In my linux cachyos, I have opencode 1.0.162. When I do a simple hi with Cerebras GLM 4.7, I get the following

This issue might be a duplicate of existing issues. Please check:
These issues share similar validation error patterns (invalid_union, invalid_type errors) and suggest a broader issue with how responses from certain AI providers are being validated. Feel free to ignore if your specific case differs.

I suggest updating OpenCode and trying again

@goniz 1.0.162 is the latest (at least with paru)
goniz commentedon Jan 9, 2026
Latest version is actually 1.1.8.
Since OpenCode has a very fast update rate, I suggest you uninstall the paru version and use the curl installer from OpenCode and the cli will take care of the updates for you.
