Detailed Breakdown

Energy Consumption

Grok 4 is one of the largest models ever deployed at approximately 1.7 trillion parameters, using 100x the compute of Grok 2. At ~8.0 Wh per query, it achieves 72-75% on SWE-Bench. It runs on xAI's Memphis 'Colossus' supercluster, one of the world's largest AI training facilities.

Power Source & Carbon

xAI operates the 'Colossus' supercluster in Memphis, Tennessee, powered by hundreds of thousands of GPUs. The US South grid has a carbon intensity of ~420 g CO2/kWh. xAI has faced scrutiny over the facility's energy consumption and use of diesel generators.

Water Usage

At ~14.8 mL per query, reflecting the massive GPU cluster's cooling requirements in Memphis's warm climate.

About Grok 4

Grok 4 is a 1700B-parameter text and chat model from xAI, released July 9, 2025. ~1.7T parameters, 100x compute over Grok 2, 72-75% SWE-Bench. At 8.0 Wh per query, it uses 27x the energy of a Google search. It runs on a Dense Transformer (massive scale) architecture.

These figures are estimates derived from hardware specifications and API benchmarks — xAI has not published official energy data for Grok 4. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.

Grok 4 in Context

100%
potential savings

The efficiency alternative

Gemini Nano performs the same type of task using just 0.01 Wh per query — 100% less energy than Grok 4. For a user sending 25 queries per day, switching would save 72.9 kWh per year.

800 MWh
estimated daily

At global scale

With an estimated 10M+ daily users averaging 10 queries each, Grok 4 consumes roughly 800 MWh of electricity per day — enough to power 26667 homes.

73.0 kWh
per year

Your yearly Grok 4 footprint

At 25 queries per day, your annual Grok 4 usage consumes 73.0 kWh — a meaningful fraction of household electricity. That produces 24.8 kg of CO₂.
