Mistral Medium 3.5 hits 77.6% on SWE-Bench Verified and becomes the Le Chat default.
Story
On June 24 Mistral set Medium 3.5 as the default in Le Chat, reporting 77.6% on SWE-Bench Verified, ahead of Devstral 2 (Mistral via Releasebot). A European, open-leaning option clearing roughly 78% on SWE-Bench Verified is a credible alternative to US frontier coding models, especially stacked with the scoped-key Connectors. The agentic-coding field is getting genuinely crowded at the "good enough" tier, which is great for builders and rough for anyone trying to charge frontier prices.
