Next open-weight MoE family (early access)
CEO Arthur Mensch says a 'fat but sparse' open-weight MoE family enters partner early access in July, with broader release later in summer.
Mensch said Mistral has narrowed the gap but does not yet own the best models. No parameter count, benchmarks, license or date were disclosed. The family is larger in total parameters than Large 3 (675B). Backed by a reported EUR 4B data-center build in France and Sweden.

Single secondary source (TechTimes citing a LinkedIn essay by Mensch). As of 2026-10-04 I found no public release or model name for this family; Mistral's 2026-09-08 funding post (EUR 3B, led by Samsung, over EUR 21B valuation) did not mention it.
