Ministral 3 3B

Ministral 3 3B brings text and image input to the smallest model in the Ministral 3 family. The name refers to a 3.4B language model paired with a 0.4B vision encoder. It has API access and Apache 2.0 weights for local extraction, captions and short responses.

Choose the checkpoint and precision

The FP8 Instruct checkpoint is documented as fitting in 8GB of VRAM. Mistral also publishes Base and Reasoning versions. The card recommends a small, clearly defined tool set. This is a useful constraint for a model that must choose between actions on a limited device.Ministral 3 3B Instruct model card

Use the instruction API

The hosted model identifier is ministral-3b-2512. Its model page lists function calling, structured output, document questions, prefix completion and batch processing. The Base and Reasoning names here identify published weight variants; they are not additional confirmed serverless aliases.Ministral 3 3B API model page

Check the device workload

Practical guidance. Start with narrow requests, such as extracting a few fields or describing one image. Define the output format and measure missed fields or incorrect tool choices. Escalation to a larger model should follow those observed errors. A small language component does not make every long-context or vision request inexpensive.
