Q Laura: Fine-tuning Large Language Models with Less Computation Power

Democratizing Language Model Fine-tuning with Q Laura

Introduction

  • Q Laura enables fine-tuning of large language models with less computation power
  • Q Laura creates new weight matrices while freezing pre-trained weights
  • Results in a smaller file size after fine-tuning without compromising performance
  • Q Laura allows training large models on a single GPU with 48GB memory

Q Laura vs. Traditional Fine-tuning

  • Traditional fine-tuning involves fine-tuning the entire set of weights
  • Q Laura creates new update matrices while freezing pre-trained weights
  • Pre-trained weights' output activations are augmented by the new update matrices
  • Results in a smaller file size after fine-tuning without compromising performance

Benefits of Q Laura

  • Train a 65 billion parameter model on just a single GPU with 48GB memory
  • Preserve full 16-bit fine-tuning performance
  • Reaches 99% performance level of Charge GPT with 24 hours of fine-tuning
  • Exciting innovation for democratizing large language model fine-tuning

Training with Transformers and Bits and Bytes

  • Use Transformers and Bits and Bytes libraries for training
  • Install required libraries: Transformers, Bits and Bytes, Pfift, and Datasets
  • Load existing model using AutoTokenizer and AutoModel for causal LM
  • Specify Bits and Bytes configuration for quantization

Preparing the Model for Training

  • Prepare the model for training using 'prepare_model_for_kbit_training'
  • Enable gradient checkpointing for the model
  • Define Lora configuration for fine-tuning
  • Specify the rank factor, target module, and task for the model

Training the Model

  • Load the training dataset and instantiate the Transformer trainer class
  • Specify training arguments and output directory
  • Train the model using the instantiated trainer
  • Monitor training progress and loss values

Using the Fine-Tuned Model

  • Save the fine-tuned model locally
  • Load the model using the loader configuration
  • Combine the base model with the Lora configuration
  • Use the model for inference and generation

Conclusion

  • Q Laura revolutionizes fine-tuning of large language models
  • Democratizes the process with reduced computation requirements
  • Explore Q Laura models on Hugging Face Model Hub
  • Try fine-tuning your own models using the provided Google Colab notebook
