How much does Grok Build 0.1 cost?

Billing is usage-based: $1 per million input tokens and $2 per million output tokens. There is no monthly minimum. You pay only for the tokens you actually use.

How do I access Grok Build 0.1 from inside Iran?

Create a Hormouz account, generate an API key and point your client at Hormouz. Access to Grok Build 0.1 is served from inside Iran, so you do not need a foreign credit card, a VPN or any sanction-circumvention tooling.

Is Grok Build 0.1 compatible with the OpenAI SDK?

Yes. Hormouz exposes an OpenAI-compatible chat-completions API. Change the base URL to Hormouz and drop in your Hormouz key, and existing OpenAI SDK code runs unchanged.

What context window does Grok Build 0.1 support?

Grok Build 0.1 supports a context window of up to 256K tokens, which is enough for long documents and extended conversations in a single request.

What is Grok Build 0.1 designed for?

It is a coding-focused model built for agentic software engineering. Interactive coding agents, tool use and multi-step development. It powers the Grok Build CLI and handles long-horizon coding thanks to its 256K context and uncapped output.

Is Grok Build 0.1 production-ready?

It is an early-access model, so it is best treated as a preview. It is well suited for experimenting with coding agents, but you should validate results before relying on it for critical production workflows.

SpaceXAI: Grok Build 0.1: AI model

Grok Build 0.1 is xAI's fast coding model for agentic software engineering, with a 256K context window and no output cap. Served from inside Iran through Hormouz.

Thinking levels: Always thinks

Grok Build 0.1 is a fast coding model from xAI trained specifically for agentic software-engineering workflows. It is optimized for interactive coding agents, tool use and multi-step development tasks, and it powers xAI's Grok Build CLI.

It accepts text and image input, returns text, and offers a 256K-token context window with no fixed output limit. A good fit for long-horizon coding and automation where the agent works across many files and steps. Reasoning and tool calling are supported, which is essential for coding agents that plan, edit and verify.

On Hormouz, Grok Build 0.1 is served behind an OpenAI-compatible API and reachable from inside Iran without a foreign credit card. It is an early-access model, so treat it as a preview for agentic coding rather than a fully stabilized release. Pricing is $1.00 per million input tokens and $2.00 per million output tokens.
