Is Grok 4 Heavy free?
The available xAI pricing information does not establish that Grok 4 Heavy is included with a free plan. xAI’s July 9, 2025 announcement placed Grok 4 Heavy in a SuperGrok Heavy tier, but that announcement is historical. The current public pricing page lists Free and paid plans without identifying a plan that includes Heavy. So don’t budget on getting Heavy for free; confirm current access and price before subscribing. (xAI announcement; xAI pricing)
The pricing page lists Free at $0/month, Plus at $8/month, Premium at $30/month, Super at $100/month, and Ultra at $200/month. It describes Free usage as limited, but does not say that any listed plan includes Grok 4 Heavy. A plan’s listed price alone does not establish Heavy access. (xAI pricing)
What should you budget for consumer Heavy access?
The current public plan page does not establish a price for Grok 4 Heavy. A third-party article dated August 19, 2025 reported SuperGrok Heavy at $300/month, but that is a historical report, not a verified current offer; the article’s subscription table omitted the Heavy tier. Don’t treat that figure as a current quote. (CometAPI’s August 2025 article)
Before paying, confirm the Heavy plan name, price, billing period, and included access in the current account or checkout details. The public pricing information reviewed here does not settle those Heavy-specific terms. (xAI pricing)
Is Grok 4 Heavy available through the production API?
The public API model catalog and price list reviewed here do not list Grok 4 Heavy or a Heavy-specific API rate. That does not rule out a private, account-specific, or later offering; it means the published information is insufficient to confirm Heavy API availability or price. Don’t use standard Grok rates as a proxy for Heavy. (xAI model catalog; xAI API pricing)
Keep consumer-plan and API budgets separate. The public pricing information reviewed here does not establish whether a consumer subscription includes API credits, so don’t assume the subscription price covers production API usage. Check the applicable API billing terms before budgeting. (xAI pricing)
Can a free third-party route substitute for Heavy in production?
Don’t assume so. A community Puter project describes calling x-ai/grok-4, but its README does not establish that it serves Grok 4 Heavy, specify a price or allowance, or document production terms. Access to standard Grok 4 is not evidence of Heavy access. (Puter project README)
Practical budget decision: use the free consumer plan only for the access its current terms actually provide; verify Heavy-specific subscription availability and price before paying; and for production, confirm that the model you need is offered through the API and check its applicable rate card. If you specifically require Grok 4 Heavy, ask xAI to confirm its current consumer availability and API access and pricing before committing.
