   Thanks for the report! I think this is a duplicate of #56858, which you opened a few minutes earlier with the same description and screenshot. Let's keep the discussion there. It already has a few questions (version, provider/model, OS/terminal, and what the session shows while it's stuck) that will help us look into it.

   Possible duplicates and related issues, ordered by likelihood:

   • "OpenAI Chat stream ended without finish_reason" #56858: your earlier, identical report of this problem
   • server: model step hangs with no timeout, session stays busy until interrupted #53747: a model step stalls with no timeout and the session stays busy until it's interrupted by hand
   • session: auto-continue after a stream interruption is delivered as an unmarked synthetic user message #56295: the automatic "continue" that OpenCode sends after a stream ends without finish_reason
   • run: openai-compatible provider (Z.AI) stream always ends without finish_reason; interactive sessions unaffected #55124 / opencode-go: GLM-5.3-Flash long streams cut off without finish_reason, repeated retries #50146: other reports of streams ending without finish_reason

   The bot will close this issue as a duplicate in 1 day unless you reply explaining how it's different.

   Closing this as a duplicate of #56858, your identical report from a few minutes earlier. We waited a day in case this one covered a different problem, and there's been no reply. Please follow up on #56858 and add the details asked for there: OpenCode version, provider/model, OS/terminal, and what the session shows when it gets stuck. #53747 (a step stalls with no timeout until it's interrupted) is also closely related. If this was actually a different problem, reply here and we can reopen it. Thanks!
