AI is becoming AI's biggest customer as agentic token usage jumps 14x on OpenRouter

Since February 6, 2025, AI agents have surpassed human token usage on OpenRouter, with agent usage increasing by 14 times compared to a 2.8 times increase for humans. Data indicates that nearly 70% of agent token consumption comes from inexpensive cached prompts, suggesting that actual costs are rising much more slowly than the raw figures imply. This shift signifies that AI is becoming the largest customer of AI, highlighting the growing importance of agents and indicating potential changes in operational costs and development in the field.
