In an announcement perhaps timed to divert attention away from OpenAI’s Operator, Anthropic Thursday unveiled a new feature for its developer API called Citations, which lets devs “ground” answers from its Claude family of AI in source documents such as emails.
Anthropic says Citations allows its AI models to provide detailed references to “the exact sentences and passages” from docs they use to generate responses. As of Thursday afternoon, Citations is available in both Anthropic’s API and Google’s Vertex AI platform.
As Anthropic explains in a blog post with Citations, devs can add source files to have models automatically cite claims that they inferred from those files. Citations is particularly useful in document summarization, Q&A, and customer support applications, Anthropic says, where the feature can nudge models to insert source citations.
Citations isn’t available for all of Anthropic’s models — only Claude 3.5 Sonnet and Claude 3.5 Haiku. Also, the feature isn’t free. Anthropic notes that Citations may incur charges depending on the length and number of the source documents.
Based on Anthropic’s standard API pricing, which Citations uses, a roughly-100-page source doc would cost around $0.30 with Claude 3.5 Sonnet, or $0.08 with Claude 3.5 Haiku. That may well be worth it for devs looking to cut down on hallucinations and other AI-induced errors.
