Vantage tracks spot interruption rates. We compute the bid that minimises $-per-training-step given your checkpoint frequency.
Optimisation objective: bid × hours-until-interrupt × restart-overhead ÷ training-steps-completed.
Optimal bid: 20% of on-demand = $6.554/hr. At this bid, expected 7.2 interrupts over the 40.0-hr training run; each interrupt costs 15min checkpoint + 8min restart (=6.9% overhead). Effective $/training-step = $0.05866, vs $0.27308 on-demand → 79% savings.
