Devstral 2

Mistral AI’s Devstral the listed price is a 123B-parameter dense transformer designed for agentic software development. Its central strength is codebase exploration: it can use tools to follow framework dependencies, detect failures, and retry work with corrections, making it suitable for autonomous coding workflows and complex debugging sessions.

The model is intended to coordinate edits across multiple files while retaining architectural context, a useful fit for legacy modernization and larger enterprise codebases. Open weights under a modified MIT license also support fine-tuning toward particular programming languages or internal repository structures.
