anthropic 0.39.0 removed "legacy client.count_tokens() method". We only call create_tokens_usage for message using legacy completion model, like claude-2.1. Tried to use a new API beta.messages.count_tokens but got 400 error from the API.

Consider the rare usage of legacy models, I set the token to 0 and we could discuss if we want to deprecate the support in future.
