About OpenAI o3-pro
It is revealed that, like o1-pro, o3-pro continues to excel in domains such as math, science, and coding. Like o3, o3-pro has access to tools that make ChatGPT useful- it can search the web, analyze files, reason about visual inputs, use Python, personalize responses using memory, and more. And since this model has access to these tools, responses typically take longer than O1-pro to complete. Therefore, it is recommended to use o3-pro for challenging questions where reliability matters most.
It is revealed that in expert evaluations, reviewers consistently prefer o3-pro over o3, especially in key domains like science, education, programming, business, and writing help. It is rated higher for clarity, comprehensiveness, instruction-following, and accuracy.
To assess the key strength of o3-pro, a 4/4 reliability evaluation was used, where a model is considered successful only if it correctly answers a question in all four attempts.
Limitations
Due to a technical issue, temporary chats are currently disabled. Image generation and Canvas are not supported within o3-pro.
OpenAI o3-pro: Availability
It is available in the model picker for ChatGPT Pro and Team users, replacing o1-pro. Enterprise and Edu users will get access the week after. It is also available in OpenAI’s developer API.
