-## Install GPT4All Python

-`gpt4all` gives you access to LLMs with our Python client around [`llama.cpp`](https://github.com/ggerganov/llama.cpp) implementations. 
-
-Nomic contributes to open source software like [`llama.cpp`](https://github.com/ggerganov/llama.cpp) to make LLMs accessible and efficient **for all**.
-
-```bash
-pip install gpt4all
-```
-
-```python
-from gpt4all import GPT4All
-model = GPT4All("Meta-Llama-3-8B-Instruct.Q4_0.gguf") # downloads / loads a 4.66GB LLM
-with model.chat_session():
-    print(model.generate("How can I run LLMs efficiently on my laptop?", max_tokens=1024))

 ## How It Works
 
 Obsidian for Desktop syncs your Obsidian notes to your computer, while LocalDocs integrates these files into your LLM chats using embedding models. These models find semantically similar snippets from your files to enhance the context of your interactions.

 ## How It Works
 
 A LocalDocs collection uses Nomic AI's free and fast on-device embedding models to index your folder into text snippets that each get an **embedding vector**. These vectors allow us to find snippets from your files that are semantically similar to the questions and prompts you enter in your chats. We then include those semantically similar snippets in the prompt to the LLM.

 We support models with a `llama.cpp` implementation which have been uploaded to [HuggingFace](https://huggingface.co/).
 
-### Which embedding models are supported?
-
-We support SBert and Nomic Embed Text v1 & v1.5.
-
 ## Software
 
 ### What software do I need?
 
 All you need is to [install GPT4all](../index.md) onto you Windows, Mac, or Linux computer.
 
-### Which SDK languages are supported?
-
-Our SDK is in Python for usability, but these are light bindings around [`llama.cpp`](https://github.com/ggerganov/llama.cpp) implementations that we contribute to for efficiency and accessibility on everyday computers.
-
 ### Is there an API?
 
 Yes, you can run your model in server-mode with our [OpenAI-compatible API](https://platform.openai.com/docs/api-reference/completions), which you can configure in [settings](../gpt4all_desktop/settings.md#application-settings)
 
-### Can I monitor a GPT4All deployment?
-
-Yes, GPT4All [integrates](../gpt4all_python/monitoring.md) with [OpenLIT](https://github.com/openlit/openlit) so you can deploy LLMs with user interactions and hardware usage automatically monitored for full observability.
-
-### Is there a command line interface (CLI)?
-
-[Yes](https://github.com/nomic-ai/gpt4all/tree/main/gpt4all-bindings/cli), we have a lightweight use of the Python client as a CLI. We welcome further contributions!
