xAI has launched two new tiers for its AI assistant, Grok: Business and Enterprise. These tiers are designed for secure, large-scale collaboration and data protection, ensuring user company data is not used for AI model training and is GDPR compliant. Both tiers offer increased access to Grok's advanced models (Grok 3, 4, and 4 Heavy) and integration with tools like Google Drive. The Business tier is for SMBs via a self-serve process, while Enterprise offers advanced management features for larger organizations.
