# Mistral Medium 1.0 — deprecation status

> Yes — Mistral Medium 1.0 is retired. Mistral deprecated it on November 30, 2024 and shut it down on June 16, 2025; API requests to it now fail. The recommended replacement is Mistral Medium 3.5.

The oldest id in Mistral's table, from December 2023, and a model the company never published anything about - no weights, no paper, no architecture. It leaked to the internet as "Miqu" in early 2024 and was widely believed to be a Llama 2 70B fine-tune, which Mistral's CEO more or less confirmed.
