On prices, sources and limits

No. We only organise publicly published prices, units, billing rules and update dates. We don't take payment, guarantee anything or place orders. Every transaction still happens on the original platform.

The capture date on each page is the last manual check. Vendors don't notify third parties of price changes, so the original site always wins — especially on rows that mention a promotion.

Most of the gap isn't the model, it's the billing basis: thinking tokens included or not, long-context premium, how cache hits are counted, batch or promo pricing. The Relay calculator page shows how to normalise it.

Not by list price. Relays usually price in two parts (top-up ratio × model multiplier), and the multiplier may differ for input and output. Put both into the calculator to get a CNY cost per million tokens on the same basis.

A top-up activates a month on your own account; a ready-made account is an already-activated account handed to you; a key code/CDK is a self-service redeem code; a Team seat puts you inside someone else's workspace. Different delivery means different account ownership and support responsibility. See the Delivery page.

No. Low prices usually come from regional pricing, annual prepay, split Team seats, promo windows and leftover stock — each with its own expiry condition. We don't rank by lowest price or mark a channel as recommended.

All from the vendors' own pricing pages, each row linked. Nothing here is scraped from third parties, and no store or product is invented.

Yes — use the format at the bottom of the Delivery page. We only accept links that can be publicly checked, not private quotes that are just a contact handle.
