Available Models

Chat Models

CohereProvider::MODEL_COMMAND_A_PLUS      // 'command-a-plus-05-2026' (default)

The MODEL_COMMAND, MODEL_COMMAND_R and MODEL_COMMAND_R_PLUS constants are still shipped but deprecated: all three were deprecated on 15 September 2025, and the two oldest predate command-r7b, so they reject forced tool choice.
