Core Capabilities of Mistral Small 3.1 24B
Up to 128K tokens of context
Keep long conversations, large documents and sizeable code in a single request, so the model can reason over the full material instead of fragments.
Understands images
Besides text, Mistral Small 3.1 24B accepts images as input, so a single request can combine instructions with visual or other media.
Function calling
Mistral Small 3.1 24B supports tool (function) calling: describe your functions in the request and the model returns structured calls your code can run — the basis for agents and integrations.
Structured outputs
Ask for JSON that follows a schema (response_format), which makes extraction, classification and system integrations more reliable.
