Devstral 2

by Mistral

Devstral 2 is Mistral's December 2025 code agents model, built for end-to-end software engineering automation. The 123B-parameter dense transformer scores 72.2% on SWE-bench Verified and is positioned by Mistral as up to 7x more cost-efficient than Claude Sonnet on real-world tasks. The model excels at exploring codebases and orchestrating changes across multiple files, tracking framework dependencies, detecting failures, and retrying with corrections. It handles refactoring, bug fixing, and legacy modernization through natural language while maintaining architectural context. Devstral 2 is released under a modified MIT license and ships with a 256k token context window. It is complemented by Mistral Vibe, an open-source CLI for terminal-based code automation, letting agents and developers explore, modify, and execute changes across entire codebases.

Single route, no failover target within this model.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. .

Get started

Call Devstral 2 through the qynio gateway with one API key. Let your coding agent set it up, or call it directly β€” qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.QYN_API_KEY,
baseURL: "https://api.qyn.io/v3/compat",
});
const completion = await client.chat.completions.create({
model: "mistral/devstral-2512",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
