DEPRECATED 2026-02-27 with a stated retirement of 2026-03-31 -> Mistral Medium 3.5. That date has passed, but Mistral still lists the model as deprecated rather than retired and still prices it publicly, so we record the status Mistral states rather than inferring a retirement it has not declared. Price and context from the official docs model schema, corroborated by mistral.ai/pricing/api. Max output and knowledge cutoff not published -> null.
