Model comparisons
Head-to-head cost for 47 cross-provider pairings, each showing real monthly spend on three workload shapes rather than headline per-token rates. Caching, batch discounts and tokenizer differences are applied.
Only cross-provider pairs within a comparable price band are listed — pairings nobody would realistically weigh against each other are left out on purpose.
