Mistral AI Launches 1-trillion Parameter Open-Weight Model Mistral Large 4
Something you can actually use or run today.
On October 29, 2026, Mistral AI released the weights for 'Mistral Large 4,' a 1-trillion parameter multimodal model.
It is the first open-weight model of this scale to truly challenge the dominance of GPT-6 and Gemini 4 at the highest reasoning tiers.
Mistral has reclaimed the open-source throne with 'Le Chonk.' A 1T parameter model being available for private hosting changes the risk-reward calculation for enterprises who were hesitant to send sensitive data to OpenAI.
