# Agent sandbox prices: 4 vCPU / 8 GB 23 providers: one busy 1-hour session at 4 vCPU / 8 GB costs ≥ $0.0324 (Lizard) to ≥ $0.682 (Vercel Sandbox). 1 h busy: all CPU billed. 1 h at 10% CPU: lower only where idle CPU isn't billed. Fleet month: 50 × 8 h × 22 days, busy, plus any plan minimum. Fixed sizes use the smallest size that fits. "≥" means a billing term is not published.
