xAI expanded Grok Bot access in August 2026, granting full inclusion to SuperGrok Plus and Heavy subscribers while offering only limited free trials to others, consistent with its tiered pricing that reserves agent capabilities for paid plans. The longstanding free tier at grok.com and on X delivers basic chat with usage caps and lighter models, but excludes Grok Bot and advanced features like image generation, which moved behind paywalls earlier in 2026 to manage compute costs. This approach mirrors broader industry moves to monetize frontier tools amid competition from other large language models, with traders watching for any shift in usage policies or new announcements around model releases such as Grok 4.7 that could expand free access.
