Short answer: As of November 9, 2026, the cited xAI pricing information does not confirm a Grok 4-specific free trial or spell out trial terms. It lists a Free plan at $0, but does not promise a particular model there. Premium is a listed paid option at $30/month or $300/year whose plan information includes “Latest Grok models.” xAI’s release notes say Grok 4.7 powers Expert mode on grok.com; they do not establish that the Free plan includes it. (x.ai)
A free plan, a time-limited promotion, and a formal free trial are different offers. Older third-party reports described temporary Grok 4 access in 2025 and a three-day SuperGrok trial as of May 2026. Those reports do not verify that a trial is available now or explain its signup, payment, cancellation, or renewal terms.
What Grok access costs
The cited xAI subscription pricing lists these relevant individual options:
| Option | Listed price | What the published plan information establishes |
|---|---|---|
| Free | $0/month | The pricing page lists a Free plan; it does not name a specific model for this tier. |
| Premium | $30/month or $300/year | The plan information lists “Latest Grok models.” xAI release notes say Grok 4.7 powers Expert mode on grok.com. |
The cited pricing pages display prices with a dollar sign. The materials cited here do not establish applicable taxes, purchase-channel differences, or the final amount at checkout. The annual Premium price is $300 billed annually, equivalent to $25 per month when averaged over the year—not a monthly $25 plan. (x.ai) (x.ai subscription pricing)
Which should you choose? For a no-cost first look, start with Free, but don’t count on it providing Grok 4 or Grok 4.7. If you need a plan whose published information explicitly says it includes the latest Grok models, Premium is one listed option. This does not establish that Premium is the lowest-priced qualifying plan. Its price is a subscription price, not a confirmed trial renewal price; the cited published material does not provide a Grok 4 trial’s duration, eligibility, payment-method requirement, usage cap, or post-trial charge.
Is there a Grok 4 free trial?
A current, official Grok 4-specific trial is not confirmed by the published pricing information cited here. That is different from proving that no trial or promotion exists: the official pricing page lists plan prices and benefits but does not give trial terms.
Historical reports should not be mistaken for a current offer:
- Mashable reported on August 11, 2025 that xAI had announced temporary Grok 4 access for paying and non-paying users. The report called it limited-time access, not a trial with a stated term or renewal price. (Mashable)
- A third-party pricing guide reported a three-day SuperGrok trial as of May 2026, but its October 2026 update did not reconfirm the trial. It did not supply eligibility, card, cancellation, or renewal details. (TechJack Solutions)
- A third-party page advertising “free AI chat with Grok 4.1 Fast” does not establish a Grok 4 trial. Those are different model names, and that page does not state a trial duration, quota, or price. (
1min.ai)
Before relying on a trial, confirm in the offer itself: the exact model, trial length, usage limits, eligibility, whether payment details are required, cancellation deadline, and price after the trial. If those terms are not shown, treat the offer as unconfirmed rather than assuming you can test Grok 4 for free and cancel before a charge.
Consumer access is not the same as API access
A consumer subscription or temporary chat promotion does not, by itself, establish free production API credits. The xAI API quickstart instructs developers to load credits before making API requests. The cited published documentation does not clarify whether a consumer subscription includes API usage or offsets metered API charges. Check the terms for the specific subscription and API account you intend to use; do not assume a consumer trial includes API credits. (xAI API quickstart)
For production development, the current xAI developer documentation identifies grok-4.7 as an API model. It lists a 500,000-token context window, text and image input, text output, configurable reasoning, and function calling, web search, X search, and code-execution tools. These are documented features, not a guarantee that a particular application or workload will perform as required; test your own use case before deployment. (Grok 4.7 Developer Guide)
Grok 4.7 API rates and a sample budget
xAI lists these Grok 4.7 rates for prompts below the long-context threshold:
| Charge type | Price per 1 million tokens |
|---|---|
| Input | $2.00 |
| Cached input | $0.50 |
| Output | $6.00 |
The pricing entry labels the long-context tier as 200,000 tokens or more and lists rates of $4.00 per million input tokens, $1.00 per million cached input tokens, and $12.00 per million output tokens. The cited pricing information does not establish which token count determines that threshold or whether the higher rates apply to the entire request or only to tokens above the threshold. Do not assume either billing rule when estimating requests near or above the threshold; confirm it with xAI. The API pricing page also says server-side tools add invocation charges on top of token charges. The U.S. regional endpoint applies a 10% premium to token rates. (xAI API pricing)
Illustrative calculation—not a forecast: If an application makes 1,000 short-context requests, each with 2,000 input tokens and 500 output tokens, that is 2 million input tokens and 0.5 million output tokens:
- Input: 2 × $2.00 = $4.00
- Output: 0.5 × $6.00 = $3.00
- Estimated token subtotal: $7.00 at global rates
This example assumes no cached-input discount, no prompt reaching the long-context threshold, and no separately billed tools. At the U.S. regional endpoint, the same token subtotal would be $7.70 after the 10% premium. Actual API charges depend on measured input, output, cached tokens, endpoint, and tool use; check xAI’s pricing before setting a production budget. (xAI API pricing)
Bottom line
- Want to try Grok without subscribing? The Free plan is listed at $0, but the published plan information does not guarantee a specific Grok 4 model or a Grok 4 trial.
- Need access to the latest models in the consumer product? Premium is a listed option at $30/month or $300/year; the cited materials do not establish whether a lower-priced plan also qualifies, or the applicable taxes, purchase-channel differences, or final checkout amount.
- Building a production app? Estimate API costs from metered rates, long-context use, and any tool calls. The cited documentation does not clarify whether subscription usage offsets API charges, so verify that relationship rather than assuming API credits are included—or that separate payment is inevitable.
