Does GPT-5 support zero data retention?

Not self-serve on Pay-as-you-go. Zero data retention for GPT-5 is available on request via Opper Enterprise — contact hello@opper.ai.

Where is GPT-5 hosted?

GPT-5 runs on both EU and US hosting routes through the Opper gateway. Pick the route that matches your residency requirement.

Is GPT-5 trained on prompts and outputs?

No. Every hosting route for GPT-5 is configured so customer prompts and outputs are not used to train models by default.

Is a GDPR DPA available for GPT-5?

Yes. A GDPR Data Processing Agreement is available on at least one route serving GPT-5. Contact hello@opper.ai to receive it.

GPT-5

by OpenAI

GPT-5 is OpenAI's GPT-5 generation reasoning model, built for complex problem-solving, coding, and professional applications. It accepts text and image input and offers a 272,000-token context window, which supports working over large codebases, extensive documentation, and long-form analysis in a single request. The model uses internal reasoning to plan, evaluate alternatives, and refine answers across multi-step tasks. With tool use, structured outputs, and vision, GPT-5 suits agentic workflows, code analysis, and knowledge-intensive applications.

Get started

Call GPT-5 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 your coding agent — Claude Code, Cursor, Codex, and more — and it'll wire up Opper for you.
