An experimental file compression method using an overfitted transformer and arithmetic coding to memorize and compress individual files.

A novel approach to file compression that achieves high ratios (e.g., 100MB CSV to 7MB) by training a small transformer to 'memorize a single file and predict the next byte.'

This experiment demonstrates a specialized, high-ratio file compression technique with significant B2B potential, despite its current performance limitations. The ability to compress a 100MB CSV to 7MB is compelling for industries dealing with large, repetitive datasets, such as financial logs, s...
