Chat（Mistral）

POST

/chat/completions

A chat model takes a series of messages as input and then returns model-generated messages as output. Although the chat format is designed to facilitate multi-turn conversations, it is equally useful for single-turn tasks without any dialogue.

Note: This model has limited support for Chinese. Please try to ask questions in English whenever possible.

Supports the following models：

devstral-small-2505
Mixtral-8x7B
Mistral-Large-2411
mistral-medium-latest
