Gemini CLI automatically optimizes API costs through token caching when using
|
|
|
|
|
API key authentication (Gemini API key or Vertex AI). This feature reuses
|
|
|
|
|
previous system instructions and context to reduce the number of tokens
|
|
|
|
|
processed in subsequent requests.

You can view your token usage and cached token savings using the `/stats`
|
|
|
|
|
command. When cached tokens are available, they will be displayed in the stats
|
|
|
|
|
output.
