Mistral reports 1.05T total and 49B active parameters, plus a 1.6B vision encoder. The vendor describes this public preview as open-weight, but its checkpoint page currently supplies no weight download or license, and no Large 4 checkpoint was found in the official Hugging Face registry. Classified as API-only until the exact weights and license can be verified. The OpenRouter route exposes 524,288 context tokens and 262,144 completion tokens, with tools and structured outputs but no configurable reasoning parameter.
