Strengths
Mistral's coding-specialized model, purpose-built for software development rather than general chat, with a 262,144-token context window and up to 8,192 output tokens.
Strong at writing new code and reviewing existing code, trained specifically on software-engineering tasks across many languages and frameworks.
Tuned for finding and fixing bugs and restructuring code while preserving behavior, the kind of iterative work coding agents rely on.
A 262,144-token context window holds large multi-file code spans at once, so it can reason across a sizeable portion of a repository in a single request.

Devstral 2 API — pricing, context window & access
Devstral 2 is Mistral's coding-specialized model, purpose-built for software development with strong code generation, debugging, and refactoring. It carries a 262,144-token context window and up to 8,192 output tokens, focused squarely on engineering work.
YepAPI serves Devstral 2 over an OpenAI-compatible endpoint with one key that also reaches Mistral Medium 3.5, Mistral Small 4, Claude, Gemini, Grok, Qwen, and Perplexity Sonar, plus SEO, SERP, and scraping APIs.
What is Devstral 2?
Devstral 2 is Mistral's developer-focused model, specialized for software engineering rather than general-purpose chat. It is tuned for the core loop of coding work — generating code, reviewing it, finding and fixing bugs, and refactoring while keeping behavior intact — across many languages and frameworks. It carries a 262,144-token context window, enough to hold large multi-file spans of a codebase, and returns up to 8,192 output tokens. For agentic coding tools and developer assistants, it offers focused coding ability at a low price.
Build with Devstral 2 via YepAPI
Call Devstral 2 through YepAPI's OpenAI-compatible /v1/ai/chat endpoint with the model set to devstral-2512. Existing OpenAI SDK code works after a base-URL and model-name change. A common setup routes coding requests to Devstral 2 and general chat to Mistral Small or Claude — a one-string switch. The same key reaches every model plus SEO, SERP, and scraping endpoints, so a coding agent and its tools share one integration.
Devstral 2 API pricing — $0.56 / $2.80 per 1M tokens
Devstral 2 costs $0.56 per 1M input tokens and $2.80 per 1M output tokens on YepAPI. For a dedicated coding model with a 256K-token window those rates are very low, which matters for agentic workflows that read large code context and iterate over many turns. The cheap input rate especially helps when you feed substantial repository context per request. Billing is per token with no minimums.
Devstral 2 for coding agents and developer tools
Devstral 2 is built for the work it names: powering coding agents, IDE assistants, automated code review, and refactoring pipelines. Its specialization means it focuses compute on engineering quality rather than broad chat, and its 256K-token window lets an agent load several files at once to reason across them. For developers who want strong, affordable coding throughput, it is a focused alternative to general flagships.
