Anthropic releases Claude Opus 4.8 with faster mode and updated token defaults

By PulseAugur Editorial · [2 sources] ·

Anthropic has released Claude Opus 4.8, a new iteration of its large language model. This update includes a "fast mode" option for organizations that have enabled the feature, and the default max_tokens setting has been adjusted to align with each model's maximum output. The llm-anthropic Python library has been updated to version 0.25.1 to support these changes, with LangChain also releasing an update to its anthropic integration (langchain-anthropic==1.4.4) to incorporate these improvements and address tool-call ID normalization.
