🔖 Feature description

Devstral is an agentic LLM for software engineering tasks built under a collaboration between Mistral AI and All Hands AI 🙌. Devstral excels at using tools to explore codebases, editing multiple files and power software engineering agents. The model achieves remarkable performance on SWE-bench which positionates it as the #1 open source model on this benchmark. It is finetuned from Mistral-Small-3.1, therefore it has a long context window of up to 128k tokens. As a coding agent, Devstral is text-only and before fine-tuning from Mistral-Small-3.1 the vision encoder was removed. https://huggingface.co/mistralai/Devstral-Small-2505

Devstral is fine-tuned from Mistral‑Small‑3.1, but due to certain modifications, it is currently not compatible with Axolotl.

✔️ Solution

Support Devstral by inheriting from Mistral‑Small‑3.1.
