LLM API price ranking and free tokens

Find the cheapest LLM API for each model

Updated: API prices observed 2026-10-03T23:38:24.291Z to 2026-10-24T04:29:08.131Z (UTC).

Grandet collects public prices from 1,878 sites. Each model has three columns: the official cash price, inference providers' cash prices, and API relays' credit prices. Relay prices are converted with the site's multiplier and group into a price per million tokens, with the original group name and the observation date.

Let your AI assistant look it up

Tell your assistant:

Once installed, ask Codex, Claude Code, Cursor and other apps for the lowest price or free credits, and connect the chosen API to the app.

Relay terms at a glance

倍率

Billing multiplier. In New API, credit deducted = (input + output × completion multiplier) × model multiplier × group multiplier.

分组

A set of channels within a site, with its own rate multiplier; requests go through the channels of the group used and are billed at that group's multiplier.

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.
