then let it take the time. The pelican prompt is three sentences, but it names the deliverable (a finished video file), the bar (believable anatomy, a drivetrain that works, real-world lighting) and gives explicit permission to work long: "Take the time it needs."
2Pin the design with numbers, not adjectives. The anime locomotive brief gives lengths in metres, a 120-frame transformation in five 24-frame stages and a 144 bpm music grid. The zombie eagle brief sets a triangle budget, texture sizes and a file-size limit. Numbers give the model something to check its own work against.
3Make every frame a function of time. For browser work, ask for one self-contained page that exposes window.renderAt(t), as the voxel Paris brief does, so a headless browser can capture any frame on demand at a steady frame rate. In Blender the equivalent is a script that sets every state per frame; the anime brief calls it a story clock.
4Make it check its own renders before the expensive one. The strongest briefs end with checks: render six key frames and review them (the zombie hand), test every frame for parts passing through each other or wheels slipping (the anime short), look at stills from both sides of every cut (the robot night market). Fable 5.2 reads images, so the review loop runs on stills.
5Put stops and a cost gate in front of anything paid. The robot night-market brief stops twice for approval; the zombie hand brief makes it quote the cloud GPU job, with expected and maximum credits, and wait for a yes. Reported spends on this page run from $5.75 of rented GPU time for a 4K Blender render to about $550 for an 8-hour game build.
6Give it a reason or a persona when the task is open. The most-liked painting post here had the model invent a painter persona before it painted, and another creator asked it to paint what it feels like to be the model. One-liners can travel too: "invent a new musical form" drew about 132K views.
7Choose the effort level on purpose. Creators here report medium (an open-source trailer), High (a lighthouse scene) and Extra High (a Bach chorale in LilyPond). On the API Fable 5.2 defaults to high effort; Claude Code and the Claude apps default to medium, per Anthropic's launch post. Raise it for long one-shot builds, keep medium for small fixes.
Prompt formula
Creative coding brief = the deliverable and its format (an MP4 at a set size and frame rate, or one self-contained page) + the design pinned in numbers (sizes, frame counts, tempo, budgets) + a build contract (renderAt(t) or a per-frame state, which renderer) + self-checks on stills before the final render + stops and a cost gate before anything paid + permission to take the time it needs
Example (our template, not a creator's prompt): Make a 20-second Blender shot at 1280x720 and 24 fps: a lighthouse on a rock at dusk, waves breaking, the beam sweeping through the spray, a slow push-in. Build everything in Python from an empty scene and compute every keyframe from the frame number. Render 4 preview frames at 25% size, look at them and list what is wrong before each change. Before the final render, tell me the seconds per frame and the total time, and wait for my OK. Deliver one H.264 MP4. Take the time it needs.
Frequently asked questions
Can Claude Fable 5.2 make a video, a song or a painting by itself?
Not directly. Fable 5.2 takes text and image input and returns text. Every piece on this page was rendered from code it wrote: Blender Python rendered by Blender, Three.js or WebGL pages captured by a headless browser, Web Audio or numpy for sound, canvas stroke engines for paintings, and FFmpeg to encode the result. In a chat window you get code or an HTML page you can open; to get an MP4 you need an agent that can run commands, such as Claude Code.
Did these really come from one prompt?
Some did. The FPS level, the pelican film and the browser Minecraft clone started from one or two sentences. But one prompt rarely means one quick reply: reported run times range from about 20 minutes to 8 hours, one open-world game was built over 7 days, and several creators added follow-up messages. Other cases ran on briefs of about 6,000 to 9,400 characters. Every card says whether the text is the creator's prompt, an excerpt of it, only their one-line request, or unpublished.
How much did these cost?
As the creators reported them: $7.48 and $8.43 for the two pixel-art switches, $21 for the Stonehenge scene, $22.62 for a Swiss lake painting, $34.96 for a 2,000-line Three.js short, and about $550 for the 8-hour FPS level. A 4K Blender render on 10 rented GPUs cost $5.75 in GPU time. This kind of work is output-heavy: the pelican run wrote about 1.1M output tokens, which is about $26 of output on apimodels.app at $24 per 1M, or about $44 at Anthropic's $40 list price.
What do I need installed to make one?
An agent that can run commands (Claude Code or similar) pointed at Fable 5.2; Node.js with Playwright and FFmpeg for anything rendered in a browser; Blender 5.x for the Blender cases, plus the Blender MCP add-on for the cases that used it. A GPU helps for Cycles, but EEVEE runs on a laptop: our own starter script renders 72 frames at 1280x720 in 77 seconds on an Apple M4. Music cases use Web Audio in the browser, numpy or LilyPond.
Which effort level should I use?
Fable 5.2 defaults to high effort on the API; Claude Code and the Claude apps default to medium. Raise it for long one-shot builds where a failed run costs more than the extra tokens, and keep medium for small fixes and iterations. Creators on this page used medium, High and Extra High.
How do I run Claude Fable 5.2 through apimodels.app?
Set ANTHROPIC_BASE_URL=https://api.apimodels.app, your apimodels.app key in ANTHROPIC_AUTH_TOKEN and ANTHROPIC_MODEL=claude-fable-5-2, and Claude Code runs on Fable 5.2; the same key works on /v1/messages and the OpenAI-compatible /v1/chat/completions. If the primary upstream errors, requests switch to a second channel automatically, and failed requests are not billed. It is billed per token: $4.80 per 1M input, $24 per 1M output and $0.12 per 1M cache reads, with no subscription.
Can I reuse these prompts and videos?
The works belong to their creators. Clips from X play straight from X's own servers, every card links to the original post, and we do not host or re-upload any of them. Published prompts are quoted with credit and a link: in full when short, excerpted when long, and never filled in when unpublished. Check the original post before using a prompt commercially. If you made one of these and want the card removed or the credit corrected, email us.
