inputTokenDetails

Breakdown of input token counts. Does not need to sum to full input token count. Does not need to have all keys. Example:

{
    "audio": 10,
    "cache_creation": 200,
    "cache_read": 100,
}

May also hold extra provider-specific keys.

• Throws LangChainInvalidDataException: if the JSON field has an unexpected type (e.g. if the server responded with an unexpected value).
