Mistral Small 4 unifies instruct, reasoning, and coding in one open model
AIMistral Small 4 combines instruct, reasoning, and Devstral capabilities in one multimodal model with 119B total parameters, 6.5B active per token, and a 256k context window. The source reports a 40% reduction in latency-optimized end-to-end completion time and 3x more requests per second in throughput-optimized setups versus Mistral Small 3. It is released under Apache 2.0 and supports reasoning mode toggling per request.
Why it matters: The source lists architecture, context length, and mode-switching controls, letting readers compare this release's design with earlier Mistral Small models.
