Ministral 14B
Mistral AI's compact Ministral model via the Vercel AI Gateway: efficient text and vision at a 256k context window with flat, low pricing and function calling. Available at the base tier. Uses 1 base request per send before length multipliers. Supports image input. Does not support web search.
You always get the exact model you pick — we never silently route you to another.
About Ministral 14B
Ministral 14B is Mistral's compact, efficiency-minded model, and on just4o.chat it runs through the Vercel AI Gateway as mistral/ministral-14b. It is built to be fast and inexpensive while still handling both text and image input — a rare combination at its flat $0.20-per-million price for input and output alike. That symmetry makes its cost easy to reason about, and at the base tier it bills just 1 base request per send before length multipliers, so it is a natural choice for high-throughput tasks, lightweight assistants, and anywhere predictable low cost matters. A 256k-token context window is generous for a model this size, and function calling is supported for simple tool use. The caveats are what you would expect from a small model: no native web search, and it will not match the reasoning depth of Mistral Large 3, Medium 3.5, or Magistral on hard problems. For quick multimodal tasks, classification, and cost-efficient everyday work, it punches above its size.
Best for
- High-volume, cost-sensitive tasks where flat $0.20 pricing is attractive
- Lightweight multimodal work — quick reasoning over text plus images
- Classification, extraction, and routing at scale
- Simple tool-using assistants with function calling
- Long-context tasks up to 256k tokens on a small-model budget

Frequently asked questions
Yes. Despite its small size, it accepts both text and images, making it a budget-friendly multimodal option.
A flat $0.20 per million tokens for both input and output at provider reference pricing. On just4o.chat it is a base model that uses just 1 base request per send before length multipliers.
Through the Vercel AI Gateway's OpenAI-compatible endpoint under the mistral/ministral-14b route. Mistral applies zero data retention to gateway traffic.
256,000 tokens, generous for a compact model.
No native web search, and as a small model it does not match the reasoning depth of Mistral's larger models on complex problems. It shines on speed, cost, and lightweight multimodal tasks.
