OpenAI Releases o3-Pro Reasoning-Focused AI Model: What’s New

OpenAI’s most recent model, known as o3-Pro, has been made available. Building on the characteristics of its predecessor, o1 Pro, the new model aims to increase accuracy, depth, and dependability when completing tasks pertaining to programming, science, mathematics, and education. Up to June 10, 2025, the new model is only available to ChatGPT Pro subscribers who have API access.

With additional capabilities like online browsing, file analysis, Python execution, and image interpretation, o3 Pro is an improved version of OpenAI’s flagship o3 model.

The model selector option for Pro subscribers will switch from the o1-pro model to the o3-pro AI model. The flagship-tier reasoning model from the o3 family is noteworthy since it comes about two months after the San Francisco-based AI company unveiled the o4-mini and baseline o3 models.

Web search, file analysis, computer vision with reasoning, Python, memory access to customize responses, and other technologies are all accessible to the o3-pro AI model. It should be noted, nonetheless, that the model takes a little longer to provide results than o1-pro because of tool accessibility.

Limitations and Availability

O1-pro has been replaced by o3-pro, which is now accessible to all ChatGPT Pro and Team users via the toggler, as previously mentioned. Enterprise and educational users should have access in around a week. For the time being, o3-pro does not allow temporary conversations, picture production, or Canvas features because of ongoing technical work.

According to report, o3-pro is perfect for sophisticated applications in business, research, and creative writing since it maintains the same foundation as the o3 model but gains from better fine-tuning.
