Authenticity checks (model consistency and dilution) are not live yet; once they are, this section will compare the relay with the official API.便宜、直接的 GPT 上游接入。在一个平台探索模型 API、查看清晰价格，为你的下一个想法连接所需的工具。

Authenticity

Model consistency

Output distribution for the same requests on this relay and on the official API · higher is better

Once authenticity checks are live, this shows the distribution distance from the official API, capability-question pass rates side by side, and usage count drift. Routes that fail are greyed out on every leaderboard, with the reason shown in red on hover.

Cache

Coding requests repeat much of their context, so the cache hit rate largely decides what you actually pay. Drag the hit rate and the costs and ranking below are reweighted with cache prices.

FAQ

How much does GPT 5.5 cost on CheapAI?

No public price yet.

How does the cache hit rate affect price?

CheapAI has not published a cache price for this route, so cache hits are billed at the input price.Measured hit rates will replace this assumption once available.

Which models does CheapAI support?

Folkbench currently lists 11: GPT 6 Astra, Claude Opus 5.5, GPT 6.1 Sol, Claude Sonnet 5, GPT 5.6 Sol, Claude Fable 5, Claude Opus 5, GPT 5.6 Terra, Kimi K3, GPT 5.5, GPT 5.6 Luna.

What does the data security level mean?

Folkbench rates relays from 0 to 4 based on public policies and verifiable evidence; CheapAI is currently level 3. The check covers leaks in responses and error messages only, and does not prove data retention or training policies.

How often is this data updated?

Availability and time to first token use a 24-hour window, and this page syncs live data every 15 minutes.
