anthropic

Current Anthropic Claude models.

These models choose their own sampling: the API rejects temperature, top_p and top_k, so this builder doesn’t offer them. Thinking is adaptive; set its depth with reasoning_effort (sent as output_config.effort).

For older Claude models that still take sampling parameters, see glean/models/anthropic_sampling.

Types

Claude

opaque </>

A Claude model builder. Pick a model with one of the constructors (or custom), chain setters, then call build().
