About SpaceXAI: Grok Build 0.1

SpaceXAI: Grok Build 0.1 is a text generation model from xAI, listed on api14 under the model id x-ai/grok-build-0.1. It is described as a fast coding model trained specifically for agentic software engineering workflows, which places it in the category of models intended to work inside tools and loops rather than only answer one-off prompts. Its provider release date is 2026-05-20.

The model accepts text, image and file inputs, and it produces text output. It has a context window of 256,000 tokens, and its maximum output is 230,400 tokens. Because it is optimized for interactive coding, it is built for exchanges where the model reads a codebase or a task description, reasons about it, and returns code or instructions that a developer or an agent can act on directly.

Practical uses follow from those capabilities. Agentic software engineering workflows are the primary fit: reading files, planning changes, writing or editing code, and responding to follow-up instructions across a long session. The image input modality also allows screenshots, diagrams or rendered output to be passed in alongside text, which is useful when a bug or a design needs to be described visually. The large context window and large maximum output make it suitable for tasks that involve substantial source material or that require long generated results, such as multi-file changes or detailed implementation plans.

You call the model through api14's OpenAI-compatible API using the model id "x-ai/grok-build-0.1". The supported request parameters are include_reasoning, logprobs, max_tokens, reasoning, response_format, seed, structured_outputs, temperature, tool_choice, tools, top_logprobs and top_p. Tool calling and structured outputs are available, so the model can be wired into agent frameworks that expect function calls or schema-constrained JSON. The reasoning and include_reasoning parameters let you control whether reasoning content is requested, and logprobs with top_logprobs give token-level probability information when you need it.

There is no information here about pricing, rate limits or regional availability, so those should be checked on the live price table and in your account. If your task is purely text generation without coding or tool use, another text model may be a simpler fit, but for agentic coding work with text, image and file inputs, this model is designed for exactly that.

How to call the SpaceXAI: Grok Build 0.1 API

  1. Create an API key in your dashboard.
  2. Install the official openai SDK for your language.
  3. Set baseURL to https://api14.com/api/v1 and model to "x-ai/grok-build-0.1".
import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "https://api14.com/api/v1",
  apiKey: process.env.API14_API_KEY,
});

const result = await client.chat.completions.create({
  "model": "x-ai/grok-build-0.1",
  "messages": [
    {
      "role": "user",
      "content": "Explain vector databases in two sentences."
    }
  ]
});
console.log(result.choices[0].message.content);
