AI agents in .NET can cut token costs by optimizing tool lists

This article explores methods for reducing token costs associated with AI agents in .NET applications. The author conducted experiments using llama.cpp and a Qwen2 tokenizer to measure the actual token usage of different tool lists and prompt configurations. The findings indicate significant cost reductions are possible by optimizing the tool catalog size, with a 120-tool list costing nearly 98% fewer tokens than a 15-tool list when processed by the tokenizer.

    Cutting Agent Token Costs in .NET: Tool Search, Output Gating and What the Numbers Really Say

    <p>Every few days another post tells me I can cut my agent’s token bill by 60%, 90%, 98%. I believe most of these numbers are real in the setup where they were measured. What I never know is whether they survive contact with my setup.</p><p>So I tried to build the stack myself in…
