OpenAI has officially launched the most powerful version of its o1 “reasoning” AI model, the o1-pro, in its developer API, at a notably higher price point.
According to the company, o1-pro leverages more computational power than the original o1, resulting in “consistently better responses.”
With this enhanced performance, OpenAI hopes that developers will be willing to pay the premium, as the model integrates cutting-edge technology for improved results. However, early reviews of o1-pro, available to ChatGPT Pro subscribers since December, have been mixed. Some users reported issues with features like Sudoku puzzles, among others.
The pricing for OpenAI’s o1-pro API model stands at $150 per million tokens (~750,000 words) for input data and $600 per million tokens generated by the model. This is significantly higher than the cost for OpenAI’s GPT-4.5 and regular o1 models.
Currently, the o1-pro API is only available 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."
