Ministral 3B
Ministral 3B by Mistral AI: $0.1 input and $0.1 output per 1M tokens, 131K context. Call it through the odnoga LLM gateway.
Ministral 3B is served by Mistral AI and called through odnoga with the same OpenAI-compatible request shape as every other model in the catalog. It supports tool and function calling. It can be forced to return structured JSON. Its 131K-token context window sets how much input you can send in one request.

Vendor cost is the list price per million tokens as recorded in the odnoga catalog; your price applies your plan margin with the same formula that bills every request — see pricing. Pricing
Call it through odnoga
const res = await fetch("https://api.odnoga.com/v1/chat/completions", {
method: "POST",
headers: {
Authorization: `Bearer ${process.env.ODNOGA_API_KEY}`,
"Content-Type": "application/json",
},
body: JSON.stringify({
model: "ministral-3b-latest",
messages: [{ role: "user", content: "Hello" }],
}),
});
Same request shape for every vendor in the catalog — swap the model id and odnoga handles keys, routing, limits and cost accounting.
How to use Ministral 3B
Derived from the odnoga catalog record for this model.
Best for
- High-volume, latency-sensitive calls: classification, extraction, routing, short rewrites and summaries.
- Agents and workflows that call your own functions, because the model supports tool calling.
- Machine-readable output you can write straight into a database, using enforced JSON.
- User-facing chat where partial output should appear while the model is still writing.
Not the right pick when
- Anything that needs to read an image — this model takes text only.
- Anything where a wrong answer is costly without a human check — no model in the catalog removes that requirement.
Practical tips through odnoga
- 01Pin the model id in a managed prompt version, so a model swap is a version change you can compare and roll back, not an edit in application code.
- 02Compare it against 2–8 other models on the same frozen test cases in the evaluation laboratory before you make it the production default.
- 03For repeated identical deterministic calls, odnoga answer reuse returns the stored answer and bills no vendor tokens — turn it off for creative output.
- 04Ask for JSON through the response format rather than in the prompt text — the schema is enforced instead of suggested.
- 05Set a fallback model on the route so a vendor incident degrades quality instead of returning an error, and a per-tenant budget so one caller cannot spend the month.
What a month costs
1,000 calls a month, 10,000 input tokens and 2,000 output tokens each, at your Free price (vendor cost +7%):
| Input (10M tokens) | $1.08 |
|---|---|
| Output (2M tokens) | $0.215 |
| Your cost per month on Free | $1.29 |
Vendor list cost $1.20 + odnoga margin $0.090 (+7%). Cached input or answer reuse lowers it; odnoga records both numbers per request.

Questions
- How much does Ministral 3B cost per 1M tokens?
- Mistral AI lists $0.1 / $0.1 per 1M input / output tokens in the odnoga catalog. Through odnoga you pay that vendor price plus your plan margin, and every request is recorded with both numbers.
- What is Ministral 3B best for?
- High-volume, latency-sensitive calls: classification, extraction, routing, short rewrites and summaries. Agents and workflows that call your own functions, because the model supports tool calling. Machine-readable output you can write straight into a database, using enforced JSON.
- Can I switch to Ministral 3B without changing my code?
- Yes. odnoga exposes one OpenAI-compatible endpoint, so switching means sending "ministral-3b-latest" as the model id — or changing it in the managed prompt version, with no application deploy.
- How large is the Ministral 3B context window?
- 131K tokens of input, with up to 8K tokens of output per response.
