Does GPT-4.1 Nano support zero data retention?

Not self-serve on Pay-as-you-go. Zero data retention for GPT-4.1 Nano is available on request via Opper Enterprise — contact hello@opper.ai.

Where is GPT-4.1 Nano hosted?

GPT-4.1 Nano runs on US hosting routes through the Opper gateway.

Is GPT-4.1 Nano trained on prompts and outputs?

No. Every hosting route for GPT-4.1 Nano is configured so customer prompts and outputs are not used to train models by default.

Is a GDPR DPA available for GPT-4.1 Nano?

Yes. A GDPR Data Processing Agreement is available on at least one route serving GPT-4.1 Nano. Contact hello@opper.ai to receive it.

GPT-4.1 Nano

by OpenAI

GPT-4.1 Nano is the smallest and fastest model in the GPT-4.1 family, built for high-throughput and cost-constrained workloads. Despite its compact size, OpenAI keeps the 1 million token context window so it can still process extensive documents and datasets. It supports vision input, JSON schema structured output, and function calling, which makes it viable for classification, simple transformations, extraction, and lightweight reasoning at scale. It is the right choice when throughput and per-call cost are the main constraints but reliable structured output is still required.
