#QLoRA

Explore a methodology to enhance the performance of LLaMa3-8B in multiple non-English languages through advanced fine-tuning techniques and Retrieval-Augmented Generation (RAG). This guide details the step-by-step process, from dataset translation to the use of QLoRA and PEFT for efficient language model tuning. It covers a variety of foundation models, including LLaMa3 and Mistral, providing broad compatibility. Notably cost-effective, the project can be executed using free GPU resources like Google Colab. Discover the integration of various translation paradigms and implementation of DPO for improved model responses, suitable for developers enhancing multilingual chat platforms.

LLamaTuner is a sophisticated toolkit providing efficient and flexible solutions for fine-tuning large language models such as Llama3, Phi3, and Mistral on different GPU setups. It supports both single and multi-node configurations by using features like FlashAttention and Triton kernels to enhance training throughput. The toolkit's compatibility with DeepSpeed enables the use of ZeRO optimization techniques for efficient training. LLamaTuner also offers broad support for various models, datasets, and training methods, making it versatile for open-source and customized data formats. It is well-suited for continuous pre-training, instruction fine-tuning, and chat interactions.

The project fine-tunes the Falcon-7B language model with QLoRA on a specialized mental health dataset, derived from FAQs and healthcare blogs, ensuring anonymized, realistic patient-doctor dialogues. Utilizing sharded models, tuning is efficient on both Nvidia A100 and T4 GPUs, achieving a 0.031 training loss after 320 steps. This refined model enhances chatbot support for mental health, providing non-judgmental assistance as a complement to professional services. Available for further exploration with Gradio, this work integrates AI breakthroughs into mental health, fostering greater empathy and understanding.
