Cheapest for a need

The cheapest models with structured JSON output

A capability probe on this deployment saw its JSON output hold, or the upstream's catalog declares response_format or structured outputs and no probe has seen it fail.

Ranked by what a typical message costs at the price you are billed: about 500 tokens sent and 500 written.

Every price here is the upstream's published price plus 10%, the same for every account.

What this list does not say

Price is the only thing it ranks. Nothing here scores how well a world does a task, so the cheapest is not a claim about the best. Try two in chat before you build on one; chat needs no key. A world with no published price is never listed here.
