Antirez: High prefill speed makes LLMs feel 10x more powerful
antirez · x · 2026-08-27
Antirez suggests that increasing prefill speed from 500 to 5000 tokens/second drastically changes user perception, making the same model feel 10x more powerful. Drawing parallels to fast compilation in C, he argues that in the agentic era, developers should avoid slow-to-compile languages like C++ to fully leverage high prefill throughput and speed up iteration cycles.
