Detailed Breakdown

Energy Consumption

o1-mini is a smaller reasoning model optimised for STEM tasks like maths and coding. At ~3 Wh per query, it uses roughly 80% less energy than the full o1 model while retaining strong reasoning capabilities for focused domains.

Power Source & Carbon

Runs on Microsoft Azure infrastructure. Its smaller size allows more efficient GPU utilisation than the full o1 model.

Water Usage

At ~12 mL per query, o1-mini uses significantly less water than o1 but still more than standard chat models due to reasoning overhead.

About o1-mini

o1-mini is a text and chat model from OpenAI, released in September 12, 2024. Smaller, faster reasoning model optimised for STEM tasks. Each query uses 3.0 Wh of energy and produces 1.3 g of CO₂. That's 10x the energy of a Google search — reflecting the computational demands of text and chat.

These figures are estimates derived from hardware specifications and API benchmarks — OpenAI has not published official energy data for o1-mini. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.
