Uptime This Week
ChatGPT exhibited complete unavailability throughout the monitoring period, registering 0% uptime. Grok maintained continuous availability at 100%. This represents a significant reliability disparity between the two providers during this specific measurement window.
Response Time
Grok delivered a 164ms average response time during the week. ChatGPT response time data was unavailable, consistent with its zero uptime reading during this period.
Incidents & Downtime
Neither provider showed recorded incidents in Uptrue's monitoring logs, and both reported zero minutes of tracked downtime. However, ChatGPT's complete unavailability suggests a systematic issue beyond Uptrue's incident classification threshold.
Which Should You Choose?
For the monitoring period tracked, Grok demonstrated reliable availability. Teams requiring consistent access to AI chat tools should evaluate recent weeks' data alongside this period, as week-to-week performance variations are common in this category. Grok's 164ms response time is suitable for non-latency-critical applications.
