Anthropic released Claude Fable 5.2 on November 9, 2026, together with Claude Mythos 5.2. It is cheaper than Fable 5.1, scores higher on almost every benchmark Anthropic published, and comes with a new fast mode. This guide sums up what changed, what it costs, how it compares, and how to use it for video: in Nano Banana Video Studio, Claude Fable 5.2 writes 3D animations with sound that you render to MP4 in your browser.

claude-fable-5-2(on OpenRouter:anthropic/claude-fable-5.2). - Price: $8 per million input tokens and $40 per million output tokens, down from $10 and $50 for Fable 5.1. Cache reads cost $0.20 per million tokens.
- Fast mode: up to 2.5 times faster on supported platforms, at twice the standard price ($16 / $80).
- Context: 1 million tokens, with up to 128,000 output tokens, according to the OpenRouter listing.

What is new compared with Fable 5.1
Anthropic presents Fable 5.2 as a model for large, loosely defined work: coding across several repositories and big monorepos, testing its own output, and long agentic runs that can coordinate hundreds of subagents. It also reads detailed images and PDFs. Press coverage reports outputs up to 30% faster than the 5.1 generation, before fast mode.
The clearest change is in the numbers Anthropic published at launch (safeguards on, highest effort):
| Benchmark | Fable 5.1 | Fable 5.2 |
|---|---|---|
| FrontierSWE v2 (agentic coding) | 56.3% | 69.9% |
| FrontierCode 2.0 (agentic coding) | 32.4% | 49.1% |
| Humanity's Last Exam (with tools) | 65.6% | 74.2% |
| OSWorld 2.1 (computer use) | 83.5% | 89.3% |
| Chartography (charts, no tools) | 44.8% | 73.4% |
| Remote Labor Index | 17.9% | 41.3% |
These are company-reported results, not independent tests. On the same table, Fable 5.2 is ahead of OpenAI's GPT-6 Astra on agentic coding (69.9% vs 65.5% on FrontierSWE v2) and of Claude Opus 5.5, while Gemini 4 Carbon stays slightly ahead on AutomationBench (53.9% vs 51.4%).
Pricing: cheaper than Fable 5.1 and GPT-6 Astra
At $8 / $40 per million tokens, Fable 5.2 costs 20% less than Fable 5.1. Fortune notes that it also undercuts GPT-6 Astra, listed at $10 / $50, and is far cheaper on cached tokens ($0.20 vs $1 per million). Fast mode doubles the price for up to 2.5 times the speed. US-only inference is billed at 1.1 times the standard rate.
Fable 5.2 vs Mythos 5.2
Both models were announced the same day. Mythos 5.2 is reserved for vetted organizations through Anthropic's Cyber Verification Program and Life Sciences Verification Program. Fable 5.2 is the public model: it carries extra cybersecurity and biology safeguards, and requests that trip them are answered by an earlier Opus model instead. For creative, marketing and coding work, Fable 5.2 is the one you can use today.
Can Claude Fable 5.2 make videos?
Not the way MiniMax H3, Seedance 2.5 or FLUX 3 Max do. Claude models output text and code, never video frames. But code is a very good way to make some videos: a 3D scene written with three.js, with sound designed through Web Audio, can be rendered frame by frame into an MP4. Every move is timed to the frame, text stays sharp, logos are never warped and loops close perfectly. Anthropic itself lists animations and educational videos with sound among Fable 5.2's strengths.
That is the job of the Claude models in Nano Banana Video Studio.
How to use Claude Fable 5.2 in Nano Banana
- Open the Video Studio and go to Create.
- Pick the model Claude Fable 5.2. The standard Claude model is still there for quick drafts.
- Describe the animation: the subject, the camera, the light, the timing and the sound. Choose a duration from 3 to 60 seconds and 720p or 1080p.
- Claude Fable 5.2 writes the scene and its sound. Your browser renders it and encodes an MP4 with sound, which lands on your timeline. If the scene fails to run, it goes back to Claude to be fixed automatically.
- Ask for changes in plain words (“slower camera”, “warmer light”) or edit the code, then combine it with AI video clips on the same timeline.
Credits: a Claude Fable 5.2 animation costs about twice the standard Claude price plus 5 credits: 15 credits for 5 seconds in 720p, 19 in 1080p, 29 for 10 seconds in 1080p. A text change costs 8 credits. If Claude cannot deliver the scene, the credits are refunded.
What to make with it
- Product turntables: a bottle, a sneaker or a phone turning on a pedestal, with light sweeps and reflections.
- Logo and title reveals: particles assembling into a word, kinetic type, a sound hit on the reveal.
- Explainers: a solar system, a heart, a process drawn step by step, with labels and narration-ready timing.
- Data stories: bars that grow to exact values, counters, maps that light up.
- Loops: seamless backgrounds for streams, websites, events and music.
For realistic people, places and physics, keep using a video model such as MiniMax H3 or Seedance 2.5. The best ads often mix both: a lifestyle shot from a video model, then a crisp 3D packshot from Claude Fable 5.2.
Prompt tips for Claude Fable 5.2 animations
- Write a timeline. “At 2 seconds the logo forms, at 4 seconds it glows” gives you exact timing.
- Name the camera. Static, slow push-in, orbit from above: one move per scene reads best.
- Describe the light. Key light side, rim light, a sweep crossing the object, dark or white background.
- Ask for sound. Ambient pad, impacts, ticks, chimes: say when each one happens.
- Give exact values. Numbers, labels and words are drawn exactly as written.

For developers
Use the Claude API with claude-fable-5-2 to plan a campaign and write one prompt per shot, then send each shot to the Nano Banana REST API or let Claude call the Nano Banana MCP server directly from the chat. Both run on your studio credits.
