Grok 4 可以处理多步推理、数学问题和代码分析,也适合把分散的文字材料整理成有依据的判断。例如比较两种系统架构的取舍,检查实验方案是否遗漏变量,或从需求、接口说明与故障记录中找出彼此冲突的条件。提问时给出目标、约束和可接受的结果,让模型围绕具体问题展开分析。
对于结论尚不确定的任务,可以要求它分别列出支持证据、反例和仍待确认的假设。需要比较方案时,先定义评价维度,如改动范围、维护成本或失败后的恢复方式,再让它说明每项判断对应哪段材料。这样更容易发现结论是来自证据,还是依赖了额外假设。
Grok 4 具备工具使用能力。接入并启用相应工具后,可以通过检索补充信息,或利用代码执行验证计算。工具需要由当前应用提供并允许使用;单纯发送文字请求,不代表已经搜索网页、查询 X 或运行程序。审阅结果时,检查实际检索到的页面、时间和执行输出。
提供最小可复现输入,并要求给出验证步骤。计算任务保留单位和中间公式,工程问题保留关键代码、环境与日志。把执行后的错误反馈给模型,再继续调整,比一次要求完整解决所有问题更容易控制质量。
Grok 4 属于较早一代模型。xAI 官方已将其基础版本 grok-4-0709 纳入退役重定向;复现历史结果或比较模型时,应同时确认当前渠道实际返回的模型,避免把请求名称当作固定版本保证。
例如准备重构缓存模块,可以输入:
“下面是现有缓存逻辑、两次故障记录和新需求。请先指出相互冲突的条件,再比较本地缓存与 Redis 两种方案。按一致性、故障恢复和改动范围列出依据,最后给出最小验证实验。没有证据支持的结论请列为假设。材料:{代码与日志}。”
先确认问题和评价标准,再让它细化选定方案。需要实时资料时,在应用中启用检索工具并限定日期范围;需要验证性能时,实际运行基准测试,将测量结果回传,继续修正分析。

Replace <YOUR_API_KEY> with the API key from your token settings.
All requests must include Authorization: Bearer <TOKEN> header. Anthropic-formatted endpoints accept the x-api-key header instead.
Generate tokens from the Tokens page; you can scope them to specific models, groups, IPs, and rate-limits.

Compare grok-4 API pricing, supported endpoints, capabilities and access options on Modelsell.
Create an API key with access to grok-4, then use the exact model ID and a supported endpoint from the API access section. Request fields depend on the selected endpoint.
Pricing depends on the selected provider group and the model billing unit. The current input, output, request, or media prices are shown on this page before sign-up.
Start with the use cases and prompting guidance on this page, then evaluate the model with representative inputs from your project.
