NomicEmbeddings embedding model.

Example

from langchain_nomic import NomicEmbeddings

model = NomicEmbeddings()

Initialize NomicEmbeddings model.

Parameters:

  • model (str) – model name

  • nomic_api_key (str | None) – optionally, set the Nomic API key. Uses the NOMIC_API_KEY environment variable by default.

  • dimensionality (int | None) – The embedding dimension, for use with Matryoshka-capable models. Defaults to full-size.

  • inference_mode (str) – How to generate embeddings. One of remote, local (Embed4All), or dynamic (automatic). Defaults to remote.

  • device (str | None) – The device to use for local embeddings. Choices include cpu, gpu, nvidia, amd, or a specific device name. See the docstring for GPT4All.__init__ for more info. Typically defaults to CPU. Do not use on macOS.

  • vision_model (str | None)
