怎么选How to choose

先判断它是否真的适合你的使用方式Decide whether the offer actually fits your workload

选 API 时不要只看“免费”两个字。真正影响能否接入的是免费机制、接口兼容性、地区、账号门槛和限流。Do not choose an API on the word “free” alone. The practical decision is driven by the free mechanism, API compatibility, region, account requirements and rate limits.

避免误判Avoid this mistake:最常见的误判是把“注册送额度”“某个模型当前 ¥0”“第三方聚合器免费池”都写成同一种永久免费。FreeLLM 会把这些路径分开标注。A common mistake is treating signup credits, a currently ¥0 model and a third-party free pool as the same kind of permanent free access. FreeLLM labels these mechanisms separately.
FreeLLM 核验方法How FreeLLM verifies

我们优先保留可回到官方来源的事实We keep claims traceable to official sources

详情页尽量把免费方式、额度、有效期、地区、账号要求和官方入口拆开记录;没有证据的结论保持“待核验”,不会为了凑完整而猜测。Detail pages separate the free mechanism, quota, validity, region, account requirements and official source. Claims without evidence remain unverified rather than being guessed.

如果平台规则发生变化,以提供商当前官方页面为准;FreeLLM 的“最后核验”用于告诉你本站什么时候重新检查过这条记录。When provider terms change, the provider's current official page is authoritative. FreeLLM's “last checked” field tells you when we most recently re-verified the record.

「同渠道实测」是我们用该平台账号直接调用得到的数字;「仅同款模型参考」只说明同一模型在别的平台的能力得分,不代表本资源的速度和成功率。Same-route numbers come from calling that platform directly; reference rows only show the same model’s capability score elsewhere.
