Our take
Written Aug 2, 2026Claude Fable Latest is Anthropic's newest proprietary model, released in June 2026, which can handle up to one million tokens in a single request and accepts text, images and files. It is available only through OpenRouter with no alternative hosts or pricing options currently tracked.
Choose this when you need Anthropic's latest proprietary model with very long context, or when your workflow mixes text, images and files into a single text output. Use it if OpenRouter is already your preferred provider. Skip it if cost matters — the output rate is steep with no cheaper alternatives — or if you need verified quality scores, measured throughput, or provider choice.
The case for it
- One million tokens in a single request, a very large disclosed limit.
- Multimodal input: accepts text, images and files alongside that long context.
The case against it
- Output pricing is steep, with no cheaper alternative offers in our data.
- No measured quality scores available — chat, reasoning, coding and safety benchmarks are all unverified in our data.
- Only one tracked offer, so there is no price competition or alternative hosting.
How good is it?
We hold no score for this model.
We look for every model we track on every board we watch, and none of them has turned up Claude Fable Latest — so there is no intelligence, coding, agentic or writing score to show you, not a low one, none.
