When was O3 released?

OpenAI released O3 on 16 Apr 2025. It is available through the qynio gateway.

Does O3 support zero data retention?

Not by default. See the per-route data-handling section for each route's logging stance and retention window.

O3 runs on US hosting routes through the qynio gateway.

Is O3 trained on prompts and outputs?

No. Every hosting route for O3 is configured so customer prompts and outputs are not used to train models by default.

Is a no-KYC deposit available for O3?

Yes. A no-KYC Data Processing Agreement is available on at least one route serving O3. Contact hello@qyn.io to receive it.

O3

by OpenAI

All OpenAI releases

O3 is OpenAI's advanced reasoning model, pairing stronger performance with broader tool use. In expert evaluations it makes about 20 percent fewer major errors than O1 on difficult real-world tasks, with particular gains in programming, business and consulting work, and creative ideation. The model thinks before responding and can use tools within a single reasoning session, searching the web, analyzing files with Python, reasoning over visual inputs, and generating images. It accepts text and image input, with a 200,000 token context window and up to 100,000 output tokens. O3 supports streaming, function calling, and structured outputs through the Chat Completions and Responses APIs, making it suitable for complex multi-step problems that span code, analysis, and visual reasoning.

Uptime and availability

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

Get started

Call O3 through the qynio gateway with one API key. Let your coding agent set it up, or call it directly — 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.
