Introducing Mistral Small 4

Mistral Small 4 unifies chat, reasoning, multimodal input, and coding-agent capabilities in an Apache 2.0 model.
Mistral AI introduced Mistral Small 4 as the next major release in the Mistral Small family. It combines reasoning, multimodal, and agentic coding capabilities into one open model with configurable reasoning effort. The model uses a MoE architecture, supports a 256k context window and text-image inputs, and is available through Mistral API, AI Studio, Hugging Face, NVIDIA NIM, and common inference stacks.
On March 16, 2026, Mistral AI released Mistral Small 4, the next major version of the Mistral Small family. The company describes it as the first product to unify the capabilities of Mistral's flagship models into a single model: including Magistral's reasoning capabilities, Pixtral's multimodal capabilities, and Devstral's agentic code development capabilities. For developers and enterprises, the key point is not just that the model is stronger, but that whereas previously you might have needed to switch between a fast instruction model, a reasoning model, a multimodal assistant, or a coding agent, you can now handle more types of tasks with a single model.
