Message generation interrupted, stuck at Generating #2137
Description
I am experiencing stuck / interrupted behavior when using opencode. I have tried different models (gemini, ollama) but the behavior is the same.
I am constructing a request and the response is either stuck at Generating or it gets interrupted in the middle of streaming the response.
See the following screenshot of a test conversation:
I have deleted the following directories, but to no avail:
- ~/.cache/opencode
- ~/.bun/install/cache
OS: arch linux
opencode version: v0.5.12

Also started to have similar issues recently with gemini, especailly with
gemini-2.5-pro.OS: NixOS
opencode version: v0.5.12
Also did cleanups, but no luck, gemini just get stuck by doing enything.

For me this happens with Anthropic models, and only in a situation that I have two opencode running at the same time. The second one I run keeps doing its work and causes the first one to get stuck. The esc key doesn't help either, I have to ctrl+c twice and get back to the same session and continue.

Hmm interesting I will try to reproduce
zatevakhin commentedon Aug 21, 2025
FYI: I was running only one instance of
opencodefor repro and result is thatgemini-2.5-proget stuck ongenerating....balpert89 commentedon Aug 21, 2025
same as @zatevakhin I am only running 1 instance of opencode.
rekram1-node commentedon Aug 21, 2025
For those having problems can you run:
and show me output? Just run w/ whatever model is giving you trouble
balpert89 commentedon Aug 21, 2025
sure:
afterwards, when looking at the session I can see the described issue:

I faced a similar behavior with my self-hosted model (Qwen3-coder) running with vLLM. The resulting prompt coming from OpenCode sets the
tool_choicefield toauto, which does not play nicely with the default configuration of vLLM. It resulted into some 400 errors, but somehow OpenCode's TUI was not showing up error details and was just hanging with this Generating message. It turns out I had to use the --enable-auto-tool-choice flag of vLLM to avoid the 400s and make it work.alex-hjkl commentedon Aug 22, 2025
Has the same problem with google/gemini-2.5-pro more than a week.
But it works for not google providers
rekram1-node commentedon Aug 22, 2025
what happens if you try deleting ~/.cache/opencode
^^ it is a dir
alex-hjkl commentedon Aug 22, 2025
Doesn't help. It goes back from "working..." to "enter" state pretty quick and stops "Generating"

Yes, have hanging only in UI mode. I using 2 MCP servers - both locally - context7, gitlab mcp.
rekram1-node commentedon Aug 31, 2025
ahh can you try disabling the gitlab mcp and trying again, wonder if that is the issue
43034r commentedon Aug 31, 2025
Tried without any MCP - works.
restarted two local containers context7, gitlab mcp, - hello works, but another promt return "Generating..."
gitlab mcp - look likes this one is the root cause in my case. TY for help.
alex-hjkl commentedon Sep 1, 2025
Super, v0.5.29 works for me. No mcp. Thanks a lot!
sQVe commentedon Sep 1, 2025
I'm seeing this issue fairly often, and I'm using these MCPs:
rekram1-node commentedon Sep 1, 2025
thx for sharing @sQVe it definitely isnt context7 but it might be one of the others
imajus commentedon Sep 9, 2025
Also have the same issue, and the worst is that killing OpenCode and restarting with
opencode --continueget me to the same hanged state. Starting normally and switching to previous session via/sessionshas the same effect.The only way to fix this AFAIK is to start a completely new session, which is annoying because I need to resemble a full conversation history manually. Unless I would face the same issue at some point, which is very likely.
I'm running Arch Linux and last time I faces it I was using Claude Opus 4.1 in PLAN mode.
rekram1-node commentedon Sep 9, 2025
Can you show me what you see if you do:
opencode run "hello" -c --print-logs
in the session that hangs
rekram1-node commentedon Sep 9, 2025
does it only happen on file edits maybe?
sagarbehere commentedon Sep 19, 2025
I just encountered this after downloading and using opencode with gemini-2.5-pro. It happened within a few minutes. I am not using any MCPs.
rekram1-node commentedon Sep 19, 2025
@sagarbehere did it happen when it tried editing a file? if so what file type
could you share error log
sagarbehere commentedon Sep 19, 2025
@rekram1-node It happened while I was in a back-and-forth chat with gemini-2.5-pro and during this chat I'd occasionally ask it to update a specification document (a .md file). However, the particular chat messages in response to which it got stuck on Generating.. were not requests to edit the .md file.
rekram1-node commentedon Sep 20, 2025
hmm if you run into it again can you share the latest log file when it happens?
