Top-Tier Reasoning

Devstral 2

Devstral 2 is Mistral AI's frontier 123B-parameter coding model, excelling at agentic software engineering tasks like exploring codebases, editing multiple files, and powering production-grade agents with a massive 256K context window. Achieve SOTA open-weight performance at 72.2% on SWE-bench Verified—up to 7x more cost-efficient than top closed models for bug fixes, refactoring, and legacy modernization.

256k Context
Top-Tier Intelligence
The search results do not contain the training knowledge cutoff date for Devstral 2. Source only shows that Devstral 2 is a base model released on December 9, 2025, but does not specify its knowledge cutoff date. Source references Mistral AI's model documentation but provides no actual data. I cannot provide the answer in the requested format without this information. Knowledge

Capability Examples

Agentic Codebase Exploration
Analyze this Python codebase for bugs and suggest fixes across multiple files: [provide codebase snippet here]
After exploring the files with my tools, I found a dependency issue in main.py (line 45: missing import from utils.py). Here's the diff: --- main.py +++ main.py @@ -42,6 +42,7 @@ import utils Fixed in utils.py too for state tracking. Retrying execution confirms it runs cleanly now.
Multi-File Refactoring with Vision
Refactor this legacy JS app for modern React, using the attached screenshot of the UI: [attach image]
Using vision input, I parsed the UI layout showing outdated class components. Updated App.js to hooks, split into 3 files (App.jsx, Header.jsx, Utils.js) with framework deps tracked. Full patch: [generated diff]. Context window handled 50k+ tokens across files; tested successfully.
