The author shares the 7 changes that make running the Hermes Agent up to 95% cheaper. Key insight: you pay for what the model reads, not just what it writes — system prompt, conversation history, memory files and per-tool instructions ride along with every message, so a one-line prompt can burn thousands of tokens before any work happens (his own first message consumed 18,900 tokens, 7% of a 272K context window).
- A free audit plugin took his overhead from 40,000 to 19,200 tokens without switching models;
- A full step-by-step walkthrough is on YouTube with the Token Optimizer dashboard on screen.
Useful for anyone running agents daily who wants to shrink their bill.
