Backport: fix(anthropic): allow both temperature and topP for non-Anthropic models#14056
Conversation
…hropic models The temperature/topP mutual exclusivity check was applied to all models using the @ai-sdk/anthropic provider, but providers like Minimax that use the Anthropic-compatible API may require both parameters. - Introduce `isAnthropicModel` derived from `isKnownModel` or `claude-` prefix - Only enforce temperature/topP mutual exclusivity for Anthropic models Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Background
Port of #14052 to
main.The
@ai-sdk/anthropicprovider enforces temperature/topP mutual exclusivity for all models, matching a constraint in the Anthropic API. However, providers like Minimax use the Anthropic-compatible API endpoint with non-Anthropic models (e.g.MiniMax-M2.7) that require bothtemperatureandtop_pto be set simultaneously.Summary
