Thanks for the report, @Cyborgscode.
Version 1.18.35 is OpenCode v1, which only gets fixes for critical bugs (data loss, security problems, or crashes or breakage with no workaround). Reasoning text showing up in the answer is annoying, but it doesn't meet that bar, so this is unlikely to be fixed in v1. It started suddenly without an OpenCode update, which suggests the model's output changed (it now sends the closing
</think>tag without the opening<think>).Please try upgrading to OpenCode v2 (the
@opencode/clinpm package,opencodecommand), where active development happens. Related reports (not exact duplicates), most likely first:If you think this is critical, or it also happens on v2, please reply here with the v2 version and the provider/model you're using.

Closing this as not planned. It was reported on v1 (1.18.35), and reasoning text showing up in the answer isn't a critical bug, so it won't be fixed in v1. We didn't hear that it's critical or that it also happens on v2.
If you see the same problem on OpenCode v2 (
@opencode/cli), please open a new issue with the v2 version and the provider and model you're using, or comment here. #54298 and #49673 may also be worth following. Thanks for reporting!
