Anthropic: Claude Fable 5.2

Coming soon

Anthropic's newest Fable, built for demanding reasoning and long-horizon agent work, and cheaper than Fable 5.1. It isn't on TeamoRouter yet: when it launches, your key works as is and you only switch the model ID. Use Claude Fable 5.1 or Opus 5.5 in the meantime.

Pay as you go from $5 — card, Alipay or USDT.

What we know

  • Released November 9, 2026 on the Claude API, Claude Platform on AWS and Google Cloud. Model ID: claude-fable-5-2.
  • 1M-token context, up to 128k output tokens, always-on adaptive thinking. Official price: $8 input / $40 output per million tokens (Fable 5.1: $10 / $50).
  • Breaking changes from Fable 5.1: editing earlier turns invalidates its thinking blocks on every account, and only Fable 5.2 and Mythos 5.2 can read its thinking. Claude Code builds requests that already follow these rules.

Until it's on TeamoRouter, use these two

Same key, just switch the model ID.
