Gemini CLI doesn't have the so-called "intelligence degradation" problem at all - it's just that most people haven't chosen the correct way to use it.

The so-called intelligence degradation that people refer to is what some call the "Pro model," automatically switching to the "Flash model."

This isn't intelligence degradation - this is Gemini CLI's automatic scheduling mechanism. Real intelligence degradation is CloseAI, whereas as long as your IP isn't pure, o3 immediately goes from 0-second thinking to GPT3.5.

Gemini CLI's automatic scheduling mechanism will definitely trigger model switching in the following situations:

  • Simple tasks: Basic operations like npm start, ls -la automatically select the Flash model

  • Complex tasks: Code architecture design, multi-module integration testing, etc., will invoke the Pro model

  • Tool call failures: When command execution fails, subsequent error analysis uses the Flash model

Additionally, it will automatically switch after two or more consecutive slow responses. Of course, there are also issues with Google's own systems - when user usage and request volume surge, the system will also trigger switching.

So, how do you prevent Gemini CLI from automatically switching?
