OpenAI has launched O3 PRO for ChatGPT, marking a significant advancement in both performance and cost-efficiency for its reasoning models. This new model, O3-Pro, is now accessible through the OpenAI API and the Pro plan, priced at $200 per month. The company highlights substantial improvements with O3 PRO and has also dropped the price of its previous o3 model by 80%. This strategic move aims to provide users with more powerful and affordable AI capabilities, challenging competitors in the AI model market and expanding the boundaries of reasoning.
The O3-Pro model is set to offer enhanced raw reasoning capabilities, but early reviews suggest mixed results when compared to competing models like Claude 4 Opus and Gemini 2.5 Pro. While some tests indicate that Claude 4 Opus currently excels in prompt following, output quality, and understanding user intentions, Gemini 2.5 Pro is considered the most economical option with a superior price-to-performance ratio. Initial assessments suggest that O3-Pro might not be worth the higher cost unless the user's primary interest lies in research applications. The launch of O3-Pro coincides with other strategic moves by OpenAI, including consolidating its public sector AI products under the "OpenAI for Government" banner, including ChatGPT Gov. OpenAI has also secured a $200 million contract with the U.S. Department of Defense to explore AI applications in administration and security. Despite these advancements, OpenAI is also navigating challenges, such as the planned deprecation of GPT-4.5 Preview in the API, which has caused frustration among developers who relied on the model for their applications and workflows.

OpenAI has recently launched its newest reasoning model, o3-pro, making it available to ChatGPT Pro and Team subscribers, as well as through OpenAI’s API. Enterprise and Edu subscribers will gain access the following week. The company touts o3-pro as a significant upgrade, emphasizing its enhanced capabilities in mathematics, science, and coding, and its improved ability to utilize external tools.
OpenAI has also slashed the price of o3 by 80% and o3-pro by 87%, positioning the model as a more accessible option for developers seeking advanced reasoning capabilities. This price adjustment comes at a time when AI providers are competing more aggressively on both performance and affordability. Experts note that evaluations consistently prefer o3-pro over the standard o3 model across all categories, especially in science, programming, and business tasks. O3-pro utilizes the same underlying architecture as o3, but it’s tuned to be more reliable, especially on complex tasks, with better long-range reasoning. The model supports tools like web browsing, code execution, vision analysis, and memory. While the increased complexity can lead to slower response times, OpenAI suggests that the tradeoff is worthwhile for the most challenging questions "where reliability matters more than speed, and waiting a few minutes is worth the tradeoff.”

OpenAI has launched o3-pro, a new and improved version of its AI model designed to provide more reliable and thoughtful responses, especially for complex tasks. Replacing the o1-pro model, o3-pro is accessible to Pro and Team users within ChatGPT and through the API, marking OpenAI's ongoing effort to refine its AI technology. The focus of this upgrade is to enhance the model’s reasoning capabilities and maintain consistency in generating responses, directly addressing shortcomings found in previous models.
The o3-pro model is designed to handle tasks requiring deep analytical thinking and advanced reasoning. While built upon the same transformer architecture and deep learning techniques as other OpenAI chatbots, o3-pro distinguishes itself with an improved ability to understand context. Some users have noted that o3-pro feels like o3, but is only modestly better in exchange for being slower. Comparisons with other leading models such as Claude 4 Opus and Gemini 2.5 Pro reveal interesting insights. While Claude 4 Opus has been praised for prompt following and understanding user intentions, Gemini 2.5 Pro stands out for its price-to-performance ratio. Early user experiences suggest o3-pro might not always be worth the expense due to its speed, except for research purposes. Some users have suggested that o3-pro hallucinates modestly less, though this is still being debated.
