OpenAI’s o1-pro AI model is now available for developers via its API (application programming interface).
The OpenAI Developers announced the launch of the o1-pro in API via a post on X (formerly known as Twitter). The o1-pro model uses more computing power than the o1 model to provide more accurate and consistent responses.

It supports vision, function calling, and structured outputs. It also works with Responses and Batch APIs. This provides developers with better responses than the previous models by using more computing.
The o1-pro model boasts a 200,000-token context window, a knowledge cutoff of October 2023, and supports reasoning tokens. It is priced at $150 (Rs 12,900) per million input tokens and $600 (roughly Rs 51,800) per million output tokens. It is expensive because of higher computing costs.
OpenAI believes that the model’s improved performance will attract developers working on complex tasks. Currently, it is available only to select developers on the paid 1-5 tiers.
The o1-mini and o3-mini models cost $1.10 (around Rs 94) per million input tokens and $4.40 (roughly Rs 380) per million output tokens.
