LLM Usage Metrics

Antigravity Source

Default location

Section titled “Default location”
  • $GEMINI_CLI_HOME/antigravity-cli/conversations/*.db when GEMINI_CLI_HOME is set
  • ~/.gemini/antigravity-cli/conversations/*.db

Override

Section titled “Override”
Terminal window
llm-usage daily --source antigravity --antigravity-dir /path/to/antigravity/conversations

antigravity is directory-backed, so generic source directory overrides also work:

Terminal window
llm-usage daily --source-dir antigravity=/path/to/antigravity/conversations

Parsing notes

Section titled “Parsing notes”

The adapter reads Antigravity CLI SQLite conversation databases in read-only mode. Token usage is stored in protobuf blobs: input and cache-read tokens map directly, output includes thinking tokens (they are billed at the output rate) with reasoning kept as a breakdown, and repeated response ids are counted once. The usage message’s first field repeats the request’s model enum and is not counted as tokens. Claude model names carry Antigravity’s effort suffix (claude-opus-5-5-medium) and are priced as the base model.
