OpenAI has officially announced a major update to its deep research tools for ChatGPT, aiming to provide users with a more professional and efficient experience in reading and generating reports. The most significant change in this upgrade is the introduction of a core engine powered by the GPT-5.2 model, along with a new full-screen viewer feature.
The new full-screen viewer changes the previous fragmented way of presenting information. Users can now fully browse AI-generated in-depth reports in a separate window, and they can precisely jump to specific content areas through the newly added interactive table of contents on the left side. On the right side of the report, all cited references are clearly listed. This design greatly improves the efficiency of processing complex information, making in-depth research truly readable and professional.
In terms of functional details, OpenAI has further empowered users. Now, users can specify that ChatGPT only fetches materials from specific websites or associated applications, making research results more focused. At the same time, the research progress has also become transparent, allowing users to intervene in real-time during the report generation process, flexibly adjust the research scope or supplement reference sources. After the report is completed, the system supports downloading in mainstream formats such as Markdown, Word, and PDF, making it convenient for users to handle afterward.
It is reported that this enhanced version of the deep research tool is now available to Plus and Pro users first. New ChatGPT Go subscribers and free users don't have to wait long, as the relevant updates will be implemented gradually in the coming days.
Key Points:
🖥️ Full-Screen Interaction Upgrade: A new full-screen viewer has been added, supporting table of contents navigation and reference source comparison, significantly optimizing the reading experience of long in-depth reports.
⚙️ Model Engine Replacement: The deep research tool is now fully integrated with the GPT-5.2 model, offering more accurate logical reasoning and comprehensive web information retrieval capabilities.
🔍 Deep Customization Permissions: Supports specifying data source fetching and allows users to monitor the progress in real-time and dynamically correct the research scope during report generation.
