O3 Mini

by OpenAI

Released 57 days after O1 Β· All OpenAI releases

O3 Mini is OpenAI's lighter-weight reasoning model, delivering strong reasoning at lower cost than full O3. Released January 31, 2025, it is optimized for science, mathematics, and coding challenges. The model exposes adjustable reasoning effort across three levels, low, medium, and high, so developers can tune how much computation each request spends: low for latency-sensitive tasks, medium for balanced performance, and high for harder problems that need deeper reasoning. O3 Mini supports structured outputs, function calling, and streaming, with a 200,000 token context window and up to 100,000 output tokens. It is text-only without vision, positioning it as an efficient option for reasoning workloads that do not need image input.

Uptime and availability

O3 Mini runs on a single route through the qynio gateway today, so its availability is that provider's availability.

96.06%route uptime, last 30 days
Single route, no failover target within this model.

Name a second model in the same request and the gateway tries it on retriable errors, so a busy hour never has to reach your users. .

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. See uptime for every provider qynio monitors.

Data handling per route

Each route hosting O3 Mini has its own privacy posture, residency, and no-KYC terms. Postures are maintained by qynio with a last-verification timestamp.

Get started

Call O3 Mini through the qynio gateway with one API key. Let your coding agent set it up, or call it directly β€” qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.QYN_API_KEY,
baseURL: "https://api.qyn.io/v3/compat",
});
const completion = await client.chat.completions.create({
model: "openai/o3-mini",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
