Run large language models at home, BitTorrent-style.
Fine-tuning and inference up to 10x faster than offloading
Generate text with distributed Llama 3.1 (up to 405B), Mixtral (8x22B), Falcon (40B+) or BLOOM (176B) 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 = "meta-llama/Meta-Llama-3.1-405B-Instruct"
# 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...
🚀 Try now in Colab
🦙 Want to run Llama? Request access to its weights, then run huggingface-cli login in the terminal before loading the model. Or just try it in our chatbot app.
🔏 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.

Connect your GPU and increase Petals capacity
Petals is a community-run system — we rely on people sharing their GPUs. You can help serving one of the available models or host a new model from 🤗 Model Hub!
As an example, here is how to host a part of Llama 3.1 (405B) Instruct on your GPU:
🦙 Want to host Llama? Request access to its weights, then run huggingface-cli login in the terminal before loading the model.
🐧 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 meta-llama/Meta-Llama-3.1-405B-Instruct
🪟 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 meta-llama/Meta-Llama-3.1-405B-Instruct
🍏 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 meta-llama/Meta-Llama-3.1-405B-Instruct

🔒 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.
How does it work?
- 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.
