Anthropic recently announced that its Claude 3.5 Sonnet model has added PDF file processing capabilities and has now entered the public testing phase. This function allows users to analyze text, images, charts and tables in PDF documents, and is applicable to a wide range of applications, including financial reports, legal documents and document translation. The editor of Downcodes will explain in detail the features, usage and precautions of this new feature to help you better understand and use this powerful AI tool.
Claude 3.5 Sonnet's PDF processing process is divided into three steps. First, the system extracts textual content from the document. Each page of the document is then converted into an image for deeper analysis. In this way, users can not only obtain text information, but also gain insight into the visual information in PDF files.
It’s worth mentioning that Claude’s PDF functionality can also be used in conjunction with other features, such as extracting specific information and using it as tool input. It should be noted that the uploaded file must be less than 32MB and the number of pages must not exceed 100 pages. The system does not currently support encrypted or password-protected documents.
The cost of processing PDF files will vary depending on the length and content density of the document. Typically, 1,500 to 3,000 tokens are consumed per page of document at no additional charge above the standard token fee. Users can use this new feature through the Claude Chat feature preview and API access. The specific request header "anthropic-beta: pdfs-2024-09-25" needs to be used in the API request. Anthropic plans to expand this functionality to Amazon Bedrock and Google Vertex AI platforms in the future.
To improve processing, Anthropic recommends users ensure that documents have clear, readable text and that the page layout is correct. Additionally, when referencing specific content, users should use the page numbers displayed in the PDF reader. When using the API, the PDF file should be placed before the text. If the document is larger than the limit, Anthropic recommends splitting it into smaller parts. Finally, when analyzing the same document multiple times, users may also consider using hint caching to improve processing efficiency.
Claude 3.5 Sonnet's PDF processing function provides users with a more efficient and convenient way to process documents, and I believe it will be widely used in more fields in the future. Anthropic’s continued improvements and optimizations are also worth looking forward to!
