> Today, we’re introducing the Responses API in public preview, made for building agents on Mistral. 
> 
> Each response returns the model’s answer, its reasoning and its tool calls as separate items, so your app can handle every step more easily than with Chat Completions. 
> 
> It works with all chat models hosted by Mistral, including Large 4.
