The introduction of Citations on the Anthropic API enhances the capabilities of Claude by allowing it to ground its answers in source documents, providing precise references for the information used in its responses. This feature aims to improve the trustworthiness and verifiability of AI-generated outputs by automatically citing claims based on user-provided source materials. Citations is now generally available on the Anthropic API and Google Cloud’s Vertex AI, making it easier for developers to create AI solutions across various use cases, including document summarization, complex Q&A, and customer support.
The process involves chunking user-provided documents into sentences, which Claude uses to generate responses with accurate citations, minimizing the risk of hallucinations. Notably, internal evaluations indicate that the built-in citation capabilities enhance recall accuracy by up to 15%. Prominent users like Thomson Reuters and Endex have reported significant improvements in their AI systems’ reliability and accuracy due to this feature. Citations utilizes a standard token-based pricing model, ensuring that users are only charged for input tokens without additional costs for the output of quoted text. The feature is available for the new Claude 3.5 Sonnet and Claude 3.5 Haiku models, with documentation available for users to get started.
