Supported models

Currently, LlamaGPT supports the following models. Support for running custom models is on the roadmap.

Model name	Model size	Model download size	RAM required
Nous Hermes Llama 2 7B Chat (GGML q4_0)	7B	3.79GB	6.29GB
Nous Hermes Llama 2 13B Chat (GGML q4_0)	13B	7.32GB	9.82GB
Meta Llama 2 70B Chat (GGML q4_0)	70B	38.87GB	41.37GB

How to install

Install LlamaGPT on your umbrelOS home server

Running LlamaGPT on an umbrelOS home server is one click. Simply install it from the Umbrel App Store.

Install LlamaGPT on M1/M2 Mac

Make sure your have Docker and Xcode installed.

Then, clone this repo and cd into it:

git clone https://github.com/getumbrel/llama-gpt.git
cd llama-gpt

Run LlamaGPT with the following command:

./run-mac.sh --model 7b

To run 13B or 70B models, replace 7b with 13b or 70b respectively.

To stop LlamaGPT, do Ctrl + C in Terminal.

Install LlamaGPT anywhere else with Docker (CPU only)

You can run LlamaGPT on any x86 or arm64 system. Make sure you have Docker installed.

Then, clone this repo and cd into it:

git clone https://github.com/getumbrel/llama-gpt.git
cd llama-gpt

To run the 7B model, run:

docker compose up

To run the 13B model, run:

docker compose -f docker-compose-13b.yml up

To run the 70B model, run:

docker compose -f docker-compose-70b.yml up

Note: On the first run, it may take a while for the model to be downloaded to the /models directory. You may see lots of output like for a few minutes, which is normal:
llama-gpt-llama-gpt-ui-1       | [INFO  wait] Host [llama-gpt-api-13b:8000] not yet available...
After the model has been downloaded and loaded, and the API server is running, you'll see an output like:
llama-gpt-llama-gpt-api-13b-1  | INFO:     Uvicorn running on http://0.0.0.0:8000 (Press CTRL+C to quit)
You can then access LlamaGPT at http://localhost:3000.

To stop LlamaGPT, either do Ctrl + C or run:

docker compose down

Install LlamaGPT with Kubernetes

First, make sure you have a running Kubernetes cluster and kubectl is configured to interact with it.

Then, clone this repo and cd into it.

To deploy to Kubernetes first create a namespace:

kubectl create ns llama

Then apply the manifests under the /deploy/kubernetes directory with

kubectl apply -k deploy/kubernetes/. -n llama

Expose your service however you would normally do that.

OpenAI compatible API

Thanks to llama-cpp-python, a drop-in replacement for OpenAI API is available at http://localhost:3001. Open http://localhost:3001/docs to see the API documentation.

Benchmarks

We've tested LlamaGPT models on the following hardware with the default system prompt, and user prompt: "How does the universe expand?" at temperature 0 to guarantee deterministic results. Generation speed is averaged over the first 10 generations.

Feel free to add your own benchmarks to this table by opening a pull request.

Roadmap and contributing

We're looking to add more features to LlamaGPT. You can see the roadmap here. The highest priorities are:

Moving the model out of the Docker image and into a separate volume.
Add Metal support for M1/M2 Macs.
Add CUDA support for NVIDIA GPUs (work in progress).
Add ability to load custom models.
Allow users to switch between models.
Making it easy to run custom models.

If you're a developer who'd like to help with any of these, please open an issue to discuss the best way to tackle the challenge. If you're looking to help but not sure where to begin, check out these issues that have specifically been marked as being friendly to new contributors.
