Expand description

Usage metadata returned by the server on messages.

Contains token counts for the prompt, response, cached content, tool use, and thinking, with optional per-modality breakdowns.

Fields§

§prompt_token_count: Option<u32>

Number of tokens in the prompt.

§cached_content_token_count: Option<u32>

Number of tokens in the cached portion of the prompt.

§response_token_count: Option<u32>

Total number of tokens across all generated response candidates.

Live reports this as responseTokenCount; generateContent as candidatesTokenCount. Both land here.

§tool_use_prompt_token_count: Option<u32>

Number of tokens present in tool-use prompt(s).

§thoughts_token_count: Option<u32>

Number of tokens of thoughts for thinking models.

§total_token_count: Option<u32>

Total token count for the generation request (prompt + response).

§prompt_tokens_details: Vec<ModalityTokenCount>

Per-modality breakdown of prompt tokens.

§cache_tokens_details: Vec<ModalityTokenCount>

Per-modality breakdown of cached content tokens.

§response_tokens_details: Vec<ModalityTokenCount>

Per-modality breakdown of response tokens.

§tool_use_prompt_tokens_details: Vec<ModalityTokenCount>

Per-modality breakdown of tool-use prompt tokens.
