Spotted this in llm logs -c --json:

      "usage": {
        "completion_tokens": 186,
        "prompt_tokens": 48711,
        "total_tokens": 48897,
        "completion_tokens_details": "CompletionTokensDetails(audio_tokens=0, reasoning_tokens=0, accepted_prediction_tokens=0, rejected_prediction_tokens=0)",
        "prompt_tokens_details": "PromptTokensDetails(audio_tokens=0, cached_tokens=48512)"
      }

        "total_tokens": 49269,
