List every provider in the models.dev catalog (e.g. anthropic, openai, google) with its model count. Use this to see what's available before narrowing with find_models.

Search and filter models across all providers by name, provider, capability, context window, or price. Returns a compact summary per model; use get_model for full details on one.

Fetch full metadata for one model. Accepts 'provider/model' (preferred, e.g. 'anthropic/claude-sonnet-4-5') or a bare model id if unambiguous across providers.

Diff 2-6 models side by side on pricing, context window, and capabilities. Accepts 'provider/model' ids, or bare model ids when unambiguous across providers. Ids resolving to the same model are compared once.

Force a fresh fetch of the models.dev catalog, bypassing the in-memory cache. Use if you suspect the data is stale. If the refetch fails, the last good catalog keeps being served and servedStale is reported as true.

Estimate the USD cost of a request to one model from its published per-million-token rates. Use get_model first if you need to pick an id.

Rank models by one criterion: cheapest input/output price per million tokens, largest context window, most context per input dollar, or newest release. Supports the same filters as find_models.

Fetch metadata for one provider: display name, AI SDK package name, API base URL, docs link, and a compact list of its models. Accepts the provider id ('anthropic') or display name ('Anthropic'). Use get_model for full per-model detail.
