pplx-embed-v2-context-9b-preview
Perplexity introduced pplx-embed-v2-context-9b-preview, a contextual embedding model that encodes document chunks with document-wide context and returns one embedding per chunk. It is publicly available as a preview; the provider cautions that weights and interface may change and that preview embeddings should not be mixed with later versions.
For buildersTest it on long documents where answer passages depend on distant context, comparing retrieval of both answer-bearing and supporting passages against your current chunk embeddings.
