Why the payback is realistic

On Vast.ai, cards are rented for neural networks — inference and training, not round-the-clock mining. The load is gentler, cards run cooler and last longer, and demand for AI compute is higher — so profitability is higher and payback is usually six months to a year. This is open data: you can check rates and utilization on vast.ai and calculate it by hand.

Basis: 730 h/month at the set utilization. Rates are indicative — check current ones on vast.ai.
