Github Copilot burns premium quota for non-premium models

[antoine-js]

Description

It started with a recent update of opencode. But now for example if I use GPT 4.1 which is a not a premium model of Copilot, it will consume my premium requests.

I did not try all versions but rolling back to opencode 1.0.200 fixes it.

This is pretty bad because people might consume their Copilot subscription super fast this month without realizing maybe.
