Mistral Large 4 public preview and open-weights plan
What happened
On October 6, 2026 at 20:00, Mistral AI announced a public preview of its natively multimodal model Mistral Large 4, available to try through the Mistral Studio API, with weights planned for release at the end of the month. At 21:06 the model hit the Hacker News front page. A 21:15 report said it uses a fine-grained MoE architecture with 49B activated parameters and a 1.6B vision encoder. An earlier report said weights were already open and total parameters were 1.05T; a later 21:29 report said weights are planned for release at the end of October and total parameters are 1T, matching the timing in the first-hand announcement. Mistral says it reaches SOTA on cyberdefense, manufacturing and financial workloads, and that its visual grounding beats closed frontier models. A 22:02 report added OpenRouter beta details: 512K context, up to 256K output, and half price for the first two weeks at $0.68 per million input tokens, $2.09 output and $0.07 cached.
