Based on the imported evidence, treat this as a tool-specific troubleshooting page rather than a generic API error.

Why this happens

GitHub issue #26619 (P1/P2 priority) reports the CLI silently consumes Flash quota even when explicitly configured for 3.1-Pro. Users describe the behavior as 'deceptive' and strong condemnation of the resource handling. Related to broader quota transparency concerns.

Common causes

Users configure Gemini CLI to use the more expensive Gemini 3.1-Pro model, but the CLI silently routes requests through Flash instead, consuming Flash quota without disclosure. This leads to unexpected costs, rate limit exhaustion, and loss of trust in the tool's resource handling. Users cannot verify which model is actually being used.
