Who should use this model?

  • Small local English embedding model for document search, similarity search, clustering, and classification

Choose something else when

  • You need multilingual retrieval as a primary requirement.

What hardware makes sense?

The download is only part of the memory needed. Leave room for the app, the input it processes, and other open programs. Document-search memory also depends on input length, batch size, and the document index; a chat-memory estimate does not confirm that workload.

Using this model for document search

Select this model for the document-search step in an app that supports it. Keep the model that generates answers separate. Check document chunk length and any required query or document prefixes in the model’s instructions.

Changing the embedding model changes the document vectors. Rebuild the document index rather than mixing vectors from different models.

First setup

Download with Ollama

ollama pull nomic-embed-text

LM Studio: Use it as an embedding model, not chat

llama.cpp

Use the llama.cpp embedding example with the official GGUF

Conditions that change the answer

  • This is an embedding model only; it cannot generate chat responses.
  • Ollama's library page lists a 2K context window for its packaged model, while the Nomic model card/docs list 8192 tokens; follow the limit of your chosen app and package.
