# Mistral Medium 3 — deprecation status

> Yes — Mistral deprecated Mistral Medium 3 on May 22, 2026 and shuts it down on August 31, 2026 (in 28 days). The recommended replacement is Mistral Medium 3.5.

The model that reintroduced a middle tier to Mistral's API after two years of only Small and Large, and the first sign that Large was being quietly demoted. It shares its 31 August 2026 shutdown with Medium 3.1, so both generations of the id go dark on the same day rather than the older one leaving first.
