**xAI has kept full Grok Bot access—its autonomous AI agents for multi-step tasks like research, bookings, and tool integration—behind paid tiers despite expanding the core Grok chatbot's free tier.** Recent October 2026 plan updates replaced SuperGrok with an X Subscription structure offering Free, Plus ($8), Premium ($30), and higher tiers, where Grok Bot features roll out starting at Premium. Free users receive capped basic chats, voice mode, and limited web/X search, while advanced reasoning, higher rate limits, coding tools, and agent capabilities require subscriptions to cover compute costs. This aligns with xAI's pattern of limited-time free model access (e.g., earlier Grok 4 rollouts) followed by paid upsells for heavier or specialized use. Traders are watching for any announcement expanding Bot trials or free availability amid competitive AI agent launches.
