Last week Anthropic released version 0.39.0 of its python sdk, which enabled support for Python 3.13. This release deleted a legacy `client.count_tokens` method, which we currently access during init of the `Anthropic` LLM. Anthropic has replaced this functionality with the [client.beta.messages.count_tokens() API](https://github.com/anthropics/anthropic-sdk-python/pull/726). To enable support for `anthropic >= 0.39.0` and Python 3.13, here we drop support for the legacy token counting method, and add support for the new method via `ChatAnthropic.get_num_tokens_from_messages`. To fully support the token counting API, we update the signature of `get_num_tokens_from_message` to accept tools everywhere. --------- Co-authored-by: Bagatur <22008038+baskaryan@users.noreply.github.com>
