Third-party resale listings

Captured 2026-11-06 from the reseller marketplace subrouter.ai's public pricing list. These are third-party resale prices, not OpenAI's official price. Many resellers use shared/subscription access or reverse-engineered integrations — availability and quality are not verified by this site. Prices are USD per 1M tokens. Reseller names are the marketplace's own listing IDs, not company names — none of them is OpenAI or any other model developer.

1 reseller passed our sanity checks against OpenAI's official price; cheapest trusted price $4.50/1M blended.
