> If we multiply that by 30x for video (a fair assumption for models like minimax H3, which take that much longer to make video)

It takes about 7 minutes for my RTX 5090 to generate a 15 second video with MiniMax H3. At 600 watts, that's 252,000 watt-seconds, or 0.07 kilowatt-hours.

My electricity is 18 cents/kWh, so $0.0126. Just a little over a penny.

No way gpt-image-2 is as cheap as SDXL. (I dont concern about gpt-image-2's consumption either, just pointing out it's not a good comparison)

People always napkin math something low, and then every academic who formally studies it ends up with a much higher estimate.

I await OpenAI's carbon footprint field.
