Byte Latent Transformer (BLT) Model Description BLT (Byte Latent Transformer) is a tokenizer free transformer architecture that operates directly on raw byte sequences. Instead of processing text token by token, BLT dynamically groups bytes into entropy based patches , enabling more efficient and scalable processing for byte level tasks. Key components: Local Encoder → Latent Transformer → Local Decoder architecture. Entropy based patcher (BltPatcher) : scans byte streams and creates patches when entropy thresholds are met. Hash n gram embeddings : maintain contextual information over neighboring bytes. BLT achieves competitive performance compared to traditional token based transformers, supporting multilingual, noisy, or mixed script input.
