Claims

  1. Devstral is an agentic language model for software engineering built as a collaboration between Mistral AI and All Hands AI and released under the Apache 2.0 licence. Mistral reports it scoring 46.8% on SWE-Bench Verified when evaluated inside the OpenHands scaffold, exceeding much larger models such as DeepSeek-V3-0324 (671 billion parameters) and Qwen3 232B-A22B under the same scaffold. Mistral states the model is light enough to run on a single RTX 4090 or a Mac with 32 GB of RAM, and describes it as a research preview.
    "Devstral achieves a score of 46.8% on SWE-Bench Verified ... light enough to run on a single RTX 4090 or a Mac with 32GB RAM ... Devstral is a research preview"
