1. Log into ChatGPT and confirm you are on the updated Deep Research
mode, not the legacy version. If you are still on the old interface,
you will lose access after March 26 and your research workflows will
break.
2. Run one real market research query in the updated Deep Research
before you do anything else today. The tool does multi-step research
across multiple sources and delivers a cited report. The best first
test is a competitor analysis or a customer pain point scan in your
industry.
3. The updated Deep Research produces structured, citable reports. Do
not close the tab when it is done. Copy the output into a working
document and tag it with the date and the query you ran. Build a habit
of saving these outputs.
4. If you have never used Deep Research for competitor analysis, today
is the day. The tool can replace hours of manual scanning across
competitor websites, social media, and public reviews. The prompt
structure that works best leads with your business context before the
research question.
5. The legacy Deep Research mode is going away because the new version
is better. Faster synthesis, better source attribution, more reliable
outputs. If you have been avoiding the switch because the old version
was working fine, this is not a downgrade. It is the version you
should have been using already.
