[Bug] Anthropic API: Incorrect token usage reporting and telemetry discrepancies

Bug Description
I need to send a detailed error report to the Anthropic team. Technical context: the logs and usage records of the LLMs are showing significant discrepancies — the reported data does not accurately reflect my actual usage, indicating a possible telemetry failure, incorrect measurement of token consumption, or inconsistencies in how sessions are being monitored by the system. It is critical that this situation is thoroughly investigated, as it may affect cost control, traceability, and performance evaluation. I request an urgent analysis based on this context.
