Test that the Open LLM is running

First start the server by using only CPU:

export model_path="TheBloke/CodeLlama-13B-GGUF/codellama-13b.Q8_0.gguf"
python -m llama_cpp.server --model $model_path

Or with GPU support (recommended):

python -m llama_cpp.server --model TheBloke/CodeLlama-13B-GGUF/codellama-13b.Q8_0.gguf --n_gpu_layers 1

If you have more GPU layers available set --n_gpu_layers to the higher number.

To find the amount of available run the above command and look for llm_load_tensors: offloaded 1/41 layers to GPU in the output.

Test API call

Set the environment variables:

export OPENAI_API_BASE="http://localhost:8000/v1"
export OPENAI_API_KEY="sk-xxx"
export MODEL_NAME="CodeLlama"

Then ping the model via python using OpenAI API:

python examples/open_llms/openai_api_interface.py

If you're not using CodeLLama make sure to change the MODEL_NAME parameter.

Or using curl:

curl --request POST \
     --url http://localhost:8000/v1/chat/completions \
     --header "Content-Type: application/json" \
     --data '{ "model": "CodeLlama", "prompt": "Who are you?", "max_tokens": 60}'

If this works also make sure that langchain interface works since that's how gpte interacts with LLMs.

Langchain test

export MODEL_NAME="CodeLlama"
python examples/open_llms/langchain_interface.py

That's it 🤓 time to go back to and give gpte a try.
