A new service has been launched to demonstrate the potential of extracting structured data from unstructured sources like text and PDF documents, utilizing large language models. This hosted application, although not for production use, allows developers to experiment with the latest tools to create their own data extraction workflows. It supports various file types and models, enabling the definition of extraction schemas in natural language and the sharing of extractors among users. The service relies on features such as long context windows, function calling capabilities, and improved support for handling different file types and schema formats. An example of its application includes extracting financial data from a public company's earnings call transcript, showcasing how structured data can be derived from natural language text. This service is integrated with LangChain's tools and can be connected to larger workflows, providing developers with a powerful tool to explore data extraction possibilities.
