Great overall but we need to do something about token usage. We upgraded our engineering team to Copilot and easily run into $1000+ per developer. It's not even middle of the month... OpenCode is significantly more efficient. At this rate GitHub Copilot is not sustainable for us.

| Field | Value |
| --- | --- |
| App version | 0.2.32 |
| OS | macOS 26.5.1 |
| Theme | GitHub |
| Path | /chat |
| Tenure | Week 2 |

No file, test, or code entry point is mentioned. Start by reproducing the token usage on the /chat path with app version 0.2.32 on macOS, then determine a measurable target for reducing usage; the issue is done only when that target is defined and verified.
