Deep Research API (deep-research-pro-preview-12-2025) — jobs stay in_progress indefinitely with complex prompts

Hi there thanks for sharing feedback.

  1. There’s no known issue with silently hanging on complex prompts. I was unable to reproduce your issue. Could you share an example prompt you used that caused this? I used this prompt for testing and got a response ~4 minutes [1]
  2. Max research time is capped at 60 minutes, though most complex tasks should take 20 minutes. Have you tried setting out a longer timeout for these complex tasks?
  3. To receive intermediate reasoning steps (thoughts) and progress updates, you must enable thinking summaries in the agent_config. If this is not set to "auto", the stream may only provide the final results without the real-time thought process.
  4. There is no known issue. If it still “stuck”, it may be due to the agent still running. If it timeouts due to 60 min max limit, it should fail. Let me know if that’s NOT the case.
