When was O1 released?

OpenAI released O1 on 5 Dec 2024. It is available through the Opper gateway.

Does O1 support zero data retention?

With abuse monitoring, yes. On OpenAI through the Opper gateway, prompts and outputs are not used for training and are kept only for abuse monitoring, for up to 30 days.

O1 runs on US hosting routes through the Opper gateway.

Is O1 trained on prompts and outputs?

No. Every hosting route for O1 is configured so customer prompts and outputs are not used to train models by default.

Is a GDPR DPA available for O1?

Yes. A GDPR Data Processing Agreement is available on at least one route serving O1. Contact hello@opper.ai to receive it.

O1

by OpenAI

Released 15 days after GPT-4o · All OpenAI releases

O1 is OpenAI's reasoning-focused model, trained with reinforcement learning to reason deeply before responding. It produces a long internal chain of thought, spending substantial computation on problem-solving rather than immediate generation. The model accepts text and image input and produces text output, with up to 100,000 output tokens. It supports function calling, structured outputs, streaming, and the Responses API for applications that need extended reasoning. O1 is particularly strong in physics, chemistry, biology, mathematics, and software engineering, where multi-step reasoning provides the greatest advantage. With a 200,000 token context window, it handles substantial problem specifications and long documents.

Uptime and availability

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

94.61%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.

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

Data handling per route

Each route hosting O1 has its own privacy posture, residency, and GDPR terms. Postures are maintained by Opper with a last-verification timestamp.
