What happened

AI Search is now generally available, Cloudflare Blog announced. It embeds image pixels directly for visual search, runs optical character recognition on scanned PDFs, accepts files up to 10 MiB, and works with any chat model. Cloudflare’s AI Search combines Workers AI, Vectorize, R2, and Browser Run into a fully managed index and retrieval pipeline.

New: multimodal (able to work with more than one kind of input, such as text and images) embedding and retrieval An image is more than the sentence used to describe it. Product texture, screenshot state, chart relationships, document layout, and fine visual detail can all disappear when pixels are compressed into a caption.

AI Search now preserves both signals: it embeds image pixels directly for visual retrieval while retaining captions for textual understanding. To keep these richer representations efficient, AI Search leverages Matryoshka Representation Learning (MRL), allowing smaller embeddings to retain useful information while keeping storage manageable and search fast.
