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 o1-pro good for?

Hard, low-volume problems where paying for more compute per query is fine: OpenAI says the compute-heavy variant of o1 answers more accurately.

When is o1-pro not a good fit?

Almost all routine work: it sits at the very top of OpenAI's price range. No web search, code execution or file input, its knowledge is years old, and OpenAI plans to shut it down in October 2026.

What is the cheapest way to run o1-pro?

The cheapest hosted rate is $150.00 / $600.00 per 1M tokens via OpenAI.

How does o1-pro compare with o3-pro?

OpenAI says o3-pro is to o3 what o1-pro was to o1: it spends more compute to think longer and give more reliable answers, can search the web, run Python and analyze files as it reasons, and beat o1-pro in OpenAI's own evaluations. Same 200K-token context and text and image input. o1-pro lists at 650% more per 1M input tokens and 650% more per 1M output tokens than o3-pro. It came out 3 months earlier and has an older knowledge cutoff (October 2023 against June 2024).

Can I self-host o1-pro?

No. OpenAI does not publish the weights; o1-pro is available only through hosted APIs.
