cd llama-gpt

You can now run LlamaGPT with any of the following models depending upon your hardware:

Model size	Model used	Minimum RAM required	How to start LlamaGPT
7B	Nous Hermes Llama 2 7B (GGML q4_0)	8GB	docker compose up -d
13B	Nous Hermes Llama 2 13B (GGML q4_0)	16GB	docker compose -f docker-compose-13b.yml up -d
70B	Meta Llama 2 70B Chat (GGML q4_0)	48GB	docker compose -f docker-compose-70b.yml up -d

You can access LlamaGPT at http://localhost:3000.

To stop LlamaGPT, run:

docker compose down

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.

Nous Hermes Llama 2 7B (GGML q4_0)

Device	Generation speed
M1 Max MacBook Pro (10 64GB RAM)	8.2 tokens/sec
Umbrel Home (16GB RAM)	2.7 tokens/sec
Raspberry Pi 4 (8GB RAM)	0.9 tokens/sec

Nous Hermes Llama 2 13B (GGML q4_0)

Device	Generation speed
M1 Max MacBook Pro (64GB RAM)	3.7 tokens/sec
Umbrel Home (16GB RAM)	1.5 tokens/sec

Meta Llama 2 70B Chat (GGML q4_0)

Unfortunately, we don't have any benchmarks for this model yet. If you have one, please open a pull request to add it to this table.

Roadmap and contributing

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

• Add CUDA and Metal support.
• Moving the model out of the Docker image and into a separate volume.
• Updating the front-end to show model download progress, and to 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.
