Mistral Large 4: preview API, weights announced for late October
Mistral's multimodal model targets code, agents and professional uses; weights are not yet delivered to the source.
Public preview
Facts, analysis and limits
Verified facts
- ML4 is described as a one-trillion-parameter model with 52 billion active parameters.
- A public preview API is available in Mistral Studio.
- Weights are promised by the end of the month, during a red teaming phase.
- Mistral states that training and the preview service use its own European infrastructure.
What changes
A European offer seeks to combine capacity, controlled infrastructure and future distribution of weights; the preview is not yet an autonomous deployment.
Practical implication
Judge the preview on useful use and wait for weights and license before concluding on actual autonomy.
Availability
Preview served on European infrastructure according to Mistral; no Belgian exclusion mentioned. Check region, contract and account availability.
Limits and uncertainty
Do not write "weight available": the October 6th post announces them for the end of the month. Benchmarks not reverified independently.
