Episode notes
INSIGHT

Megabyte Advantages

  • Megabyte offers several advantages: scaling to larger sequences, compute efficiency, and raw data handling.
  • These advantages come from byte-level prediction, parallelization, and a multi-scale architecture.
INSIGHT

Tokenization Drawbacks

  • Tokenization, while compressing information, introduces problems like space handling and prompt engineering issues.
  • It also poses a challenge for multimodal models by being a lossy process for images and audio.
INSIGHT

Role of Patches

  • Megabyte processes inputs as bytes, embedding them into a global model.
  • Patches group bytes together to shorten the sequence for the global model, improving efficiency.
