The short answer
xAI lists its Free plan at $0/month with limited AI use, including limited Chat and agent requests. Its public pricing information does not give a specific number of Free messages or a fixed Free reset time. The Grok FAQ says Free Chat and Voice limits are separate from the weekly usage limit for paid features and reset on their own schedule; that statement does not specify a universal Free quota or reset interval. Checked November 9, 2026. [1][2]
Wubshet Tsegaye of Nexoda Tech reported seeing a wait notice after about 10 messages during a period he estimated at roughly two hours on grok.com. That is a personal observation—not a quota xAI promises, a controlled measurement, or a reliable reset rule for your account. [6]
Budget takeaway: Don’t plan around “10 messages every two hours.” Check your own account’s notice. If you’re building a product, consumer Grok Free access does not establish developer API access, pricing, or rate limits.
How to check your current limit
Use the Grok surface where you’re working and follow any limit or refresh notice shown in your account. The official material reviewed here does not establish a Free-user navigation path to a quota counter or confirm that limits and refresh timing are identical across grok.com, the mobile app, and X. Do not treat paid-plan dashboard instructions as instructions for Free users. [2]
If the limit matters for a deadline, check before starting a long session. Follow-up questions, source requests, and revisions all take additional messages; this is a planning consideration, not evidence of a specific cap.
If Free is not enough: The X Subscription prices
For new self-serve customers, xAI lists these The X Subscription individual tiers at the following monthly prices in USD. The figures below are monthly list prices, not annual-plan rates. Existing SuperGrok, Cursor, and X Premium plans continue unless the subscriber changes or cancels them, so compare the plan actually offered to your account rather than assuming similarly named plans are interchangeable. [1][3]
| The X Subscription plan | Listed monthly price (USD) | Usage comparison shown by xAI |
|---|---|---|
| Free | $0 | Limited |
| Plus | $8 | Base |
| Premium | $30 | 4× Plus |
| Super | $100 | 15× Plus |
| Ultra | $200 | 50× Plus |
These usage comparisons describe relative included usage, not a promised number of messages. Applicable taxes or fees may be added at checkout, and prices can change; check the current plan and checkout total before paying. [1][3]
Which option makes sense? Stay on Free if occasional use and an unpredictable pause are acceptable. Consider a paid tier only if its current included usage and other features justify the price for you. The published multipliers cannot be converted into a dependable message count.
Grok Free versus a production API
Consumer app access and developer API use are separate budgeting questions. For example, xAI lists grok-4.7 API rates of $2 per million input tokens and $6 per million output tokens. Its model documentation says different rates apply to requests exceeding the 200,000-token context window threshold. The threshold applies to an individual request’s context—not the total tokens accumulated across a month. [4]
As an arithmetic illustration at the listed rates for requests that do not exceed that threshold, 100,000 input tokens plus 20,000 output tokens would cost about $0.32: $0.20 for input and $0.12 for output. This example assumes no cached-input discount and excludes any separately billed features. It does not establish that a particular workload qualifies for those rates; check the current model pricing and the context of each request. [4]
API rate limits are separate from consumer app limits. xAI documents per-model limits in requests per second and tokens per minute, which vary by API team tier; check your team’s current limits in the xAI Console before estimating production throughput. [5]
To estimate a production budget, identify the model and estimate monthly input and output tokens, while checking the context size of individual requests and your team’s rate limits. Without the expected workload and volume, API cost or production fit cannot be determined from the Free limit alone.
Bottom line: xAI describes Free as limited but does not publish a universal message count or fixed Free reset time in the materials reviewed. Use your account’s own notice for immediate access, compare The X Subscription’s listed prices if you need more consumer usage, and budget developer API use separately by model, tokens, request context, and team limits.
