O1 Pro

by OpenAI

Released 47 days after O3 Mini · All OpenAI releases

O1 Pro is the enhanced variant of OpenAI's O1 reasoning model, dedicating substantially more computation to the reasoning phase. Where standard O1 balances reasoning depth with response speed, O1 Pro prioritizes quality, thinking longer to deliver more reliable answers on the most difficult tasks. It keeps the same 200,000 token context window and accepts text and image input, with support for function calling, structured outputs, and vision. The extra compute shows its value on problems that demand extensive chain-of-thought analysis. O1 Pro suits work where answer quality matters more than turnaround time, such as research, complex engineering decisions, and high-stakes problem-solving. Responses can take longer than standard models as the model thinks through each problem.

Uptime and availability

O1 Pro runs on a single route through the Opper gateway today, so its availability is that provider's availability.

95.97%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. Set up a fallback chain.

Get started

Call O1 Pro through the Opper gateway with one API key. Let your coding agent set it up, or call it directly — Opper 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 Opper for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.OPPER_API_KEY,
baseURL: "https://api.opper.ai/v3/compat",
});
const completion = await client.chat.completions.create({
model: "openai/o1-pro",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
