Summary

The creator is building a notebook that fine-tunes the small Gemma4-E2B model to write in his own tweet style, using Unsloth. He runs it through a Google Colab plugin inside Devin Desktop. It shows a practical style fine-tune of a small open model on personal data.

Key points

• Small open models like Gemma4-E2B can be fine-tuned to copy a personal writing style (here, the creator's tweets).
• Unsloth is the fine-tuning library used for the training notebook.
• Training runs in a notebook through a Colab plugin, so it uses cloud GPUs instead of local hardware.
• The notebook was written inside Devin Desktop, an AI coding tool that has a Colab plugin.
