How to Reduce Wasted LLM Tokens

A field guide to reducing bloated prompts, irrelevant context, repeated requests, malformed outputs, and runaway agent loops.

Desk note

Token reduction is only a win when accepted output holds. The target is not smaller prompts for their own sake; it is less repeated, irrelevant, or repair-heavy work.

Reduce context before ambition

Most waste starts with context discipline. Teams send whole files, long histories, and irrelevant documents because it feels safer than retrieval or task decomposition. The result is expensive calls that are harder to inspect.

  • Split tasks before sending giant context windows.
  • Use retrieval to send targeted chunks rather than every document.

On this siteThe model routing playbook

Route simple work down

Not every step needs the strongest model. Classification, extraction, formatting, low-risk planning, and validation are common candidates for cheaper routes once evals prove the quality bar holds.

  • Route by task risk, not by habit.
  • Keep a fallback path when confidence is low.

Stop paying for repeated work

Semantic caching, prompt normalization, deterministic pre-processing, and saved intermediate results can prevent teams from generating the same expensive answer again and again.

  • Start with the most repeated expensive calls.
  • Cache only where freshness and permissions are understood.

Constrain agents

Agents need explicit budgets: step limits, stop conditions, retry caps, tool budgets, and escalation rules. Otherwise a vague task can become a long trace that looks busy while it burns through model calls.

  • Require a stopping reason on each trace.
  • Alert on retry loops and long-running tasks.

Enterprise AI budgets break at the handoff to production

Express Computer interviews New Relic India's Ganesh Narasimhadevara on why AI bills keep climbing while the blended cost per million tokens has fallen over a year, from $18.40 in Q1 2025 down to $6.07 in Q1 2026.

Cisco's Splunk adds Tokenomics to track coding-agent token spend

At Splunk .conf on Sept. 15, Cisco added a Tokenomics module to Splunk Agent Observability. It attributes token spend across AI agents and across employees' use of coding agents, naming Claude Code, Codex and Cursor.

Claude Code was using 51,000 tokens before I even typed a prompt — I fixed it

Mahnoor Faisal opened a new Claude Code session, ran /context, and found 51,400 tokens already loaded. Disabling four test plugins and auto-memory got the starting context down to roughly 41,400 before any real prompt.
