Grok Bot Pro vs Ultra: Which Legacy Tier You Need

Last Updated: November 2026

Pro, Pro+ and Ultra are the three paid individual plans in the legacy Cursor family. All three include Grok Bot, and all three run the same agents with the same capability. What separates them is the size of the weekly usage grant rather than the feature set. Nobody is gated out of a capability by choosing Pro over Ultra.

That single fact resolves most of the confusion around this comparison. Nobody is gated out of a capability by choosing Pro over Ultra. You are choosing how much work you can put through the agent each week.

There is a second source of confusion worth clearing early. Ultra exists twice, once as a legacy Cursor plan and once as a tier of The X Subscription. The two carry different usage mechanics despite the shared name.

Key Takeaways

1. Same features, different volume: Pro, Pro+ and Ultra give identical agent capability. Only the weekly grant size differs between them.
2. Ultra means two things: There is a legacy Cursor Ultra and an X Subscription Ultra. Check which family yours belongs to before comparing anything.
3. No published grant sizes: Documentation gives the ordering but no numbers. Treat quoted figures as unverified.
4. Overage differs by family: Legacy plans overflow into on-demand billing if enabled. The X Subscription overflows into prepaid credit instead.
5. Switching is one way: Moving to The X Subscription is optional but permanent, and support cannot reverse it.

Those five points cover what separates the tiers and what does not. Below, the legacy family is defined and the three grants compared. Then the newer family alongside it, and what a switch actually costs you.

What are the legacy Cursor plans for Grok Bot?

The legacy Cursor plans are the subscription family that predates The X Subscription. Grok Bot is included on every paid individual plan in that family, and on Cursor Teams. There is no free legacy route to the agent.

Each legacy plan carries a weekly usage grant that resets on a weekly cadence. That grant is dedicated rather than shared, which is the structural difference from the newer model. Nothing else draws down your allowance.

Usage is metered on the Cursor account itself. Cursor's help pages (2026) confirm that your Grok account and your X account do not hold the figure. People routinely look in the wrong place for it.

If the weekly grant runs out, you can continue on demand, and Cursor bills that usage directly. On-demand has to be enabled in your billing settings beforehand, or usage simply stops until the weekly reset.

Legacy entitlements remain in force unless you choose to move. You are not being migrated automatically, and the original terms continue to apply for as long as you stay on the plan.

How do Pro, Pro+ and Ultra differ?

The difference is quantitative and nothing else. Pro is the base weekly grant, Pro+ provides a higher one, and Ultra holds the highest legacy weekly grant in the family.

No feature gates separate the three. Every subscriber runs the same agents with the same capability, on the same kind of cloud computer. There is no tier-locked tool and no performance difference.

That makes tier selection a volume question rather than a capability question. The right tier matches how much work your team puts through the agent in a typical week. That is a measurable thing rather than a judgment call.

Documentation gives the ordering without attaching numbers to it. That matters when you are sizing a tier, because you cannot calculate the right one in advance. You can only measure your consumption on the tier you have and adjust from there.

What is The X Subscription plan family?

The X Subscription is the newer structure, and it is what new customers get. Grok Bot is included on Premium, Super and Ultra. The Free and Plus tiers do not include it at all.

The usage model is the real change. According to xAI's documentation (2026), Grok Bot draws from one shared weekly pool alongside Cursor and the Grok apps. Three products compete for one allowance.

Overflow works differently too. When the shared pool empties, additional usage comes from prepaid credit that you load in advance. There is no on-demand billing on this path, so an account with no credit loaded simply stops.

Super and Ultra carry larger pools than Premium. As with the legacy tiers, the ordering is documented and the sizes are not, so the same measure-then-adjust approach applies.

Larger organisations sit outside both self-serve families. Cursor Enterprise access is enabled through an account executive, and Grok Enterprise goes through an account manager instead.

Can you link a subscription to a legacy plan?

Yes, and this is a legacy-only mechanism. Linking a qualifying outside subscription grants additional Grok Bot usage while your existing Cursor plan stays exactly as it is.

Four individual subscriptions qualify: SuperGrok, SuperGrok Plus, SuperGrok Heavy and X Premium+. You can also sign in with a Grok account holding an assigned seat on a self-serve Grok Business plan.

The allowances do not add together. Grok Bot uses whichever source grants more weekly usage. A high Cursor tier plus a high linked subscription therefore buys only the larger of the two. AiBuildrs regularly finds teams paying twice for one allowance.

SuperGrok Lite is a separate case, because it does not include Grok Bot at all. Linking it achieves nothing regardless of what your Cursor plan provides.

Your legacy plan remains the primary account throughout. The linked subscription acts purely as an alternative grant source, and metered activity still reports against the single Cursor account.

What changes if you switch to The X Subscription?

Switching is optional for existing legacy customers. If you do move, the documentation is blunt about it: a completed unification is permanent and support cannot undo it.

Three things change together. Your dedicated weekly grant becomes a shared pool. Your on-demand billing route becomes prepaid credit. Your ability to link an outside subscription stops applying entirely.

