In ChatGPT this week, OpenAI released a new Deep Research tool in ChatRPT that was updated by the company’s own . The San Francisco-based artificial intelligence (AI) giant introduced the agentic research assistant in February 2025, which was designed to help users conduct multi-step research on complex topics. a year later, the firm is adding additional control to the tool and added ‘a new full-screen report viewer’ that allows users more flexibility in both making the research document and viewing it.

Deep Research in ChatGPT Gets New Features

During its release notes for ChatGPT, the AI giant announced and described the new capabilities in Deep Research. The improvements can be grouped into two groups the first on the new controls, and the second on viewing experience. OpenAI has now added an option to let users narrow the focus of research on specific websites in the first group, allowing for use with open AI.

So far, the only way Deep Research could be grounded was by specifying the limiters on the website in the prompt itself. Nevertheless, the ability to add this information into the tool at a system level (such as adding it) will allow users to see more accurate and focused responses. In addition to enabling linked apps during research, users can also enable connected apps and use them as trusted sources of information.

In addition to this, users can edit a research plan before it begins. This helps particularly since earlier users could only redirect the research after it started to do so. Suppose a user wanted to change details before the plan was created, they would have to start all over again. A mid-run shift in the direction of the research is still a possibility for s to be able to change its course.

In the second wave of improvements, Deep Research now has a new sidebar entry point and full-screen report viewer with redesigned design as well as. The latter opens in a document viewer-like interface, with side panels for index (left) and citations (right) on the side panel. The index is also interactive, and users can click on any heading or subheading to get quickly to that part.

However, the AI firm has also updated GPT-5 as well in a separate way. ChatGPT and application programming interface (API) 2 Instant model in ChatGT. OpenAI says the responses are now “more measured and grounded” in tone, meaning they fit contextually with the conversation. Further, in addition to the more detailed output and broader responses of how-to questions (and advice) that are given by the new model, it also provides clearer output with better answers.
