From 4K to a Million Tokens: How RoPE Scaling, YaRN, and Ring Attention Stretch the Context Window

A model trained on 4,096 tokens can be coaxed into reading a quarter-million without retraining from scratch. The trick is not bigger attention; it is lying to the model about position, and splitting the sequence across a ring of GPUs.

The Wavelength Problem: How One Number Decides a Model's Context Length

Llama 2 and Llama 3 share an attention implementation almost line for line. One constant differs: the RoPE base went from 10,000 to 500,000. That number sets the entire wavelength spectrum of the model's position signal, and it h…
