Other 2026 releases on the news page: Leanstral 1.5 (2026-07-02) and Robostral Navigate (2026-07-08). The model docs also list Mistral Embed, Codestral Embed, Shieldstral 1.0 and third-party GLM 5.3 (GLM-5 series). Mistral announced a Series D of EUR 3B at a EUR 21B+ post-money valuation on 2026-09-08 (its news page; a reported Samsung stake is unconfirmed and not stated here). The docs list no model released after Medium 3.5 (the audit’s “August release” was not found), so Medium 3.5 is the latest flagship. Prompt format of older Instruct models: mistral-prompt-template.
