Why token counting misleads AI agent developers

Agentic AI systems consume far more tokens than simple prompts. Experts argue the focus should shift to measuring what actually gets built.

Summarized from MIT Technology Review AI, . 30-second read.

When tackle coding tasks, they don't respond once. They plan, write code, test, debug, and iterate—a process that can burn 10 to 50 times more than a single chat exchange. This multiplier effect means traditional token-based pricing and budgeting can mislead teams building with AI agents.

The piece argues that rationing tokens to control costs backfires when using agentic systems, because it constrains the iteration and refinement that makes agents useful. A better metric tracks actual output: what ships, gets deployed, or solves real problems, rather than raw token consumption.

The insight matters for anyone building AI-powered tools, managing infrastructure costs, or evaluating AI agent performance in production.
