Claude Fable 5.2

Claude Fable 5.2 is the expected successor to Fable 5.1, Anthropic's top tier. Expected soon, and Magnus adds it to the model roster the day the API is live.

Status

Expected soon. Anthropic has not announced a release date. Magnus already runs Fable 5.1 through the same API, so Fable 5.2 appears in the model picker automatically once it is generally available.

What to expect

Fable is Anthropic's tier for demanding reasoning and long-horizon agentic work, and Fable 5.2 is expected to continue the line. Benchmarks will be added here when Anthropic publishes them - we do not reprint pre-launch rumors as numbers.

  • Until it lands, Claude Fable 5.1 (5 credits) is the strongest brain you can put behind Magnus.
  • The marketing teaser lives at getmagnus.co/models/claude-fable-5-2.

Availability on Magnus

As a Claude model it will run the full toolset - integrations, live web search, native PDF reading - from day one. Credit pricing on the All-inclusive plan will be set from the published API price at launch.

  1. Open Settings and pick Claude as your provider (it is included in your plan).
  2. When Fable 5.2 appears in the model picker, select it - existing agents keep their history when you switch models.
  3. Watch What's New and the changelog - every roster addition is announced there.
