Adapt now draws on Anthropic's newest models, Sonnet 5 and Fable 5, alongside the rest of its frontier lineup. As always, you don't pick a model — Adapt automatically routes each task to the best-in-class model for the job, balancing cost and complexity while prioritizing output quality.

What changed

Sonnet 5 and Fable 5 are live across Adapt today, joining the models Adaptive Intelligence already routes across. Nothing changes about how you use Adapt — routing stays automatic.

Why it matters

  • Access to the latest frontier models. Sonnet 5 and Fable 5 join Adapt's lineup the moment they're ready for production use.
  • No knobs to turn. Adapt decides which model handles which task automatically — you just ask, the same way you always have.
  • Quality first. Routing is tuned to prioritize accurate, high-quality output, reaching for the most capable available intelligence when a task calls for it.

See Adaptive Intelligence for how Adapt matches intelligence to the task.
