Originally created by @iyang1016 on GitHub (Sep 26, 2025).

Originally assigned to: @thdxr on GitHub.

Issue Description

The high RAM usage seems related to the Bun runtime.

Environment Details

  • OS: Windows 11
  • Runtime: Bun and Go installed
  • Observation: The Bun process shows unusually high memory consumption

Additional Context

  • Previous versions did not use as much RAM
  • This issue started occurring after recent updates that use Bun
  • Memory usage appears to be specifically tied to Bun processes

Question

Are there recommended Bun config changes or troubleshooting steps for memory control that could help resolve this issue?

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

  • #2585: Reports massive memory use (29GB RAM) when opening opencode with large files - similar symptoms of high RAM usage
  • #496: Describes absurd amount of CPU and memory usage during path completion - also mentions high memory consumption
  • #804: Reports memory leak that eats up gigabytes of RAM until system crash (closed but similar behavior)

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

Hmm I don't think anything should've changed in this department, what model are you using?

We did include reasoning by default for gpt-5 and that will make thinking blocks render but Idk if that'd be the issue here since I imagine that'd be eating cpu rather than ram i dont see anything else in recent release affecting it.

Dax has been working on rewriting the tui and it should address a whole bunch of performance issues

Update: I tried rolling back to v0.11.7 and noticed that Bun's RAM usage is much lower compared to v0.11.8. On v0.11.8, Bun's memory usage keeps increasing and can reach almost 4GB even on moderate usage, but in v0.11.7, RAM usage stays well below 600MB. This suggests the recent update introduced a significant memory regression.

also experiencing this on my m1 mac (using sonnet 4.5 model from anthropic)

if i notice, the memory high usage will occured if opencode trying to read file(s), (start with permission to read),
after it read all of my file, the memory gone up and even if it already done reading, the memory still didnt go down.

So, what i do was to quit session and then start opencode again using /session

@edwarbudiman could be the lsp servers, what kinda project is it? You can disable them if u need to

lsp: {
serverId: {
disabled: true
}
}

for full list of servers see here: https://opencode.ai/docs/lsp/#built-in

hmm, interesting @rekram1-node
as per 0.15.3 version, i try to re-create the situation, the memory still okay,
will let you know if something happened ever again.
thanks

@rekram1-node @thdxr Still the memory usage is very high I am using "1.0.218" version of opencode and the RAM opencode consumes is very high.

When can we expect it to be fixed, as it remains a critical blocker and opencode crashes after sometime

I just have playwright MCP enabled for debugging

+1

I just had the same problem! I have 64GB of RAM, and out of nowhere, Bun started using 40GB of RAM. That's a big problem with Bun. I did some research, and there are issues with Bun related to this.
