429: Quota exceeded for quota metric …
Gemini CLI's free tier has per-minute and per-day request quotas. Agentic sessions (many tool calls) hit the per-minute cap in bursts and the daily cap on long days; both reset automatically. Paid API keys raise the quotas.
A single “fix this repo” prompt can trigger dozens of requests. Free-tier daily quotas are sized for chat, not agent loops.
Gemini CLI is Google-model-only, so you can't repoint it. But OpenCode, Aider, and Cline do the same terminal-agent work on Standard Compute's flat-rate endpoint with no per-minute or daily quotas — a common setup is Gemini CLI for giant-context tasks, an unmetered agent for everything else.
Daily quotas reset at midnight Pacific time; per-minute quotas roll continuously.
