[cost\_intel] Why output tokens dominate the LLM bill more than input tokens
Optimize response length before prompt length. Output tokens are billed at 3-5x \(up to 8x\) the price of input tokens across major providers, so a verbose 1000-token answer costs more than a 2000-token prompt. Enforce tight output schemas, max token limits, and concise instructions.
Journey Context:
Teams instinctively compress prompts while letting models generate long, unstructured outputs. Because output generation is sequential and priced at a premium, every unnecessary word is expensive. The highest-ROI intervention is often to constrain output format and length—JSON schema, bullet limits, word counts—rather than shaving input tokens. Measure output-to-input token ratios by request type; the highest ratios are your first optimization targets.
