Exploring Byte Level Transformers.
Last December, Meta AI released paper describing their Byte Latent Transformer (BLT) and today (13 May 2025), they released the weights to Hugging Face. Let’s break down the paper and explore what makes BLT a special model. What is BLT? Let’s break down the name: • Byte: This signifies that the architecture operates directly on raw byte data • Latent: This refers to the way BLT processes the byte data. Instead of processing every individual byte in the main computation layer (which would be prohibitively costly) • Transformer: This indicates that BLT is an LLM architecture based on the Transformer model ...
