Does O1 support zero data retention?

Not self-serve on Pay-as-you-go. Zero data retention for O1 is available on request via Opper Enterprise — contact hello@opper.ai.

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

O1 (December 2024) is a dated snapshot of OpenAI's reasoning model, pinned to a specific build so that behavior stays stable across requests. Like the rolling O1, it reasons deeply before answering, trading inference time for accuracy on hard problems. The snapshot accepts text and image input, supports function calling, structured outputs, and streaming, and carries a 200,000 token context window. It is well suited to science, mathematics, and software engineering tasks that reward multi-step reasoning. OpenAI has since released newer reasoning models with extended capabilities, so this snapshot is now an older option retained mainly for reproducibility and compatibility.
