# Mistral Devstral 2 — deprecation status

> Yes — Devstral 2 is retired. Mistral deprecated it on May 22, 2026 and shut it down on July 31, 2026; API requests to it now fail. The recommended replacement is Mistral Medium 3.5.

Mistral's agentic coding model, built for driving a codebase through a tool loop rather than completing a line in an editor. Devstral 2 lasted seven months. Mistral retired the whole Devstral line into Medium 3.5 in mid-2026, which is the clearest example of its strategy of collapsing specialist ids into one general model.
