Perplexity Opens Multimodal Retrieval Embeddings—Why Document Chunks Need Context
On 2026-11-03 09:09:18 Asia/Shanghai, pplx-announcements posted open-weight vision-language embeddings pplx-embed-v2-context (9B / 0.6B). Contextual mode encodes chunks with surrounding document context; both sizes share a 1024-d MRL prefix. Paper arXiv:2610.38854 was submitted 2026-10-28—not a same-day first appearance. Ordinary vs contextual chunking and encode_queries vs encode are laid out below. Card SOTA lines are self-reported; we have not retested recall, VRAM, or multilingual retrieval.
