Is Grok Free? Free Tier, SuperGrok, X Premium, Build, and API Costs

Short answer: yes. SpaceXAI's plan pricing lists a Free consumer route at $0 per month, and the Grok overview says Grok is free to start on the web, iOS, and Android. That is a genuine way to test Grok, but it is not a promise of unlimited use, every paid tier, Grok Build capacity, or free developer API calls.

The free allowance is intentionally not reduced to a message count here. SpaceXAI describes Free as available within generous limits but does not publish a stable numeric cap for chat, search, voice, images, video, or frontier-model access. Your signed-in account is the safer source for the active limit and reset behavior than an old X post or a screenshot from another region. For the current purchase-route table, use Grok Pricing.

What you can realistically test for free

The safest confirmed free test covers ordinary chat, real-time web and X search, voice, and connectors. That is enough to judge whether Grok's answer style works for you, whether its live-search citations help with current questions, and whether the web or mobile experience fits your routine. Keep the trial small enough that a changing cap does not become part of a production promise.

A useful evaluation has three parts. First, ask several everyday questions that do not need live data. Second, run a current-information task where you can inspect the cited sources. Third, try voice or one connector that matters to you if it is available in your account. If image, video, file, or Grok 4.6 access also appears, treat it as an account-level capability to test, not proof that every Free user receives a fixed allowance.

Free remains the right route while occasional limits are acceptable and you are still deciding whether the product is a fit. The upgrade signal is repeated interruption: you regularly hit the cap, need a paid-only model or mode, or want to use compute-heavy creation and coding features as a dependable workflow.

How paid SuperGrok usage works

The current plan page exposes a consumer ladder that includes SuperGrok Lite, SuperGrok, SuperGrok Plus, and SuperGrok Heavy. It publishes SuperGrok at $30 per month and SuperGrok Plus at $100 per month. SuperGrok adds higher limits and access to the frontier Grok 4.6 model; Plus adds significantly higher usage, 1080p video creation, faster replies, and priority access. The same page does not publish a fixed account quota or headline price for Lite or Heavy, so check the signed-in checkout rather than inferring one.

Paid does not mean unlimited. The consumer FAQ says a paid Grok plan receives one shared weekly usage pool that can be spent across products such as Chat, Imagine, Voice, and Build. Different actions consume different amounts because a short chat costs less compute than high-quality video or a long coding task. The Usage screen shows the percentage consumed, product breakdown, and the account's reset time.

When the included weekly pool is exhausted, paid features pause until reset, but separate Free-tier Chat and Voice limits remain. A higher subscription tier provides a larger allowance. Standard SuperGrok is therefore the practical benchmark for recurring personal use, while Plus is the upgrade route when the published Plus benefits and substantially higher capacity matter often enough to justify the price difference.

Extra Usage Credits are the short-spike option. SpaceXAI says paid users can buy them on the web from $5, they are consumed after the included weekly pool, and they expire one year after purchase unless another term is shown. Auto Top Up can add credits under a user-set monthly cap. Because top-ups use standard rates and cost more per action than included plan usage, an occasional top-up can be sensible; repeated top-ups are a signal to compare a higher tier.

X Premium and Business are different entitlements

Grok access through X is a separate purchase route. X Premium documentation says Premium raises Grok limits and Premium+ raises them further, with prices and feature availability that can vary by platform and location. SpaceXAI's consumer FAQ says the relevant X account must be linked to the Grok account for its subscription status to grant the applicable benefit.

Do not assume that X Basic, Premium, Premium+, and standalone SuperGrok tiers are interchangeable plan names with identical limits. X manages X Premium billing and refunds; SpaceXAI manages subscriptions bought through grok.com or its apps. A linked X benefit is an entitlement route, not an xAI API credit balance.

Grok Business is another distinct lane and should not be confused with X Premium Business. The SpaceXAI Business page lists self-serve Business at $30 per user per month, while Enterprise is sales-led. A team workspace adds organization billing, seat management, administration, sharing, and security controls. Business and Enterprise support Grok 4.6 and Grok Build, but they remain licensed workspace routes rather than free consumer access or API billing.

Grok Build and launch promotions

Grok Build is a separate coding-agent surface rather than another name for the consumer chat plan. The current Build documentation identifies Grok 4.6 as the model powering Build, opens browser authentication on first launch, and supports an xAI API key for non-browser use. Browser sign-in follows the account's live entitlement; using an API key moves the work onto the separately billed API route.

The original Grok Build launch described access for SuperGrok and X Premium+ subscribers. The later Grok 4.6 release advertised twice the included Build and Cursor usage for the first week. The earlier Grok 4.5 launch also offered free usage for a limited time. Those are historical launch promotions, not evidence of a permanent free Build quota or a transferable API credit.

Before relying on Build or a partner offer, verify the eligible account, current model, region, allowance, billing method, and promotion expiry in the live product. Subscription access in Build or Cursor remains different from funding requests made with an xAI API key.

The xAI API needs its own budget

A shared login does not mean shared billing. The API accounts FAQ says a Grok account and xAI API account can use the same identity, but their billing is separate. A Free, SuperGrok, SuperGrok Plus, X-linked, Business, consumer Extra Usage Credits, or launch-promotion entitlement should not be treated as payment for API-key requests.

For Grok 4.6 prompts below 200,000 tokens, SpaceXAI API pricing lists $2 input, $0.50 cached input, and $6 output per 1 million tokens. Once the prompt reaches 200,000 tokens, the long-context rates are $4 input, $1 cached input, and $12 output per 1 million tokens, and those rates apply to all tokens in the request. The Grok 4.6 model page lists a 500,000-token context window.

Those base token rates do not include every possible charge. Requests using SpaceXAI server-side tools pay token costs plus applicable tool-invocation charges. Priority Processing is billed at twice the standard token rates, and the Grok 4.6 release describes a fast variant at twice the base price. Check the official API pricing page for the active model, tool, media, storage, and processing rates before estimating production spend.

Prepaid API credits are the normal starting route, while approved teams can use invoiced billing. Reserve a separate API budget and set spending controls in the xAI Console whenever you integrate Grok into an app, call it from an automation, or run Grok Build with an API key.

A practical upgrade decision

The durable answer is simple: start Free to test the consumer experience, use SuperGrok as the paid personal benchmark, move to Plus or another live tier only for a demonstrated capacity or feature need, use Extra Usage Credits for occasional overflow, use Business or Enterprise for licensed team work, and fund the API separately. Treat X-linked access, Build authentication, and every launch promotion as distinct entitlements with their own terms.
