Instead of overloading one machine with multiple sub-agents competing for resources, PAIR spreads the workload and returns results to the main system, adapting in real time as household GPUs become busy or free again.

Climate Scientist Logs Energy Use of 1,138 Claude Code AI Prompts

Zeke Hausfather, a climate scientist who relies on AI for research, spent eight weeks tracking 1,138 prompts he sent to Claude Code to estimate the electricity consumed at the data centers processing them. His findings suggest that AI agents, which perform multi-step autonomous tasks, draw significantly more power than the simple chatbot queries tech companies typically cite as low-energy examples.
