In addition, the company has expanded the tool restrictions for all users by deploying an easy version based on its O4-Mini model. It states that the function of deep research O4-Mini gives slightly shorter answers, but “almost as smart, more economical and provides similarly qualitative results” as the original version. Openai previously released Tool for use by paying Pro, Plus, team subscribers, Edu and Enterprise. But even they have a limited number of deep studies per month.

In addition, users, for example, had access only to 10 requests, while the Pro subscribers paying $ 200 a month had a limitation of 125. Now that users have reached their limit on the original version, ChatGPT will switch to an easy one. Plus and team subscribers are currently receiving additional 15 deep research per month in addition to their 10, while professional users receive additional 125 tasks based on the easy version of the tool in addition to their 125. Enterprise and Edu users gain access to light tools next week and receive another 15 requests a month. As for free users, they can use an O4-Mini tool to get up to five answers per month.
Deep studies are able to analyze websites and various sources for creating thorough reports with quotes. The company claims that the tool is “precisely tuned to the Openai O3 reasoning model, but the light version“ is much cheaper for service ”.
