LLM token usage slashed by 99% with RAG, TOON, and batching

A production engineering approach has significantly reduced LLM token usage and processing time for an automated candidate sourcing system. By implementing retrieval-augmented generation (RAG) with semantic routing and caching, the system now retrieves only relevant data snippets instead of full histories. The adoption of TOON (Token-Oriented Object Notation) further decreased token count by eliminating JSON's syntactic overhead. Finally, batching API calls instead of processing candidates sequentially drastically cut down on both token consumption and execution time. AI

IMPACT Demonstrates practical methods for reducing LLM operational costs and latency, crucial for scaling AI applications.

RANK_REASON Article details a specific engineering technique for optimizing LLM usage, not a new model release or frontier research.

    How I Cut LLM Token Usage by 99% — 3 Production Engineering Steps

    <p>At Idyllic Services, I was working on an automated candidate sourcing system running LLM calls at scale. One iteration consumed <strong>200,000+ tokens</strong> (costing ₹15–20 per run) and took <strong>6 minutes</strong>.</p> <p>I redesigned the pipeline architecture to cut t…
