Patch Changes

  • #12145 e662f7c Thanks @hntrl! - Report streamed usage from the cumulative message_delta usage, as langchain-anthropic does, so input and cache tokens from server tool passes (e.g. web search) are counted and output tokens aren't double counted.

  • #12173 203cf6e Thanks @hntrl! - Support Claude Fable 5.2 and Mythos 5.2 profiles, always-on adaptive thinking, and the nameless computer toolset. Upgrade the Anthropic SDK and avoid forced tool choice for always-on thinking models.
