Token Density
"The measurement of information per token in a system prompt. High density reduces costs and increases reasoning accuracy."
Operator's Perspective
Token density is about engineering efficiency. Every word in a system prompt must earn its place. If a prompt can be shortened by 30% without changing the output behavior, the original was poorly optimized. High-density prompts are parsed faster by LLM attention heads, reducing attention drift and improving long-context recall.
Technical Application
Perform a prompt cleanup pass: replace wordy descriptions with bulleted lists, use structured JSON configurations for dynamic inputs, and leverage mathematical notation for logical rules.
Founder_Note
"Think of token density as writing code. You wouldn't write a 100-line function when a 10-line function is cleaner and faster. Treat your system instructions with the same discipline."
