Optimizing large language model (LLM) costs requires a strategic approach beyond simply shortening prompts. Developers should focus on context engineering, identifying unnecessary elements in conversation history, system prompts, and tool schemas, which constitute the majority of token usage. Measuring token consumption before and during optimization is crucial, as is understanding the significant price disparities between different models, with frontier models being orders of magnitude more expensive than smaller, task-specific ones. Controlling output length is also vital, as output tokens are considerably more costly than input tokens. AI
