Description

Hello,

When the compaction starts, it automatically stops saying "Bad Request" but only for Claude Opus 4.5 (I'm using github copilot integration).
And now that we are here, any idea why I can't use Opus 4.6 with my github copilot integration? It's enabled for my github enterprise integration.

Any idea why?

Plugins

oh-my-opencode

OpenCode version

1.1.65

Steps to reproduce

  1. Start opencode
  2. Write a prompt
  3. Automatically starts the compaction
  4. Bad Request

Yes, the issue still persist, at least until 2h ago.
