Operating System

Terminal

ghostty

more info, the "Claude*" models have been enabled in copilot feature setting, they works fine in VS code copilot plugin.

for me the Copilot's opus was able to plan, but could not write a file in build mode with

Now let me write the implementation:

~ Preparing write...
Tool execution aborted

oc v1.1.39, macOS 15.7.1, Ghostty 1.2.3

@OleksandrRakovets

On 1.1.39 the models work fine for me?

@OleksandrRakovets can u run this in ur terminal opencode export > session.json and then send me the session.json file it writes to

@rekram1-node

@rekram1-node thanks for the swift response!

could not reproduce on the new session now, it created and updated files 👌

sadly, cannot share the full session from the work project, these are the relevant parts from what happened earlier today

copilot-opus-failed-write.json

after that switched to Zen model and it finished the implementation

I am having same issue on windows 11 WSL2 Ubuntu 24.04 instance.
Both Github Copilot Cloude sonnect 4.5 and Opus 4.5 models having same issues. Sonnet was working fine but start thowing this error. switched to opus 4.5. It wrote few files and now start erroring "preparing write... Tool execution aborted"
I am using opencode 1.1.39

The Antropic suite works OK via GitHub provider. I have seen it few times display error message that time quota script calls exceeded, but after few seconds it continues working like it never stopped.

The Antropic suite via Antropic Plan does not work. The villain arc of Antropic will be studied...

@rekram1-node

Me and my colleagues often observe this warning. Messages are eventually re-tried and succeed

Could it be aborting a tool call in the middle of execution? @rekram1-node

for me the Copilot's opus was able to plan, but could not write a file in build mode with
Now let me write the implementation:

~ Preparing write...
Tool execution aborted
oc v1.1.39, macOS 15.7.1, Ghostty 1.2.3

I had the exact same issue (but on Windows). Reverting to 1.1.36 worked for me.

I'm having a similar issue, Claude Haiku 4.5 was working fine and then stopped, now it just says:

Not Found: Not Found

The logs show:

2026-01-30T190127.log:ERROR 2026-01-30T19:04:51 +0ms service=session.processor error=Not Found stack="AI_APICallError: Not Found\n    at <anonymous> (../../node_modules/.bun/@ai-sdk+provider-utils@3.0.20+d6123d32214422cb/node_modules/@ai-sdk/provider-utils/dist/index.mjs:950:18)\n    at processTicksAndRejections (native:7:39)" process

This happens for all Claude models, but all others are working fine.

@longwa

@longwa cannot replicate

My comment, won't help that much, only to confirm the same behavior on claude-* models, including non enabled ones:

Not Found: Not Found, 404 in the log.
Other models work

claude-* models worked part of the day until afternoon.

Behavior remains after deleting ~/.cache/opencode, ~/.local/share/opencode, ~/.local/state/opencode

Opened vscode again 🤕, claude-* models work.

@rekram1-node

@rekram1-node I had a coworker install opencode and try from scratch, same issue.

My issue is the same as @e-roux, it was working until late morning and then just stopped working. It still works via the Copilot plugin for IntelliJ so I assume it's not a rate limit or quota issue.

Can you share more info?

What version are you using?

Can you opencode export > session.json?

I just did fresh install too, I still can't replicate it seems, are you on a normal github setup? or github enterprise

update from my side after switching my machine

This afternoon on a Mac:

On GitHub, member of an organization (copilot subscription over the org).
Mac OS, opencode latest - 1.1.40 - from brew

I just tried with my private MacBook with a free plan from GitHub, same setup and same problematic.
Installed right now from anomalyco/tap and the issue seem to have disappeared (1.1.47).

Not clear to me what could explain this.

and last test on my corporate machine:

I deinstalled the official tap, installed anomalyco/tap/opencode -> ok, no error with haiku 4.5
deinstalled anomalyco/tap/opencode and installed again opencode using brew -> Not found: ... with haiku

=> looks either to be related to opencode 1.1.40 or the official brew package

use our brew tap not theirs, theirs isn't up to date

Use: anomalyco/tap/opencode

@rekram1-node

@rekram1-node that's exactly the issue.

brew install anomalyco/tap/opencode fixes this instead of brew install opencode

use our brew tap not theirs, theirs isn't up to date

Use: anomalyco/tap/opencode

Yep, that works! It's crazy that the other one worked until the middle of the day and then self-destructed.

use our brew tap not theirs, theirs isn't up to date

Use: anomalyco/tap/opencode

That solved the issue, I reinstalled opencode using the brew install anomalyco/tap/opencode and it started working again.

I'm having a similar issue, Claude Haiku 4.5 was working fine and then stopped, now it just says:
Not Found: Not Found
The logs show:
2026-01-30T190127.log:ERROR 2026-01-30T19:04:51 +0ms service=session.processor error=Not Found stack="AI_APICallError: Not Found\n    at <anonymous> (../../node_modules/.bun/@ai-sdk+provider-utils@3.0.20+d6123d32214422cb/node_modules/@ai-sdk/provider-utils/dist/index.mjs:950:18)\n    at processTicksAndRejections (native:7:39)" process

I have been facing the same Issue.
Github Copilot + Claude models keeps throwing "Not Found"
The same models on Anthropic subscription run fine.
Tried downgrading to 1.1.39, issue remains.

uninstalling and then running brew install anomalyco/tap/opencode solved it for me
