What they did and found
Researchers tested a fast-reading method with a large language model and a separate setup to read long texts in layers. They found about 22.7× speed for prefill and 4.6× for decoding at 10 million tokens, with accuracy near the baseline.
Why it matters
If AI can read very long texts faster, it could help with long reports or research projects without losing trust in results.
The idea is to group text by meaning and read whole blocks instead of every word. This keeps accuracy near full methods up to 10 million tokens.
Reading long texts faster is possible, but memory needs and accuracy vary with document length and model setup across different kinds of documents.
What remains uncertain
The study notes accuracy differences beyond tested ranges and higher memory use as context grows.
