Detailed Breakdown

Energy Consumption

GPT-5.4 Nano is the smallest and most efficient member of the GPT-5.4 family at ~0.3 Wh per query. Designed for edge deployment and cost-sensitive applications, it brings GPT-5.4 generation intelligence to the efficiency class of GPT-4.1 Nano.

Power Source & Carbon

Can run on edge devices and mobile hardware in addition to cloud infrastructure.

Water Usage

At ~1.1 mL per query. Near-zero when deployed on edge devices.

About GPT-5.4 Nano

GPT-5.4 Nano is a text and chat model from OpenAI, released in March 5, 2026. Smallest GPT-5.4 variant — edge and mobile deployment. Each query uses 0.30 Wh of energy and produces 0.13 g of CO₂. That's roughly comparable to a traditional Google search. It ranks in the top quartile of text and chat models for energy efficiency (#18 of 94).

These figures are estimates derived from hardware specifications and API benchmarks — OpenAI has not published official energy data for GPT-5.4 Nano. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
