Recently, artificial intelligence company Anthropic announced the addition of PDF file processing capabilities to its Claude 3.5 Sonnet model, which is now in public beta testing. Users can now utilize the model to analyze text and visual elements within PDF documents, including images, charts, and tables, suitable for various scenarios such as financial reports, legal documents, and document translation.
The PDF processing procedure in Claude 3.5 Sonnet is divided into three steps. Initially, the system extracts text content from the document. Subsequently, each page of the document is converted into an image for deeper analysis. This allows users not only to obtain textual information but also to understand visual information within the PDF file.
It is worth noting that Claude's PDF functionality can also be combined with other features, such as extracting specific information for use as tool input. It is important to note that uploaded files must be less than 32MB and contain no more than 100 pages. The system currently does not support encrypted or password-protected documents.
The cost of processing PDF files varies depending on the document's length and content density. Typically, each page consumes between 1,500 and 3,000 tokens, with no additional charges beyond the standard token fee. Users can preview and access this new feature through the Claude Chat function and API, which requires the specific request header "anthropic-beta: pdfs-2024-09-25". Anthropic plans to expand this feature to Amazon Bedrock and Google Vertex AI platforms in the future.
To enhance processing effectiveness, Anthropic recommends that users ensure the document contains clearly readable text and correct page layouts. Additionally, when referencing specific content, users should use the page numbers displayed in the PDF reader. In API usage, the PDF file should be placed before the text. If the document exceeds the limit, Anthropic suggests dividing it into smaller parts. Finally, when analyzing the same document multiple times, users can also consider using prompt caching to improve processing efficiency.
