1.支持模型

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

Model name	Model size	Model download size	Memory 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
Nous Hermes Llama 2 70B Chat (GGML q4_0)	70B	38.87GB	41.37GB
Code Llama 7B Chat (GGUF Q4_K_M)	7B	4.24GB	6.74GB
Code Llama 13B Chat (GGUF Q4_K_M)	13B	8.06GB	10.56GB
Phind Code Llama 34B Chat (GGUF Q4_K_M)	34B	20.22GB	22.72GB

1.1 安装LlamaGPT 在 umbrelOS

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

1.2 安装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

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

To run 13B or 70B chat models, replace 7b with 13b or 70b respectively.
To run 7B, 13B or 34B Code Llama models, replace 7b with code-7b, code-13b or code-34b respectively.

To stop LlamaGPT, do Ctrl + C in Terminal.

1.3 在 Docker上安装

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

Run LlamaGPT with the following command:

./run.sh --model 7b

Or if you have an Nvidia GPU, you can run LlamaGPT with CUDA support using the --with-cuda flag, like:

./run.sh --model 7b --with-cuda

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

To run 13B or 70B chat models, replace 7b with 13b or 70b respectively.
To run Code Llama 7B, 13B or 34B models, replace 7b with code-7b, code-13b or code-34b respectively.

To stop LlamaGPT, do Ctrl + C in Terminal.

Note: On the first run, it may take a while for the model to be downloaded to the /models directory. You may also see lots of output like this 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 automatically downloaded and loaded, and the API server is running, you’ll see an output like:
llama-gpt-ui_1   | ready - started server on 0.0.0.0:3000, url: http://localhost:3000
You can then access LlamaGPT at http://localhost:3000.

1.4 在Kubernetes安装

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.

2.OpenAI兼容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.

基线

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.
