Built for
  • Text and code. Drafting, summarising, extraction, chat and code, with the output streamed back as it is generated.
  • Vision. Send screenshots, photos, charts and documents alongside your prompt.

Edge gateways

Requests enter at the gateway nearest your app and go straight to the model, so routing adds very little to each call.

One key, every model

Switch models by changing a string. One prepaid balance covers all of them, billed per token.

Nothing stored

We keep token counts for billing, never your prompts or responses.

Questions.

How much does GPT 4.1 Nano cost?

$0.292 / 1M tokens output and $0.073 / 1M tokens input, 27% below OpenAI's list price. You pay per token from a prepaid balance, with no subscription or minimum. We match your first $5 top-up, so you start with $10 of credit.

Is it the real GPT 4.1 Nano?

Yes. Your requests run on OpenAI's GPT 4.1 Nano, not a distilled copy or a substitute. The discount comes from how we buy capacity, not from changing the model.

Which tools can use GPT 4.1 Nano?

Anything that speaks the OpenAI API: set the base URL to our endpoint and use the model ID gpt-4.1-nano. We have setup guides for Cursor, Codex, OpenCode, the OpenAI and Vercel AI SDKs, LangChain and more.

How fast is it?

Requests go through our edge gateways, so the network hop adds very little on top of GPT 4.1 Nano's own generation time. Responses stream back token by token.
