Details

Gemma Multimodal Fine-Tuner is a tool that supports fine-tuning Gemma models on Mac environments using multimodal data including text, images, and audio. It works natively on Apple Silicon (MPS) without an NVIDIA GPU, and provides efficient training by leveraging the LoRA technique.

Key features are as follows:

  • Multimodal training: Fine-tuning is possible not only with text but also with image (captioning, VQA) and audio data.
  • Cloud data streaming: Data can be streamed directly from GCS or BigQuery, enabling training on terabyte-scale large data without local SSD capacity limitations.
  • Real-time visualization: Loss curves, attention heatmaps, gradient signals, and more can be monitored in real time through a browser.

Unlike existing MLX-LM or Unsloth, this tool is optimized for multimodal training and cloud data streaming on Apple Silicon. This allows domain-specific ASR (Automatic Speech Recognition), vision models, and document understanding models for fields such as healthcare, law, and manufacturing to be built privately on a personal Mac.
