Mistral: Devstral 2 2512

Devstral 2 is a state-of-the-art open-source model developed by Mistral AI, specifically designed for agentic coding. This powerful 123B-parameter dense transformer model boasts an impressive 256K context window, enabling it to handle extensive codebases with remarkable efficiency. It's engineered to explore complex code structures, orchestrate modifications across numerous files, and maintain architecture-level context throughout the process. This model is adept at tracking framework dependencies, detecting failures, and autonomously retrying with corrections, making it an invaluable tool for challenging tasks like bug fixing and modernizing legacy systems. Devstral 2 can be fine-tuned to prioritize specific programming languages or optimized for large enterprise codebases. It is available under a modified MIT license. With a context window of 262K tokens and a max output of 4K tokens, it offers robust performance. Pricing is set at $0.05 per 1M input tokens and $0.22 per 1M output tokens, accessible via the STARTER tier.