The third change is the one that catches teams out. If a linked subscription currently sets your allowance, switching removes the mechanism providing your headroom. The shared pool may then be smaller in practice than what you had.

Work out which source sets your allowance today before deciding. AiBuildrs runs that check before a client commits, because the answer frequently reverses the obvious choice.

There is no route back. Support cannot restore legacy terms once the move completes, which makes this a decision to take once and deliberately.

Which plan should your team keep?

If you hold a legacy plan that covers your weekly volume, keep it. Staying put preserves the dedicated grant, the on-demand overflow route and the linking option, and it costs you nothing to do nothing.

Move only for a reason you can name. A permanent switch in exchange for an unmeasured benefit is a poor trade, particularly when the pool is shared with two other products.

New teams start on The X Subscription by default, so the comparison does not arise. Choose a tier on expected volume, measure for a few weeks, then adjust.

It is worth noting how unusual this transparency is. Meta publishes no pricing and no usage limits for Muse, and Meta's own write-up (2026) describes the product without quantifying any allowance. Anthropic has not published limits for Claude Duet, which remains a research preview. At least the Grok Bot tiers can be ranked.

Where the work runs past what any subscription tier covers, the constraint is architectural rather than commercial. AiBuildrs builds bespoke AI systems for exactly that case.

Frequently Asked Questions

Why do online comparisons of Pro and Ultra disagree?

Usually because they mix the two plan families together. Pro and Ultra exist on the legacy Cursor side. Ultra also exists on The X Subscription, so a thread that blurs the two reaches the wrong conclusion about what either grants. Chatbot features get attributed to the agent for the same reason. Billing arrangements also change, so a comparison written a few months ago may describe tiers that no longer exist.

Is Ultra a more capable agent than Pro, or just a larger allowance?

Just a larger allowance. Both tiers run the same agent on the same infrastructure, so performance reports from one apply equally to the other. What changes is how much work you can push through before the weekly grant is exhausted. Neither vendor publishes the grant sizes, so any specific figure you find quoted for either tier is unverified rather than simply out of date.

Does Grok Bot differ between Pro and Ultra on macOS?

No. Both tiers run the same agent through the same Cursor infrastructure, so your platform does not change capability or performance. The only difference remains the size of your weekly grant. One platform detail is worth knowing. macOS and iOS draw from a single shared usage bucket rather than separate allowances. Work on one therefore reduces what remains on the other device.

Is there a standalone Grok Bot subscription?

No. The agent cannot be bought on its own, and access always arrives bundled into a wider plan. That means a qualifying legacy Cursor plan, or Premium, Super or Ultra on The X Subscription. Before buying anything, check what your existing subscriptions already include. Teams frequently hold the entitlement without realising it, then pay a second time for the same capability.

What separates Grok Bot Pro from Pro+?

Only the weekly grant volume. Pro is the entry tier for individual users, and Pro+ provides a larger quota for heavier output. Neither offers different agent features, different tools or different performance, so the choice between them rests entirely on consumption. Base it on your team's measured weekly usage rather than on any perceived technical difference, because there is no technical difference to find.

How does Grok Bot compare to Claude Duet?

They solve different problems. Grok Bot is a team of always-on agents working on a shared cloud computer, while Claude Duet is a single proactive personal agent. Duet is also far more restricted. Anthropic launched it in October 2026 as a research preview, limited to the United States. Access is for Pro and Max subscribers by waitlist, and Team and Enterprise are not supported. It checks connected accounts every few hours rather than continuously.

How is Grok Bot usage metered?

It depends on your plan family, and the two are genuinely different. On The X Subscription, usage draws from a shared weekly pool covering Cursor and the Grok apps, with prepaid credit covering anything beyond it. On a legacy plan, a dedicated weekly grant applies, followed by optional on-demand billing if you have enabled it. Metering always reports against the Cursor account in both cases.

Is switching to The X Subscription mandatory?

No, it is entirely optional for existing legacy customers, and nobody is migrating you automatically. Once you do switch, however, the change is permanent and support cannot reverse it. Keep your legacy plan if the current grant already covers your production needs. Staying preserves your existing billing path, along with the account-linking route that the newer model does not support.

Executive Summary

Grok Bot is included on every paid individual legacy Cursor plan. That means Pro, Pro+ and Ultra, and it includes Cursor Teams as well.

The three tiers are not separated by features. Official documentation describes Pro as weekly usage, Pro+ as higher, and Ultra as the highest legacy weekly grant. The agent behaves identically on all three.

Neither vendor publishes the actual size of any grant. The ordering is documented; the numbers are not. Any figure you see quoted is not coming from an official page.

If you already hold a legacy plan, staying put is usually the simplest choice. Switching to The X Subscription is permanent, and it removes the account-linking route that may be setting your allowance today.

What Should You Do Next?

Check which plan family your account is in, then check which source sets your allowance. Those two answers settle the Pro versus Ultra question faster than any feature comparison.

If the work has outgrown what a subscription tier can cover, the problem is the architecture rather than the plan. Talk to AiBuildrs about what the operation actually needs.
