Opencode stuck in "generating"

[goszczynskip]

When submitting a prompt, opencode doesn't return any response and is unresponsive to double-esc key press (interrupt). It shows "generating". Stopping process with double Ctrl-C exits tui but doesn't return to terminal. Hitting Ctrl-C the third time exits back to the terminal.

I've tried to change the model or prompt. Still, it produces the same

- kitty 0.37.0
- opencode 0.6.8
- model (tested on Anthropic Sonnet 4 and GPT OSS 120B (groq)).

This issue might be a duplicate of existing issues. Please check:

• #2137: Very similar behavior - getting stuck at 'Generating' state with interruption issues across different models
• #1418: Getting stuck on 'working' state with double ESC not exiting, also in terminal environment
• #2494: Interrupt functionality (ESC twice) not working as expected
• #1179: ESC interruption often doesn't work, leading to unusable sessions
• #888: ESC interrupt oscillating between states without actually interrupting (closed but may be related)

Feel free to ignore if none of these address your specific case.

Running without tui is also hanging

[stuck here]

[goszczynskip]

I've tried to delete ~/.cache/opencode, but it didn't resolve the issue. It's still stuck on session.update publishing

[BrianLeishman]

Claude Code also gets stuck like this sometimes, sending just a . can kick it and make it carry on

[rekram1-node]

Does this hang happen regardless of directory?

[goszczynskip]

Yes, I've just tested it in a different directory — same behavior.

[colout]

not sure if it helps, but I ran into this with groq through my litellm proxy. Because it's through litellm, i saw this error in the logs section of the litellm ui:

litellm.RateLimitError: RateLimitError: GroqException - {"error":{"message":"Request too large for model `moonshotai/kimi-k2-instruct-0905` in organization `xxxxxxxxxxxx` service tier `on_demand` on tokens per minute (TPM): Limit 10000, Requested 12874, please reduce your message size and try again. Need more tokens? Upgrade to Dev Tier today at https://console.groq.com/settings/billing","type":"tokens","code":"rate_limit_exceeded"}}

...it turns out my credit card expired so they downgraded me to free tier (with the silly low limit). Since you're also on Groq, check your limits...that might be it

[ViniciusRed]

I'm having the same problem. I installed opencode today after an AI_APICallError: The messages parameter is illegal. Please check the documentation. I told it to continue, it read the file and responded but stopped after that it didn't work anymore even though I told it to continue, after I told it to continue several times it gave an error of

after that it worked again

Provider: z.ai Model: GLM-4.5-Flash

after update 0.6.9 it worked again for a while and stuck again

[goszczynskip]

I was playing around and resolved this by downgrading versions sequentially to 0.6.5. After running again, I got it working. Now it started working after upgrading back to 0.6.10. I'm not sure if downgrades fixed anything, or if the application was in a bad state and some LLM response got it unstuck.

Although the issue of ignored interrupt signals (esc+esc) during the session.updated publishing event is still present in the code, so I'm leaving this issue open.

[NaikSoftware]

Sometimes the same problem

[maciejk-code]

Yeah happens for me too. Unfortunately too often

[mauriciojuniorsympla]

after 3 or 4 prompts, it just get stuck

[rekram1-node]

This seems related to mcp servers, @goszczynskip can you disable the figma mcp and try again?

The remote mcps seem to be hanging

same goes for others in this thread, try disabling your remote mcp

[NaikSoftware]

Stuck again on the latest 0.9.0. After completing a plan in planning mode. All results are successfully rendered, but I see the message "Generating..."

[bcardarella]

I am also getting stuck here sometimes. Even hitting esc to cancel does nothing. I have to ctrl-c out. If I restart opencode with --continue it is stuck back in that loop again. If I start a new instance of opencode it seems OK.

I've let it sit for 3 hours and it was still stuck at this step.

I don't know where the context is stored for --continue but it may make sense to see if that can be accessed and perhaps something in that context is putting opencode into the funky state?

[rekram1-node]

@bcardarella if you do the --continue flag you would need to reprompt llm with at least a "continue" or a "." are you trying that

opencode --continue just opens up last session (just wanna make that clear)

[bcardarella]

@rekram1-node next time this happens I'll do a screen recording so show the behavior, but what I was seeing was Opencode was unresponsive. It was stuck at the Generating... and when I reprompted it just stalled as well. I didn't try . in the prompt though so if I run into this again I'll give that a shot to see what happens.

[rekram1-node]

@bcardarella yeah there is a UI bug but if you exit opencode and reopen it is no longer in a Generating state, you would need to reprompt it in that case

[imekinox]

This happens when you hit rate limits on calude. opencode does not show the rate limit error and gets stuck in generating instead. If you open claude-code you'll see the error.

[bcardarella]

@imekinox I'm on Max plan signed in with the Claude Code login with Opencode. Furthermore, this has happened when using for the first time in over a 24 hour period.

[imekinox]

I'm in the max plan too and just happened to me when I posted here. It might be something else in your case but definitely the client is not handling rate limits properly.

[bcardarella]

Perhaps? Is there a debug mode for Opencode mode so we could see behind the curtain or is Claude's api just a black box for this stiff?

[rekram1-node]

if you run with opencode run "<prompt>" --print-logs you can see the logs

You could also just read latest log file, regardless we need to figure out what their api returns in this case and surface it in a clearer way....

[bcardarella]

Thank you, if I run into it again I'll try to capture the logs for you all.

[seaweeduk]

I've been getting this consistently on the anthropic plans when i hit my usage limits, not sure when it started occuring but it always just stays stuck on generating now. Opencode used to show the error in the top right toast about api limits.

My workaround at the moment is just opening claude code to check if its my usage limit when its stuck on generating, and what time it resets (would also be nice to see the reset time in opencode).

[seaweeduk]

[rekram1-node]

ill try replicating, thx for the details

[raymelon]

Same issue. Using Grok Code Fast 1. The only way to bring it back to its senses is by turning the internet off, forcing an error.

After that, switch to Code Supernova 1M to finally make Build mode edit some code once again.

If you are not comfortable with that model, do a revert, switch back to Grok Code Fast 1, and redo the task while praying that it'll never get stuck this time.

EDIT: I also suspect that as long as there is a stuck "Generating..." Build mode for a certain model for a particular session (e.g. Grok Code Fast 1), the succeeding Build modes for the same model and session will be stuck.

I will refer to these stuck in "Generating..." Build modes as dangling Build mode.

I noticed this when I was able to run Build mode with Code Supernova 1M despite a dangling Build mode mode in Grok Code Fast 1.

That might explain why cutting the internet off works in resetting everything, because it practically kills all the dangling Build modes.

[lukidoescode]

Same here. Happning with Grok 4 Fast on OpenRouter. I also noticed that I cannot stop openai/gpt-5-mini, no matter how much I press ESC, the model will finish its output, unimpressed by my attempts to stop its lengthy explanations of what I have just witnessed it doing.

I'm using the latest opencode in tmux running inside wezterm.

[fredrikaverpil]

It's happening for me as well, but only with GitHub copilot models. I'm getting a "too many requests" error.
