How we price

Order

Providers are listed cheapest input rate first, then by output rate, a tie going to the creator's own listing. A provider that lists the model without a published rate sits at the end.

Prices

Base-tier, on-demand rates in USD per 1M tokens, converted at ECB reference rates where a provider publishes in another currency. Cached-input and batch rates show only where a provider publishes them. "Cheapest" marks the one provider with the lowest input and output pair; a tie wears no badge.

Cost

Input rate times the input tokens plus output rate times the output tokens, at the monthly volume set above the table. Cached-input, batch, long-context and reasoning-token billing are not modelled.

Heads up: Base-tier, on-demand rates per 1M tokens; cached, batch and long-context tiers excluded. A provider may serve a shorter context or a quantized build than the creator's release. Verify before provisioning. More on how we price.

Common questions

What is o3-deep-research good for?

Autonomous, multi-step research reports that search and synthesize many online sources, with MCP connectors for private data. It was OpenAI's deep research model.

When is o3-deep-research not a good fit?

Anything new: OpenAI retired it in July 2026. It had no function calling or structured output, took no audio or video input, and its knowledge is dated.

What is the cheapest way to run o3-deep-research?

The cheapest hosted rate is $10.00 / $40.00 per 1M tokens via Azure.

Can I self-host o3-deep-research?

No. OpenAI does not publish the weights; o3-deep-research is available only through hosted APIs.
