OpenAI launches o1-pro API model with advanced capabilities

OpenAI has officially launched o1-pro, the most advanced version of its o1 “reasoning” AI model, in its developer API at a significantly higher price point.

The company claims that o1-pro utilizes more computational power than the original o1, resulting in “consistently better responses.”

With its enhanced reasoning capabilities, OpenAI expects developers to be willing to pay the premium for improved accuracy and problem-solving efficiency.

However, early feedback from ChatGPT Pro users—who have had access to o1-pro since December—has been mixed. Some users have reported issues with certain tasks, such as solving Sudoku puzzles.

The pricing for o1-pro in the API is notably high, at $150 per million input tokens (~750,000 words) and $600 per million output tokens generated by the model.

This places it well above the costs of OpenAI’s GPT-4.5 and the standard o1 model.

Currently, the o1-pro API is available only to a select group of developers. An OpenAI spokesperson told TechCrunch:

“o1-pro in the API is a version of o1 that uses more computing to think harder and provide even better answers to the most complex problems. After receiving numerous requests from our developer community, we’re excited to bring it to the API to deliver even more reliable responses.”
