Grok Build has no standalone subscription — access is bundled into your xAI plan, from $30/mo SuperGrok up to $300/mo SuperGrok Heavy, with higher limits at each tier. If you'd rather pay per token, the xAI API meters grok-build-0.1 directly. Below is every plan, the rate card, and what Grok Build actually costs a working developer.
Every Grok Build plan at a glance
Grok Build comes with SuperGrok, X Premium+ and SuperGrok Heavy. The price you pay is really the price of the xAI tier; Grok Build usage scales with it.
| Plan | Price | What you get |
|---|---|---|
| SuperGrok | $30/mo | Standard Grok Build access and limits, plus full Grok. |
| X Premium+ | $40/mo | Grok Build plus X (Twitter) Premium+ perks. |
| SuperGrok Heavy | $300/mo | The highest limits for heavy parallel workloads. |
| API (pay-as-you-go) | Per token | Meter grok-build-0.1 or Grok Code Fast 1 directly. |
Note the big jump from $40 to $300 — there's no mid-tier, so if SuperGrok's limits aren't enough, the next step is a steep one. For most developers, SuperGrok at $30 covers daily use comfortably. Curious how the product itself holds up? Read our Grok Build review.
The API rate card
If you skip the subscription and use the xAI API, Grok Build bills per token. The flagship model, grok-build-0.1, runs about $0.20 per million input tokens and $1.50 per million output tokens — aggressive rates that undercut Claude Opus for comparable work.
| Model | Input / 1M | Output / 1M |
|---|---|---|
| grok-build-0.1 | $0.20 | $1.50 |
| Grok Code Fast 1 | $0.20 | $0.50 |
For high-volume agentic loops — lots of small, fast iterations — Grok Code Fast 1 is the money-saver at $0.20 in / $0.50 out. Route routine work to it and reserve grok-build-0.1 for the harder tasks, and your token bill drops sharply.
What Grok Build really costs
For a subscriber, the honest answer is often nothing extra. If you already pay $30/mo for SuperGrok, Grok Build is bundled in — the agent is free upside on a plan you have. That's the strongest value story in the category right now.
If you go the API route, cost tracks tokens. A focused coding session on grok-build-0.1 typically runs a few dollars, and heavy daily use scales from there — but the low output rate keeps it well under what the same work costs on a premium model. Budget by your workload and model mix, not a headline number.
Which Grok Build plan is worth it?
For most developers, SuperGrok at $30/mo is the sweet spot — it bundles Grok Build with the rest of Grok and its limits cover normal daily coding. Choose X Premium+ ($40) only if you also want the X perks. Reserve SuperGrok Heavy ($300) for genuine power users running heavy parallel workloads all day.
Pure API billing is best if your usage is spiky or you want to lean on Grok Code Fast for cheap loops. Whichever route you take, the trade-off is the same: you're getting low prices in exchange for a model that trails the leaders — a deal that's easy to accept for parallelizable work and harder for quality-critical builds.

Frequently Asked Questions
How much does Grok Build cost?
Grok Build access is bundled into xAI subscriptions: SuperGrok at $30/mo, X Premium+ at $40/mo, and SuperGrok Heavy at $300/mo for the highest limits. Via the API, grok-build-0.1 is about $0.20 per million input tokens and $1.50 per million output; the cheaper Grok Code Fast 1 is $0.20/$0.50.
Is Grok Build a separate subscription?
No. There's no standalone Grok Build plan — access rides your xAI subscription (SuperGrok, X Premium+ or SuperGrok Heavy), with higher usage limits at higher tiers. You can also pay per token through the xAI API instead.
What are the Grok Build API rates?
grok-build-0.1 runs roughly $0.20 per million input tokens and $1.50 per million output tokens. For high-volume agentic loops, Grok Code Fast 1 is cheaper at about $0.20 input and $0.50 output per million tokens.
Which Grok Build plan should I get?
For most developers, SuperGrok at $30/mo is the sweet spot — it includes Grok Build plus the rest of Grok. Step up to SuperGrok Heavy ($300/mo) only if you're a genuine power user running heavy parallel workloads. X Premium+ at $40 makes sense if you also want X perks.
Is Grok Build good value?
Yes, especially if you already pay for SuperGrok — the agent comes free with a plan you have. Its API rates also undercut Claude Opus. The caveat is model quality: grok-build-0.1 trails the leaders, so you're trading some capability for the low price.
