Available Models

Chat Models

CohereProvider::MODEL_COMMAND_A_PLUS      // 'command-a-plus-05-2026' (default)
CohereProvider::MODEL_COMMAND_A           // 'command-a-03-2025'
CohereProvider::MODEL_COMMAND_A_REASONING // 'command-a-reasoning-08-2025'
CohereProvider::MODEL_COMMAND_R7B         // 'command-r7b-12-2024'

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.

Embedding Models

CohereProvider::MODEL_EMBED_ENGLISH       // 'embed-english-v3.0'
CohereProvider::MODEL_EMBED_MULTILINGUAL  // 'embed-multilingual-v3.0'
