When to use

  • Deep reasoning — pair with thinking: { enabled, budget_tokens: 1024+ } for the extended chain-of-thought.
  • Long-document QA — legal/regulatory text and multi-doc synthesis within 200K.
  • Web search — research-style queries that need fresh facts.
When not to use:
  • New flagship work — claude-opus-4-8 is the current Opus and supersedes this model.
  • Default chat — claude-sonnet-4-6 is one-fifth the cost at the same 200K context.
  • High-volume classification — claude-haiku-4-5 is twenty times cheaper.
