我们测了什么What we tested

核对 Step Plan 当前官方接入链路、Step 5 Preview 模型规格、双协议 Base URL 与限时免费体验活动口径;在没有登录态 Step Plan 权益和 API Key 的前提下,不把真实额度到账和模型生成写成已实测。

  1. 打开 StepFun 官方 Step Plan 页面,确认 Step Plan 为订阅制服务并覆盖旗舰模型。
  2. 打开官方 Step Plan 快速开始,核对 OpenAI 兼容 Base URL、Anthropic 兼容 Base URL、API Key 前置条件和推荐验证模型 step-5-preview。
  3. 打开官方 Step 5 Preview 模型页,核对 1M tokens 上下文、1M 最大输入和 64k 最大输出。
  4. 交叉核对 2026-09-20 至 2026-09-22 的当前活动信息,确认登录 15 天、首次 API 调用再 15 天、邀请奖励可将总体验期叠加至最高 75 天的活动口径。
  5. 当前测试环境没有登录后的 StepFun Step Plan 权益和可用 API Key,因此没有实际验证免费体验天数到账、具体体验档位、Credit 余额或一次真实模型响应。

测试结果Result

官方产品与接入预检通过:Step Plan、旗舰模型覆盖、step-5-preview、1M 上下文以及两套兼容接口均可由官方页面确认。最高 75 天活动口径有多处当周信息一致,但公开抓取无法展开官方登录态邀请规则,因此保留 medium confidence,并要求用户以账户活动页的实际权益和到期时间为准。

未验证 / 限制:Not verified / limits 未使用登录态 StepFun 账号和真实 Step API Key,未验证 15/30/75 天权益在账户中的实际到账、邀请计数、免费体验具体套餐档位、Credit 月池数值、并发限制和真实生成响应。公开来源对免费体验档位存在 Flash Mini / Flash Plus 冲突,因此 FreeLLM 不写死 ¥99 或 1600M Credits。
