🚀 Get started now and unlock the full potential of Llama 3.1 on Hivenet Compute!

Requirements

• 1 Compute X-Small instance with Ubuntu v24.04 LTS template
• Hugging Face token with access to Llama 3.1

Dependencies

Ensure the following dependencies are installed:

• pip
• miniconda
• vllm

Installing dependencies

To prevent loss of installed packages, all dependencies should be installed inside the /home/ubuntu/workspace directory.

Connect to your Compute instance

First, establish an SSH connection to your Compute instance:

ssh -i ~/.ssh/id_rsa -o "ProxyCommand=ssh bastion@ssh.hivecompute.ai %h" ubuntu@d348351b-a04c-4b98-9d1a-2e474623395b.ssh.hivecompute.ai

Install miniconda

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O install_miniconda.sh
bash install_miniconda.sh -b -p /home/ubuntu/workspace/opt/conda
export PATH=/home/ubuntu/workspace/opt/conda/bin:$PATH
conda init

Disconnect and reconnect (CTRL+D) for the changes to take effect.

Install vllm

pip install vllm

Serving Llama 3.1 8B

Llama 3.1 models have a maximum context length of 128K tokens. On an RTX 4090 (24GB VRAM):

• 16GB is used for model parameters (BF16 precision)
• 8GB is available for the KV cache
• This allows for up to 59K tokens in context length
• For longer context lengths, use FP8 quantization or a larger Compute instance

Running in full precision (59K Tokens)

export HF_TOKEN=<YOUR_HUGGING_FACE_TOKEN>nohup vllm serve meta-llama/Llama-3.1-8B-Instruct --download-dir /home/ubuntu/workspace --gpu-memory-utilization 1 --max-model-len 59000 &

Monitor logs to confirm endpoints are available:

tail -f nohup.out

Look for output similar to:

3. Test the model locally

curl -X POST "http://localhost:8000/v1/chat/completions" -H "Content-Type: application/json" --data '{"model": "meta-llama/Llama-3.1-8B-Instruct","messages":[{"role": "user", "content": "what is AI?"}],"max_tokens": 50}'

Running in FP8 precision (128K Tokens)

To use the full 128K context length, run:

‍export HF_TOKEN=<YOUR_HUGGING_FACE_TOKEN>
nohup vllm serve meta-llama/Llama-3.1-8B-Instruct --download-dir /home/ubuntu/workspace --gpu-memory-utilization 1 --max-model-len 128000 --dtype half --quantization fp8 --kv-cache-dtype fp8 &

Monitor logs and wait until the openai endpoints are exposed:

Exposing OpenAI-compatible endpoints

To allow external access, you have two options:

1. FRP (if you have a publicly accessible server/VM)
2. Ngrok (if you don’t have a public instance)

Using Ngrok for External Access

• Create an account at ngrok
• Log in and get your authentication token
• Download and install Ngrok

wget https://bin.equinox.io/c/bNyj1mQVY4c/ngrok-v3-stable-linux-amd64.tgz
sudo tar -xvzf ngrok-v3-stable-linux-amd64.tgz -C /usr/local/bin

• Add your token


ngrok config add-authtoken <YOUR_NGROCK_TOKEN>

• Claim a static domain from your ngrok account
• Start Ngrok

nohup ngrok http --url=<YOUR_NGROK_STATIC_DOMAIN> 8000 &

Testing external access

curl https://<YOUR_NGROK_STATIC_DOMAIN>/v1/models
{"object":"list","data":[{"id":"meta-llama/Llama-3.1-8B-Instruct","object":"model","created":1733495850,"owned_by":"vllm","root":"meta-llama/Llama-3.1-8B-Instruct","parent":null,"max_model_len":128000,"permission":[{"id":"modelperm-ecfa0d0e5dd04d4c973e9fc134d00d98","object":"model_permission","created":1733495850,"allow_create_engine":false,"allow_sampling":true,"allow_logprobs":true,"allow_search_indices":false,"allow_view":true,"allow_fine_tuning":false,"organization":"*","group":null,"is_blocking":false}]}]}

curl -X POST "https://<YOUR_NGROK_STATIC_DOMAIN>/v1/chat/completions" -H "Content-Type: application/json" --data '{"model": "meta-llama/Llama-3.1-8B-Instruct","messages":[{"role": "user", "content": "what is AI?"}],"max_tokens": 50}'

That’s it! You now have Llama 3.1 8B running on Compute with OpenAI-compatible endpoints. If you need more context length, tweak precision settings or upgrade your instance.
