Mistral Drops Large 4, a 1 Trillion Parameter Open Coding Agent

Mistral has released the open weights for Mistral Large 4, a 1-trillion-parameter model positioned as a coding agent. It reportedly leads open-weight coding benchmarks, accepts multimodal input, and includes cyberdefense tuning. That matters because developers gain a frontier-class open coding model they can run and build on, rather than only reaching one through an API.
