Universal PDF Support

OpenRouter has introduced Universal PDF Support, enabling compatibility with any Large Language Model (LLM) available on its platform and handling all types of PDFs, including image-only scans. This feature automatically utilizes native PDF support for providers like Gemini, Anthropic, and OpenAI and transmits embedded images from PDFs directly to multimodal models. Users can enhance functionality by combining it with web search or Auto Router, and it is accessible via API or directly from the OpenRouter Chatroom, supporting multiple PDFs and models in a single request. The service offers two PDF processing engines: mistral-ocr, which provides OCR support with text and embedded images extraction for $2 per 1000 pages, and pdf-text, which offers free text-only extraction without OCR or image support. Comprehensive documentation and implementation guidance are available online, alongside a video demo for more detailed insight.
