Detailed Breakdown

Energy Consumption

Flux 2 Pro at 32B parameters generates images at up to 4 megapixel resolution with support for up to 10 reference images. At ~5.0 Wh per image, it is more energy-intensive than Flux 1 Dev due to its larger size and higher resolution, but produces significantly better results. Klein variant (Apache 2.0) is the fastest and most efficient.

Power Source & Carbon

Available as open-source or via BFL API. Self-hosted deployments can choose their infrastructure.

Water Usage

At ~9.4 mL per image on cloud infrastructure. Zero when self-hosted on consumer hardware.

About Flux 2 Pro

Flux 2 Pro is a image generation model from Black Forest Labs, released in November 25, 2025. Leading open image model — 32B params, 4MP resolution. Each query uses 5.0 Wh of energy and produces 2.0 g of CO₂. That's 17x the energy of a Google search — reflecting the computational demands of image generation.

These figures are estimates derived from hardware specifications and API benchmarks — Black Forest Labs has not published official energy data for Flux 2 Pro. Actual consumption may vary significantly depending on batching, quantisation, and infrastructure optimisations that we cannot observe from outside.

Flux 2 Pro in Context

45.6 kWh
per year

Your yearly Flux 2 Pro footprint

At 25 queries per day, your annual Flux 2 Pro usage consumes 45.6 kWh — roughly what a fridge uses in a month. That produces 18.3 kg of CO₂.

17x
vs a text query

Image vs text: the energy gap

Generating one image with Flux 2 Pro uses 17x more energy than a text conversation with ChatGPT. The diffusion process that creates images requires many iterative passes through the model, each refining the image from noise — far more compute per output than generating text one token at a time.
