xAI has expanded Grok Bot access to free tiers with usage limits across X, grok.com, and mobile apps, directly boosting availability for non-subscribers. This follows July 2026 rollout of Grok 4.5 to free users and August updates widening Grok Bot trials to encourage developer adoption amid competition from models like Claude. Trader sentiment reflects xAI’s strategy of prioritizing broad reach over paywalled exclusivity, with free-tier confirmations holding through early October 2026. Key upcoming factors include further bot feature releases and any shifts in rate-limit policies that could influence resolution criteria for availability thresholds.
