It is free to use, and the catch is the advertising. Model calls are paid for with ad revenue instead of a subscription: someone watches a rewarded ad, the ad network pays for that view, and that payment funds the calls the resulting credits are spent on. There is no paid tier, and prompts are not sold. The full picture is on the about page.
Two reasons, both practical. A balance stored only in a browser vanishes the moment site data is cleared, and people lost credits they had earned. And ad networks confirm a completed view by calling our server with a per-user identifier; if that identifier changes on every visit, the credit has nowhere to land. Signing in is free and takes one click with Google, or a code sent to your email.
Nothing is lost. Sign in again and the console issues a new key on the same account, with the same balance. If you think a key has leaked, revoke it from the console — the balance is unaffected.
Credits do not expire on a timer. There is a ceiling on how large a balance can grow, so credits stop accumulating past that point rather than piling up indefinitely. The daily allowance and the per-ad grant both reset each day.
Yes, a few per account — useful for separating projects. All keys on an account draw from the same balance. Creating keys in bulk to work around the daily cap is the one thing that would end the free service for everyone, so it is refused.
No. Requests are forwarded to the model provider and the reply comes straight back. What is recorded is usage — how many tokens a call consumed — because that is what the balance is deducted against. The model provider has its own data policy, which is outside our control. Details are in the privacy policy.
Not advisable. This is a free beta with no uptime promise and no support commitment. It is built for trying things out, prototyping, and side projects. If something depends on being available at 3am, buy an API key from a provider who will answer the phone.
The current list is on the models page, and the console shows what your key can call right now. The list can change: models get added, and a model can disappear when the upstream provider retires it.
Almost always a max_tokens value set too low. These models produce reasoning before the visible answer, and if the budget runs out during that stage the visible part never gets written. Raise it and try again.
Watch another ad, up to the daily cap. Past that, the balance refills with the daily allowance tomorrow. There is no way to buy credits — that is the point of the model.
No. Credits are non-transferable and cannot be cashed out. Sharing a key so several people can spend one balance is also not allowed: a key seen in use from several places at once gets disabled.
The ad networks do, not us. We do not pick individual ads and do not see who you are to an advertiser. What those networks store in your browser is covered in the privacy policy.

使用免费，代价是广告。模型调用的成本由广告收入承担，而非订阅费用：用户完整观看一条激励广告，广告平台就该次观看付费，这笔收入用于支付相应额度所对应的调用。本服务没有付费档位，也不出售用户内容。完整说明见关于本站。
两个现实原因。其一，仅保存于浏览器的余额会在清除站点数据时消失，用户已获得的额度将无法找回。其二，广告平台在确认观看完成后，会通过服务器通知回传一个用户标识；若该标识每次访问都变化，额度将无处发放。登录本身免费，可使用 Google 一键登录，或通过邮箱验证码登录。
余额不会丢失。重新登录后，控制台会在同一账号下发放新密钥，余额保持不变。若怀疑某把密钥已泄露，可在控制台将其停用，不影响余额。
额度不设过期时间。余额存在上限，达到上限后将不再继续累积。每日基础额度与单次广告发放量均按日重置。
可以，单个账号可创建数把，便于区分不同项目。同一账号下的所有密钥共用同一份余额。批量创建密钥以绕开每日上限的行为会被拒绝——这类行为是唯一可能导致免费服务对所有人终止的因素。
不会。请求转发给模型服务商后，回复原样返回。本服务仅记录每次调用消耗的 token 数，用于扣减余额。模型服务商自身的数据保留政策不在本服务控制范围内。详见隐私政策。
不建议。本服务为免费公测版本，不承诺可用性，也不提供支持保障，适用于试验、原型开发与个人项目。若您的业务需要稳定可用的服务，请向可提供服务保障的服务商购买接口。
当前列表见模型页面，控制台也会显示您的密钥当前可调用的模型。该列表可能调整：既可能新增模型，也可能因上游服务商下线而移除。
绝大多数情况是 max_tokens 设置过低。这类模型会先进行推理再输出可见内容，若额度在推理阶段耗尽，可见部分便无法生成。调高该值后重试即可。
可继续观看广告，直至达到当日上限。超出后，次日会重新发放基础额度。本服务不支持购买额度，这正是该模式的设计前提。
不可以。额度不可转让，也不可兑换为现金。共享密钥以供多人使用同一份余额同样不被允许：同一密钥在多处同时使用将被停用。
由广告平台决定，本服务不参与挑选具体广告，也无法获知您在广告主处的身份信息。广告平台在您浏览器中存储的内容，详见隐私政策。
