Grok Build 0.1

by xAI

Grok Build 0.1 is xAI's coding model released in May 2026, trained to act as an autonomous software engineering agent rather than a passive code-completion helper. It powers xAI's Grok Build CLI and is built for refactoring large codebases, multi-step development workflows, invoking tools, generating structured output, and running in loops until tasks complete. The model accepts text and image input across a 256k token context window, with function calling, structured outputs, and always-on reasoning that thinks through problems before responding. Unlike general-purpose chat models, it is optimized for interactive coding agents and long-horizon development tasks where an autonomous system must make decisions and drive progress across multiple tool invocations. Served at fast inference speeds and available in public beta through the xAI API, Grok Build 0.1 is designed to embed agentic coding directly into developer workflows for high-throughput, autonomous software engineering.

Data handling per route

Each route hosting Grok Build 0.1 has its own privacy posture, residency, and no-KYC terms. Postures are maintained by qynio with a last-verification timestamp.

Get started

Call Grok Build 0.1 through the qynio gateway with one API key. Let your coding agent set it up, or call it directly β€” qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.

Or call it directly

import OpenAI from "openai";
const client = new OpenAI({
apiKey: process.env.QYN_API_KEY,
baseURL: "https://api.qyn.io/v3/compat",
});
const completion = await client.chat.completions.create({
model: "xai/grok-build-0.1",
messages: [{ role: "user", content: "Hello" }],
});
console.log(completion.choices[0].message.content);
