Frequently asked questions
How accurate is this?+
It's a rough order-of-magnitude estimate. Real energy depends on model size, hardware, batching and datacenter efficiency.
Where do the defaults come from?+
Published estimates for inference energy per token and average grid carbon intensity. Adjust them to your own figures.
