[FR] Support for embedding models run through Ollama

[wwjCMP]

Through Ollama, there is a wide selection of embedding models available, and the operation is very efficient. Supporting Ollama's embedding models will effectively enhance the convenience of use.

Hi @wwjCMP and thanks for the feature request.

Any relevant documentation you can point me to would help implement this sooner.

Thanks

+1 for this. I'd love to make use of it as well.

I've successfully configured Smart Connections to work with a local Ollama server running Llama 3 for chat.

I'm not certain on how perfectly the Ollama API corresponds to the OpenAI API the choice of Custom Local model my selection expects. But it's close enough that the plugin and the LLM API are communicating correctly for chat.

The Ollama API docs are here: https://github.com/ollama/ollama/blob/main/docs/api.md#generate-embeddings

From the looks of it, you could get embeddings from the Ollama server instance using the same request format as you're currently making with the chat client with 2 changes:

• path: /api/embeddings
• model: nomic-embed-text (or any other embedding model pulled from https://ollama.com/library)

And a very abridged Ollama install for my macbook:

# install
brew install ollama

# pull models
ollama pull llama3
ollama pull nomic-embed-text

# serve
OLLAMA_ORIGINS=app://obsidian.md* ollama serve

Of any of the Obsidian LLM chat + RAG plugins, I think Smart connections has the best RAG and chat responses. I just wish local embedding computation didn't interfere with using my vault at the same time. I successfully got Ollama embeddings working in Obsidian Copilot if it's useful as an example.

Thanks!

+1 This feature would be awesome! I have a slow laptop, but a decent GPU server, which is sitting idle most of the time.

@brianpetro jan.ai creates a fully OpenAI compatible server API running locally at port 1337

Hi @matttrent, I am not able to get it work as Smart Connection prompted unable to connect. My suspect is caused by the path. Is /api/chat folder default installed by ollama? I am not able to find it in my mac mini.

[brianpetro]

@atmassrf if you're trying to use chat models (not embeddings), you may already be able to use the "custom local model" configuration to make it work with jan.ai

If that doesn't work, for example, if there are some small differences with the OpenAI API format, then we would have to make an adapter in https://github.com/brianpetro/jsbrains/tree/main/smart-chat-model to account for those differences.

[brianpetro]

@kennygokh Ollama embeddings aren't currently supported, but the chat models should work.

The ollama command I use to start the model looks like:

ollama run phi

That runs the phi model. Llama3 might look like:

ollama run llama3

Assuming it's already downloaded/installed via Ollama.

For improving the embedding speed, until the custom local embedding model adapter gets shipped, you might be interested in trying this https://www.youtube.com/watch?v=tGZ6J63UZmw&t=3s

+1 for this.

I think this is the feature request I am looking for. Can I use the embeddings created by Smart-Connection in Ollama? Then other plugins I use can know my notes. For some reason the embeddings created are .ajson instead of json?

Hey there! I'm trying to use llama3 for my chat with smart connections as well. I've got it running in the windows subsystem for linux, and I can confirm that Ollama is working correctly. The problem I'm having is that when I try to input llama3 as the model, I get an error saying "No Smart Connections", then it reverts the model to custom_local. Any ideas?
