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

Insight summary

• •On February 6, 2026, AI agents surpassed humans in token consumption for the first time according to OpenRouter analyst Peter Walker.
• •Agentic token usage has increased 14 times since that date, while human token usage grew 2.8 times.
• •AI agents increasingly operate autonomously for longer durations, initiating multiple additional AI processes.
• •Approximately 70% of agent token usage is from cached prompts, which have lower billing rates, moderating cost increases.
• •OpenRouter primarily uses open-weight AI models, which are less token-efficient compared to models from OpenAI or Anthropic.
• •The trend of increasing token usage by AI agents is likely similar across major AI model providers.
• •Token inflation began with reasoning models that require longer processing times before responding.
