Felafax -- tune LLaMa3.1 on Google Cloud TPUs for 30% lower cost and scale seamlessly!

Felafax is a framework for continued-training and fine-tuning open source LLMs using XLA runtime. We take care of neceessary runtime setup and provide a Jupyter notebook out-of-box to just get started.

• Easy to use.
• Easy to configure all aspects of training (designed for ML researchers and hackers).
• Easy to scale training from a single TPU VM with 8 cores to entire TPU Pod containing 6000 TPU cores (1000X)!

Goal

Our goal at felafax is to build infra to make it easier to run AI workloads on non-NVIDIA hardware (TPU, AWS Trainium, AMD GPU, and Intel GPU).

Currently supported models

• LLaMa-3.1 JAX. $${\color{red}New!}$$

  • Translated the model from PyTorch to JAX.
  • Implements 2-way data parallel and 2-way model parallel training.
  • The multi-GPU training works on NVIDIA GPUs and TPUs!
  • Supports full-precision training.

• LLaMa-3/3.1 PyTorch XLA.

  • Supports LoRA and full-precision training.

• Gemma2 2B, 9B, 27B on Cloud TPUs.

  • Supports fast full-precision training.

• LLaMa-3.1 405B will be available on our cloud platform at felafax.ai -- sign-up for the waitlist!

Setup

For a hosted version with a seamless workflow, please visit app.felafax.ai 🦊.

If you prefer a self-hosted training version, follow the instructions below. These steps will guide you through launching a TPU VM on your Google Cloud account and starting a Jupyter notebook. With just 3 simple steps, you'll be up and running in under 10 minutes. 🚀

1. Install gcloud command-line tool and authenticate your account (SKIP this STEP if you already have gcloud installed and have used TPUs before! 😎)

    # Download gcloud CLI
    curl https://sdk.cloud.google.com | bash
    source ~/.bashrc
   
    # Authenticate gcloud CLI
    gcloud auth login
   
    # Create a new project for now
    gcloud projects create LLaMa3-tunerX --set-as-default
   
    # Config SSH and add
    gcloud compute config-ssh --quiet
   
    # Set up default credentials
    gcloud auth application-default login
   
    # Enable Cloud TPU API access
    gcloud services enable compute.googleapis.com tpu.googleapis.com storage-component.googleapis.com aiplatform.googleapis.com
   

2. Spin up a TPU v5-8 VM 🤠.

   sh ./launch_tuner.sh
   

   Keep an eye on the terminal -- you might be asked to input SSH key password and need to put in your HuggingFace token.

3. Clone the repo and install dependencies

   git clone https://github.com/felafax/felafax.git
   cd felafax
   pip install -r requirements.txt
   

4. Open the Jupyter notebook at https://localhost:888 and start fine-tuning!
