网站介绍

api.x.ai 是 xAI(马斯克旗下)官方 Grok 大模型付费 API 端点,OpenAI 兼容;主营按量付费,附带有限的新用户试用额度与(已多次变更的)数据共享额度计划。

免费额度

无永久免费层。新账号通常获约 $25 促销试用额度(随促销/区域/验证状态而定,约 30 天过期且不结转)。历史上的「数据共享计划」曾每月赠 $150,但需先消费满 $5 并主动开启用 API 请求训练模型、team 级开启后不可退出;该 $150 计划据报道已于 2025 年 5 月调整/结束,需以登录 xAI Console 当下实际显示为准。

免费模型

Grok (试用额度内可调用当前 Grok API 模型,如 grok-2 / grok 系列,具体以官方目录为准)

社区口碑综述

xAI 是有明确主体的一线大厂,api.x.ai 为其官方 Grok API 端点,不存在中转站式盗 key 或跑路风险,技术口碑可。但「免费」部分高度不稳定:早期 $25/月、后续 $150/月数据共享额度均经历多次变更,社区与多家攻略站均提示 2025 年中相关免费计划已调整或结束,且数据共享以用请求训练模型为代价、team 级不可退出。网络上流传的高额免费额度多为过期信息,应以登录 Console 实际显示为准。

使用建议

适合想短期评估 Grok 能力的开发者用新用户试用额度试用;不要把它当长期免费来源。务必以登录 xAI Console 当下显示的额度与条款为准,不要轻信第三方「$150/$175 永久免费」攻略。若考虑数据共享计划换额度,须知会用你的请求训练模型且不可退出,敏感/受监管数据切勿开启。

New users receive $25 in free sign-up credits plus up to $150/month through the data sharing program for a combined total of up to $175 in the first month.

Offers a recurring $150 monthly credit in exchange for consenting to share API request metadata and outputs; teams must have at least $5 in total API spending to be eligible.
Glarity / 社区问答 · neutral
The data sharing program means xAI can use your API interactions for model training. If you handle proprietary or sensitive data, keep data sharing disabled.

yangmao.ai - Grok API Free Credits 2026: Program Ended? · negative
xAI ended its data-sharing program in May 2025, which had provided $150/month in free API credits; there is no longer a free API tier for new developers. Promotional credits expire 30 days after account creation. Do not rely on Reddit-era $150-credit posts unless the same offer appears in your xAI Console today.

In English

Summary: api.x.ai is xAI's (Elon Musk's company) official paid API endpoint for the Grok LLMs, OpenAI-compatible; primarily pay-as-you-go, with a limited new-user trial credit and a (repeatedly changed) data-sharing credit program.

Free quota: No permanent free tier. New accounts typically get ~$25 in promotional trial credit (varies by promotion/region/verification, expires in ~30 days and does not carry over). A historical 'data sharing program' once gave $150/month but required first spending $5, opting in to use your API requests for model training, and was non-revocable once enabled at team level; that $150 program is reported to have been changed/ended around May 2025 — rely on what your xAI Console actually shows now.
