OpenAI to release o3 Pro for ChatGPT Pro users this week

OpenAI is set to release the o3 Pro model for ChatGPT Pro users today, June 4, 2025. This aligns with earlier indications from company insiders and codebase discoveries, suggesting a focus on new features tailored for business applications.

The o3 Pro model builds upon the capabilities of the previously released o3 and o4-mini models. These models introduced advanced reasoning abilities, enabling ChatGPT to autonomously utilize tools such as web browsing, code execution, and image analysis to solve complex problems. The o3 Pro model is expected to further enhance these capabilities, offering improved performance for professional users.

In addition to the o3 Pro model, OpenAI is anticipated to expand its ChatGPT Connectors feature. This functionality allows users to integrate ChatGPT with third-party applications like Google Drive and Slack, enabling the AI to access and process information from these platforms. The upcoming update is expected to introduce support for additional services, including Dropbox and Box, and will allow for custom integrations via the Model Context Protocol (MCP). MCP enables users to define custom endpoints, facilitating seamless integration with proprietary systems and specialized data sources.

These developments underscore OpenAI’s commitment to serving the enterprise market by providing tools that facilitate deeper integration of AI into business workflows. By improving the capabilities of ChatGPT and enabling seamless access to external data sources, OpenAI aims to position its platform as an indispensable asset for organizations seeking to leverage AI for complex tasks and decision-making processes.
