SuperGrok Heavy costs $300/mo; Kimi Vivace costs $199/mo. More usage is expected from the more expensive plan; the question is whether it buys anything else.
Kimi Vivace vs SuperGrok Heavy: we would buy neither. SuperGrok Heavy costs $300/mo; Kimi Vivace costs $199/mo. Prices are the providers' own list prices, and the verdict is ours rather than a score. The two plans are compared on what a week of real coding tasks fits, not on a feature list.Measured
Our verdict
We would buy neither. Kimi drains limits too quickly, and SuperGrok Heavy costs $300 for the slow Grok 4.7.
At this price level, buy a Claude Max plan. It gives you Opus 5.5 and Fable and costs less than SuperGrok Heavy.
$199 gives K3 ten times the agent credits of Allegretto. The usage limit still runs out too quickly. K3 has regressed in our use since release. More credits do not make it worth buying.
Pros
The largest Kimi credit pool
Good visual design
Cons
The usage limit drains too quickly
K3 has regressed since release
Best for Nobody.
How far it goes: we have not measured this plan
No graded Kimi subject at the moment; see the leaderboard for graded alternatives.
The $100 plan already has more Grok usage than we can find a use for. We have no idea what anyone would do with the $300 plan. xAI does not publish a usage multiple. Coding still runs on Grok 4.7. We do not recommend this plan.
Pros
Includes X Premium+
Cons
No use case beyond the $100 plan
No published usage multiple
The same Grok 4.7 coding model
Best for Nobody.
How far it goes: we have not measured this plan
Same Grok CLI as SuperGrok Plus with a bigger allowance - the SuperGrok Plus scorecard is the closest evidence.
