Mistral Large 4
A versatile model, balanced across most use cases.
Overview
Mistral Large 4, nicknamed 'Le Chonk', is Mistral AI's new MoE generalist model (1000 billion parameters), unveiled on October 6, 2026 in restricted API access. Aimed at agentic and enterprise use cases, it's priced at $1.36 / $4.18 per million tokens, but its context window hasn't been disclosed yet and its licence is still unknown - open weights are only promised for late October. Being built by a French vendor is a reassuring signal for European compliance, though as long as the model is only served via hosted API, actual data residency will depend on hosting terms that remain to be confirmed.

Three independent measures
What people prefer, what the model can do, what the market uses. Each source has its biases and none is enough on its own: we show them side by side, never blended.
Strengths

Limitations

Who is it for
- you handle sensitive data with no EU option
Ideal use cases
- Enterprise conversational agents
- Multilingual assistant prototypes
- Early API evaluation
- Tracking European model progress
