About
Mistral's own platform hosts their Large, Medium, Small, and Codestral models with an Experiment free mode that needs no credit card. The API is OpenAI-compatible, so your agent code usually needs one URL change, and the models have native function calling for tool use. Heads up: free-tier data is used for training by default, but you can opt out in Admin settings.
Details
