What Grok actually costs.
Grok has the messiest pricing ladder of the major tools — multiple subscription tiers, one of the cheapest APIs around, and a "free credits" program with a catch. Here's the honest map, with real August 2026 numbers.
01 The plans
| Plan | Price | Notes |
|---|---|---|
| Free | $0 | Limited Grok access |
| SuperGrok | $30/mo ($300/yr) | Standalone power access — the main paid tier |
| X Premium+ | $40/mo | Grok bundled with X (Twitter) premium features |
| SuperGrok Heavy | $300/mo | Maximum access — for the heaviest users |
Note SuperGrok ($30) is pricier than the $20 standard tier elsewhere, and there are multiple doors in (standalone vs via X). Pick the one that matches how you actually use it — don't pay for X Premium+ if you just want Grok.
Update — August 2026: the plan names now decide which products you get, not just how many messages. Two access changes landed in the same week, and they pull in opposite directions:
| Product | Who has it (as of Aug 21, 2026) | Source |
|---|---|---|
| Build Mode | Every plan, including Free — web, iOS and Android. Was SuperGrok Heavy early beta until Aug 19. | SpaceXAI, Aug 19 |
| Grok Bot | SuperGrok Plus, SuperGrok Heavy, Cursor Pro+, Cursor Ultra, Cursor Teams (Standard and Premium). Enterprise: waitlist. No free tier. | SpaceXAI, Aug 21 |
Two honest caveats on the table above. First, SuperGrok Plus is a tier SpaceXAI now names in its own announcements but does not publish a price for on its public pages — we are not going to invent one, so check the rate card in your account before you assume where it sits. Second, agent products are the fastest-moving line item in Grok's pricing: what a plan includes changed twice in three days in August. Re-check entitlements before you upgrade for a feature.
02 Pay-per-use (the API) — genuinely cheap
Here's Grok's real edge: the API is one of the cheapest of any frontier model. Per million tokens (input / output):
| Model | Input / Output (per 1M) |
|---|---|
| Grok 4.6 (current flagship) | $2 / $6 — a fast variant costs twice that |
| Grok 4.5 | $2 / $6 |
| Grok 4.1 Fast | $0.20 / $0.50 |
| Grok 3 | $3 / $15 |
Grok 4.1 Fast is roughly 10× cheaper than most rivals' everyday models — which makes it a strong pick for high-volume, automated work where cost matters more than the absolute frontier.
The flagship line held its price twice running. Grok 4.5 launched at $2/$6 on July 8, 2026, and Grok 4.6 shipped on August 12, 2026 at exactly the same rate — unusual in a year where most labs raised the flagship tier. That is the number worth remembering about Grok: a frontier-band model priced like a mid-tier one.
03 What a prompt actually costs
- Summarize a 2-page doc (~800 in / 1,200 out): under $0.001 on Grok 4.1 Fast — a tenth of a cent.
- Analyze a long report (~2,500 in / 3,500 out): about $0.002 on 4.1 Fast.
On the cheap model, even heavy usage barely registers — which is exactly why builders eye it for volume.
04 The "free credits" trade — read this
xAI offers up to $175/month in free API credits through a data-sharing program. The catch: your API prompts and outputs can be used to train xAI's models.
05 Which is right for you?
- Just want Grok in chat: Free, or SuperGrok ($30) if you hit limits.
- Already pay for X: X Premium+ ($40) bundles it.
- Builder / high-volume: the API on Grok 4.1 Fast — cheapest in class. Decline the data-sharing tier for anything sensitive.
See how Grok stacks up against every other tool for your usage — it often wins on the pay-per-use side.
Open the AI Cost Calculator →The $5 experiment
Open an xAI console account, set a $5 cap, and run your three hardest prompts on Grok 4.1 Fast — declining the data-sharing program so your prompts stay yours. You'll see both the model quality and just how little the usage costs.

- Untangle the tiers: Free, SuperGrok $30, X Premium+ $40, Heavy $300
- Know the API is cheap — Grok 4.1 Fast at $0.20 / $0.50, flagship 4.6 at $2 / $6 per million
- Price the free-credits trade correctly: compute for training data
- Decline data-sharing for anything client or business sensitive
