CLAUDE FABLE 5.1
Anthropic · $10.00/$50.00 per 1M tokens · 1,000,000-token context
Claude Fable 5.1 is Anthropic's model available on Council AI at $10.00 per million input tokens and $50.00 per million output, with a 1,000,000-token context window. Anthropic's most powerful model (released Sep 1, 2026). Improves on Fable 5 across the board at identical pricing, with the largest gains in agentic coding, long-running agentic workflows and knowledge work. 1M context, 128K output. Adaptive thinking only; no sampling params. On Council you do not run it alone: the same prompt goes to up to 10 models from different labs in parallel, and a moderator synthesizes one answer with a consensus score showing where the labs agreed.

Council surfaces it for: reasoning, complex, agents, research.
It has native web search, so it can ground answers in current sources rather than training data alone.
Council does not resell tokens. Every paid plan carries a monthly budget and each model draws against it at cost: $10.00 in / $50.00 out per million tokens for Claude Fable 5.1. Plans start at $19.99/mo (Plus), $39.99/mo (Pro) and $99.99/mo (Ultra, which adds media review, the personal RAG library and MCP server).
If budget is the binding constraint, Claude Opus 5 is the cheaper seat in the lineup at $5.00/$25.00.
A single model — this one included — can be confidently wrong. Council runs Claude Fable 5.1 alongside models from other labs on the same prompt, then scores how much they agreed. High consensus is a signal you can act on the answer; low consensus surfaces the specific point they split on, which is usually the part worth checking yourself.
Other Anthropic models in the lineup: Claude Opus 5, Claude Sonnet 5, Claude Haiku 4.5.
