xAI 将编程模型 Grok Build 0.1 开放 API 公测

Grok Build 0.1 on API Grok Build 0.1, our fastest coding model, is now available via the xAI API in public beta. May 29, 2026

文章要点

1xAI 发布编程模型 grok-build-0.1，经 xAI API 开放公测，即驱动 Grok Build 的同一模型
2模型针对智能体编程任务训练，覆盖 Web 开发、调试并支持 MCP，服务速度超 100 tokens/秒
3定价为输入 $1/m tokens、输出 $2/m tokens，官方称也适合通用智能体与工具调用场景
4官方建议在 Grok Build、Cursor、OpenCode 等环境中使用，已上线 OpenRouter 与 Vercel AI Gateway

决策要点

xAI 以输入 $1/m tokens、输出 $2/m tokens 的定价放出高速编程模型，把智能体编程的使用成本压到更低水位。

影响：经 API 接入编程工具的企业多了一个高速低价的模型选项；通用智能体与工具调用场景也能用该模型控制成本，模型选型与 API 预算可据此重新比价。
参考：可考虑先算出当前编程场景的月均 token 用量，按 $1/m tokens 输入、$2/m tokens 输出估算账单变化；值得在 Cursor 或 OpenCode 里用真实任务对比速度与产出。
依据：定价、100+ tokens/秒的速度与适用场景均为 xAI 官方口径，模型处于公测阶段，暂无独立评测。

正文

Our latest coding model, grok-build-0.1, is now available via the xAI API in public beta.

grok-build-0.1 is a coding model specifically trained for agentic coding tasks, including web development, debugging, and MCP support. It's the same model that powers Grok Build.

The model is served at a blazing-fast 100+ tokens/second and is priced at $1/m tokens in and $2/m tokens out. Outside of coding, it’s also a speedy, economical option for general-purpose agentic and tool calling use cases.

bash

grok-build-0.1 performs best in agentic harness like Grok Build, Cursor, Hermes Agent, OpenClaw, Kilo Code, or OpenCode. It’s also available via OpenRouter and Vercel AI Gateway.
