Subnet 1 - the first installment of Hypertensor subnets.
Run large language models at home, BitTorrent-style.
Fine-tuning and inference up to 10x faster than offloading
Generate text with distributed Llama 2 (70B), Falcon (40B+), BLOOM (176B) (or their derivatives), and fine‑tune them for your own tasks — right from your desktop computer or Google Colab:
from transformers import AutoTokenizer
from petals import AutoDistributedModelForCausalLM
# Choose any model available at https://health.petals.dev
model_name = "petals-team/StableBeluga2" # This one is fine-tuned Llama 2 (70B)
# Connect to a distributed network hosting model layers
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoDistributedModelForCausalLM.from_pretrained(model_name)
# Run the model as if it were on your computer
inputs = tokenizer("A cat sat", return_tensors="pt")["input_ids"]
outputs = model.generate(inputs, max_new_tokens=5)
print(tokenizer.decode(outputs[0])) # A cat sat on a mat...🔏 Privacy. Your data will be processed with the help of other people in the public swarm. Learn more about privacy here. For sensitive data, you can set up a private swarm among people you trust.
🦙 Want to run Llama 2? Request access to its weights at the ♾️ Meta AI website and 🤗 Model Hub, then run huggingface-cli login in the terminal before loading the model. Or just try it in our chatbot app.

Install:
cd into directory, start your virtual environment and install the repository:
python -m venv .venv
source .venv/bin/activate
python -m pip install .Update .env:
Copy the .env.example file, rename it to .env in the root directory, and insert your seed phrase:
PHRASE="<mnemonic>"Update RPC:
In .env, update the DEV_URL with a live RPC IP and port:
If the RPC isn't correct you will likely receive a ConnectionRefusedError: [Errno 111] Connection refused error.
DEV_URL = "ws:https://127.000.000.000:9945"Run Server:
Before running your server, ensure your account has enough balance for the required minimum stake.
Use the port you have open specifically for Petals Tensor for --port, and use the port the blockchain will call for testing your peer for --tcp_port.
python -m petals_tensor.cli.run_server [model_path] --public_ip [public_ip] --port [port] --tcp_public_ip [tcp_public_ip] --tcp_port [tcp_port]Arguments:
--model_path: The HuggingFace model path.
--public_ip: The public IP of the server for other peers to connect to.
--port: The port of the server for other peers to connect to.
--tcp_public_ip: The IP for the blockchain to call.
--tcp_port: The port for the blockchain to call.

The following is the original Petals documentation. Much of this will still apply but refer to the documentation here: https://docs.hypertensor.org
Petals is a community-run system — we rely on people sharing their GPUs. You can check out available models and help serving one of them! As an example, here is how to host a part of Stable Beluga 2 on your GPU:
🐧 Linux + Anaconda. Run these commands for NVIDIA GPUs (or follow this for AMD):
conda install pytorch pytorch-cuda=11.7 -c pytorch -c nvidia
pip install git+https://github.com/bigscience-workshop/petals
python -m petals.cli.run_server petals-team/StableBeluga2🪟 Windows + WSL. Follow this guide on our Wiki.
🐋 Docker. Run our Docker image for NVIDIA GPUs (or follow this for AMD):
sudo docker run -p 31330:31330 --ipc host --gpus all --volume petals-cache:/cache --rm \
learningathome/petals:main \
python -m petals.cli.run_server --port 31330 petals-team/StableBeluga2🍏 macOS + Apple M1/M2 GPU. Install Homebrew, then run these commands:
brew install python
python3 -m pip install git+https://github.com/bigscience-workshop/petals
python3 -m petals.cli.run_server petals-team/StableBeluga2📚 Learn more (how to use multiple GPUs, start the server on boot, etc.)

🦙 Want to host Llama 2? Request access to its weights at the ♾️ Meta AI website and 🤗 Model Hub, generate an 🔑 access token, then add --token YOUR_TOKEN_HERE to the python -m petals.cli.run_server command.
🔒 Security. Hosting a server does not allow others to run custom code on your computer. Learn more here.
🏆 Thank you! Once you load and host 10+ blocks, we can show your name or link on the swarm monitor as a way to say thanks. You can specify them with --public_name YOUR_NAME.
- You load a small part of the model, then join a network of people serving the other parts. Single‑batch inference runs at up to 6 tokens/sec for Llama 2 (70B) and up to 4 tokens/sec for Falcon (180B) — enough for chatbots and interactive apps.
- You can employ any fine-tuning and sampling methods, execute custom paths through the model, or see its hidden states. You get the comforts of an API with the flexibility of PyTorch and 🤗 Transformers.
