What changed
Mistral announced a public API preview of Large 4, a multimodal model emphasizing coding and agentic work. The launch says downloadable weights will follow later in October. Performance statements in the announcement are Mistral’s own claims.
The everyday takeaway
A preview is a chance to evaluate, not a reason to redesign your whole setup. Home users should wait for an actual download, a license, and realistic hardware guidance before planning a local install.
What we have verified
Mistral’s October 6 announcement and current changelog both describe a public preview, with weights still promised for later in October. The linked external evaluation covers its own preview configuration. We have not downloaded or benchmarked Large 4.
A second perspective
The evaluator compares capability and cost per task, and explicitly labels the release a preview with weights pending.
