OpenAI rolls out a ‘lightweight’ version of its ChatGPT deep research tool

OpenAI has launched a lighter version of its ChatGPT tool, called "deep research," designed to streamline in-depth research by web surfers. This simplified model, powered by OpenAI's o4-mini, sacrifices some complexity to reduce costs and response times, making it more accessible without compromising quality too much. Free users can now access this streamlined version immediately, while enterprise and educational users will get the same treatment next week as part of their Team plan limits.
