Run a Deep Research request that requires researching multiple websites and sources. Wait for the research to complete. Check the final report for citations and the research progress/source activity UI. I reproduced this 3 times in a row with separate Deep Research runs.
Deep Research should continue until the requested scope is adequately researched, include working citations for sourced claims, and show the research activity/source trail, including the number and list of websites or pages visited.
Deep Research finishes much earlier than expected, returns results with no citations, and no longer shows the number or list of websites/pages visited. As a comparison, I also used a normal ChatGPT conversation and simply asked it to “do deep research” without invoking Deep Research, and that ordinary chat session produced a noticeably more thorough result than the dedicated Deep Research feature.
