According to Sawyer Merritt, the Grok image generation feature powered by AI on X (formerly Twitter) has shifted to a subscription-only model, now accessible exclusively to X Premium and X Premium+ subscribers (source: @SawyerMerritt). This move highlights a growing trend among social media and AI platforms to monetize advanced AI capabilities, encouraging paid user adoption and driving new revenue streams. For businesses and AI developers, this signals an emerging opportunity to create value-added generative AI services tailored for premium-tier users, reflecting a broader industry shift toward subscription-based AI access and differentiated digital offerings.
