opencode is using CPU for doing nothing!

[Jaaaky]

Description

While opencode is waiting for API limit rate - actually doing nothing -

Resource has been exhausted (e.g. check quota). [retrying in 18m 12s attempt #12]

It's actually using ~50% of single core on i9-14900 CPU

Plugins

nothing

OpenCode version

1.3.3

Steps to reproduce

I was working on a project using gemini api tier 1, quickly exhausted my limit, while waiting I noticed that opencode is using this much CPU on htop.
system performance is fine, I've many applications running including browsers, but only opencode is using this much CPU

$ ps -eo pid,ppid,cmd,%cpu --sort=-%cpu | grep -E 'PID|opencode'
    PID    PPID CMD                         %CPU
  76732   76729 opencode                    47.6
  82693   76732 /usr/bin/opencode run /home  0.3

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

• CPU: 30-40%+ i idle tauri://localhost #19106: Similar CPU usage issue (~30-40%+ CPU at idle/while waiting) reported for the opencode process

If your issue is distinct (specifically tied to the rate-limit retry waiting loop rather than general idle CPU usage), please clarify in this issue. Otherwise, consider adding your findings to the existing report.

This is absolutely still an open issue, and post-close comments on #4804 (it tops the Google search so most of your users are actually ending there when searching for CPU issues in opencode) prove it, there's comments up to very recently reporting that the original problem has not been closed. Opencode is hitting four cores at about 60-70% on my M1 MBP Max consistently which is A LOT for streaming blocks of text back and forth.

Same here, MacBook Apple M4 Pro, Tahoe, 24GB, now keeps heating and can only last for less than 3 hours by doing nothing, opencode is the only process takes high CPU usage (without task execution).

Same here on Linux Kubuntu 25.10 on Ryzen R9-5900HS with OpenCode version 1.14.25, it takes 50% of CPU with doing nothing. When model is running it takes almost 100% but model is remote so this is weird. Flatpak version 1.4.0 behaves the same almoast permnent CPU load.
