Original GitHub issue: https://github.com/ollama/ollama/issues/1705

I am trying to generate embeddings with the OllamaEmbeddings class but it takes forever on a Mac M2 Pro

I am embedding 22000 posts from a forum's threads; this is my config:

    from langchain.embeddings import OllamaEmbeddings
    from llama_index.llms.ollama import Ollama

    llm = Ollama(model="llama2:13b")
    
    ...
    
    service_context = ServiceContext.from_defaults(
    
        llm=llm,
    
        embed_model=OllamaEmbeddings(model="llama2:13b"),
    )

With OpenAI it takes minutes.

Hi there, new smaller embedding models are now available such as https://ollama.com/library/nomic-embed-text - this should be much faster now, and work is being done for batch embeddings
