Find the cheapest LLM API for each model
Grandet collects public prices from 1,864 sites. Each model has three columns: the official cash price, inference providers' cash prices, and API relays' (中转站) credit prices. Relay prices are converted with the site's multiplier (倍率) and group (分组) into a price per million tokens, with the original group name and the observation date.

1:1
Two uses: topping up 1 yuan gives US$1 of credit; or a rate multiplier of 1, billed at the official price.
官转
The site claims "forwarding through official channels": mostly forwarding the official API, but some sites also call a Max subscription account pool or a cloud channel an official relay.
逆向、反代
Not using the official API; it emulates the private interfaces of the web app, subscription accounts or IDE clients and turns them into an API.
号池
Supplying calls by pooling a batch of accounts (sometimes API keys) and calling them in rotation; mostly subscription accounts.
拼车
Several people share one subscription account’s allowance and split the cost.
公益站、签到
A relay site or group that the site owner opens for free or at a very low price; credit is mostly claimed through sign-up, daily check-in or redemption codes, is often limited, and may change at any time.
