Inference costs. The GPT-3 paper (§6.3), gives .4kWh/100 pages of output, which works out to 500 pages/dollar from eyeballing hardware cost as 5x electricity. Scaling up 1000x and you’re at $2/page, which is cheap compared to humans but no longer quite as easy to experiment with
I’m skeptical of this being a binding constraint too. $2/page is still very cheap.
