FAQ
- What is the official or public reference price for Claude sonnet 4.5?
- We take the lowest price among official pricing pages and public marketplaces (e.g. OpenRouter) as reference: openrouter, $15.00 per M output tokens, input $3.00. CNY prices are converted at the day's rate; snapshots are clickable.
- Relay sites sell Claude sonnet 4.5 far below the official price. Is that credible?
- We only do arithmetic: effective ÷ reference. Quotes below 15% are under the model's cost floor with no subsidy assumed; we label them "mathematically unsustainable" but don't speculate on causes or draw conclusions. Whether to buy is your call. Currently 7 sites are within range and 15 are below the cost floor.
- How is a relay site's effective price calculated?
- Panel list price (multiplier × $2/M) × the site's top-up rate (CNY charged per $1 of nominal credit) ÷ the day's USD/CNY rate. All three numbers are in the evidence drawer and trace to fetch snapshots.
- How can I verify a site serves the real Claude sonnet 4.5?
- "Within range" only means the price is not anomalous. Authenticity needs a protocol-consistency check with your own key for that site (our probe script or the open-source Veridrop); we don't judge for you.
- How often is data updated?
- Relay panel prices and official references are fetched automatically once a day; site reachability is probed hourly. Data date on this page: 2026-09-04.
This is an arithmetic ratio. It is not an accusation against the vendor, and a lower public source not yet indexed here may exist.
