These adoption and deployment observations remain context only. They do not change this model's ModelCap Index score or rank.
The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.

o1-pro: common questions
How much does o1-pro cost per 1M tokens?
o1-pro is listed at $150 per 1M input tokens and $600 per 1M output tokens as of 22 September 2026. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $600 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
What is the context window of o1-pro?
o1-pro has a published context window of 200K tokens (200,000) and a maximum output of 100K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.
Is o1-pro open-weight?
API only. No downloadable model weights are linked in the current source data; access is through a hosted API or product.
Which API providers serve o1-pro?
One provider serves o1-pro through OpenRouter as of 22 September 2026: OpenAI. Each provider's price, context limit, quantization and measured uptime are in the providers table above.
When was o1-pro released?
o1-pro first appeared in the catalogue on 19 Mar 2025, with a published knowledge cutoff of 2023-10-31. It has since been superseded by o3 Pro. Rank and price movements since then are recorded on the site's changes feed.
