ALBAWABA – OpenAI, the American artificial intelligence (AI) research organization, has launched its most expensive AI model, o1-Pro.
OpenAI’s new o1-Pro
OpenAI launched its most expensive reasoning artificial intelligence (AI) model, O1-Pro, on its API platform—the most powerful platform for building AI products. According to the company, the new model delivers more advanced and consistent responses.
The O1-Pro is now available to developers at about $150 per million tokens (~750,000 words) and around $600 per million tokens generated by the model. This new model is considered somewhat pricey compared to GPT-4.5 and the regular O1.
OpenAI says the new features and AI technologies offered in the model will justify the high fees.

“O1-pro in the API is a version of o1 that uses more computing to think harder and provide even better answers to the hardest problems. After getting many requests from our developer community, we’re excited to bring it to the API to offer even more reliable responses,” OpenAI stated.
The company says the new Pro model performs excellently with coding and math problem-solving. However, a demo was available to ChatGPT’s Pro subscribers since December 2024, and users reported several issues related to problem-solving.
OpenAI claims the new model is now fully developed and ready to perform at its best.
