To use in OpenCode, you can update the models it has:

    opencode models --refresh

Then /models and choose Gemini 3.1 Pro

You can use the model through OpenCode Zen right away and avoid that Google UI craziness.

It is quite pricey! Good speed and nailed all my tasks so far. For example:

    @app-api/app/controllers/api/availability_controller.rb 
    @.claude/skills/healthie/SKILL.md 

    Find Alex's id, and add him to the block list, leave a comment 
    that he has churned and left the company. we can't disable him 
    properly on the Healthie EMR for now so 
    this dumb block will be added as a quick fix.

Result was:

    29,392 tokens
    $0.27 spent

So relatively small task, hitting an API, using one of my skills, but a quarter. Pricey!

I don't see it even after refresh. Are you using the opencode-gemini-auth plugin as well?

		No I am not just vanilla OpenCode. I do have OpenCode Zen credits, and I did opencode login whatever their command is to auth against opencode itself. Maybe that's the reason I see these premium models.
