supports_sampling_params(model)

Whether a Claude model accepts the temperature, top_p, and top_k sampling parameters.

Support is derived from the Claude model family and version embedded in model rather than a hardcoded model id, so every model in an affected family at or above the deprecating version (for example every Opus release from 4.7 onward, including major-only ids like claude-opus-5) is covered without a per-model change. A model whose minor version is absent is treated as .0.
