Mistral Small 3.1 (25.03)

Mistral Small 3.1 (25.03) is a text generation model developed by Mistral, released in March 2025. It features a 128,000-token context window, multimodal understanding, and support for dozens of spoken languages alongside more than 80 coding languages. The model is designed to run on a single node, making it practical for deployment without distributed infrastructure. This version introduces improved text performance and expanded context handling compared to earlier Mistral Small releases. At an inference speed of approximately 150 tokens per second, it is suited for tasks that require both throughput and long-context processing, such as document analysis, multilingual applications, and code generation. Its combination of broad language coverage and single-node efficiency makes it a practical choice for developers building production applications with constrained compute budgets.
