📄 Description

Summary

Adds PerplexityEmbeddings to the LangChain Python embeddings integrations docs. PerplexityEmbeddings was merged into langchain-perplexity in langchain-ai/langchain#37082 (closing #36726) but isn't yet surfaced on the embeddings index page.

Changes

  • embeddings/index.mdx — adds PerplexityEmbeddings to the Top integrations table and a Perplexity card to the All embedding models grid (alphabetically between PredictionGuard and PremAI).
  • embeddings/perplexity.mdx (new) — full integration page modeled on nomic.mdx / aimlapi.mdx: setup, credentials, installation, instantiation, indexing/retrieval with InMemoryVectorStore, direct usage of embed_query/embed_documents, async usage, and a note about Perplexity's base64-encoded int8 embedding format. Models documented: pplx-embed-v1-4b (default) and pplx-embed-v1-0.6b, matching the merged class.
  • providers/perplexity.mdx — adds an ## Embedding models section with a usage pointer and a row in the components reference table for PerplexityEmbeddings.

Notes

  • No docs.json changes — embeddings integration pages are auto-discovered (only one embeddings page is individually registered in the sidebar, and that's a JS one).
  • Reference link uses https://reference.langchain.com/python/langchain-perplexity/embeddings/PerplexityEmbeddings, matching the convention used for other partner embeddings (Nomic, Voyage AI, Mistral, etc.).
  • Builds on the recently-merged #3798 which surfaced the Search retriever + tool pages.
