This project demonstrates that MedGemma-4B-IT, combined with Unsloth, enables memory-efficient fine-tuning while maintaining strong healthcare-focused reasoning and response quality.

Highlights

  • Memory-efficient fine-tuning
  • Faster training with Unsloth
  • LoRA-based parameter-efficient adaptation
  • Lower GPU memory requirements
  • Strong medical reasoning capabilities
  • Ready for inference and deployment

This repository showcases an efficient workflow for adapting MedGemma-4B-IT using Unsloth, making healthcare-specific language models easier to fine-tune and deploy on consumer-grade hardware.


Future Work
