Most search systems scan a document as text, losing tables and layout. Perplexity’s new models instead treat a page as an image, so they “see” a PDF, slide, or scan the way a person would, and a small model can search an index built by a much bigger one.
Perplexity released two open-weight models on October 7: a 0.6B version built for phones or edge devices, and a 9B version built for building a high-quality search index. Both convert text, images, and page images into the same shared numerical format, so a developer can build a large, accurate index with the 9B model, then run fast day-to-day searches with the small one. On MADQA, a test of answering questions from PDF documents, the 9B model scored 92.4%, the best result among retrieval-only systems tested, though it still trailed a more complex agentic search system.
Both are free for commercial use under the MIT license, available now on Hugging Face, with a hosted API still to come.
Key Capabilities:
- Mix and match: A 9B-built index can be searched using the smaller, cheaper 0.6B model.
- No OCR needed: Reads PDFs and slides as images directly, keeping tables and layout intact.
- Top score: 92.4% on MADQA, the best among pure retrieval systems Perplexity tested
