I’ve been trying since Friday, still no luck. It gets stuck at ~20% and if I leave the chat and return it shows a button “Starting… 0“ and stays there forever.
Same, tried everything with no success as well. I guess they are reallocating the deep research for the war resources and not for our normal customers
Same issue here and trying to restart it multiple time ran out of the full-model deep research queries 
Escalated this to OpenAI.
same since end of Feb. no updates so far
Facing the same issue 
Seems need to check out Gemini, Claude, or Grok.
Me too! I’ve been experiencing the same error for the last 4 days.
maybe is region especific
I sent them the requested screen recording the system recording. So far still no solution, Claude “Research” is working very good, I never tried it before.
I have the same issue, I’ from Brazil, so maybe region specific.
And I have PRO subscription
I am having the same issue with Plus - also from Brazil. I have reported it already with no response as of yet. Has anyone heard back from OpenAI?
no responses here as well.. medo de ter perdido mil reais.
The biggest problem is losing all the investigations (advanced deep research mode) because we kept testing to see if the issue was on our end. They should restore the number of searches and even give a bonus. extremely frustrating.
Same here… What’s happening with OpenAI?
I’m having the same issue as the OP, plus failed deep research consumed my tokens (??). Pls get your s*** together and provide a solution.
Hey, from Brazil here, I’m having the same issue too, for 3 days straight. I’ve lost all of my Deep Research usage credits, tried to debug with the Support AI, but nothing worked.
guys have a try, mine works!
Seems like they fixed it, but my queries are still spent. Least they could do is reset them for the afflicted users.
OpenAI has escalated the issue internally today, and it should be fixed, but reach out here if not.
