Description

There are some issues with the google-vertex/gemini-3-pro-preview model.

  • the plan mode makes the model go into existential crisis, as it appears it doesn't know when to stop and just wants to build the feature and questions its existence when it can't
  • the compact command is treated by the model as a subterfuge to just start working on whatever todos it finds in the repo
  • the sessions are not automatically renamed

OpenCode version

1.0.98

I have similar issues with that model.

For plan mode issue - it happens rarely, and it's fixable if add to prompt 'only plan, no execution'.
So i assume it's not opencode issue. It looks like model problem.

Compact issue - well i didn't have a chance to try it yet since this model has 2m context window :)

Session naming issue - that's the biggest one for now. Doesn't work at all!!
