Uptrue's independent monitoring for the week of 20 April 2026 tracked Grok and OpenAI across the AI Tools category. Grok maintained 100% uptime with a 164ms average response time, while OpenAI recorded 0% uptime during the same period.
- Grok achieved 100% uptime for the full monitoring week
- OpenAI reported 0% uptime during the same period
- Grok's average response time was 164ms
- Neither provider experienced recorded incidents, though OpenAI's 0% uptime indicates unmonitored or unavailable service
Uptime This Week
Grok delivered complete availability throughout the monitoring period with 100% uptime. OpenAI's 0% uptime reading suggests the service was either entirely unavailable during this week or not accessible to Uptrue's monitoring infrastructure. This represents a significant divergence in platform reliability during this measurement window.
Response Time
Grok maintained an average response time of 164ms throughout the week. Response time data for OpenAI was unavailable due to the 0% uptime condition, making performance comparison impossible for this period.
Incidents & Downtime
Neither provider reported formal incidents during the monitoring week, yet the 0% uptime reading for OpenAI indicates a critical availability issue that contradicts a zero-incident classification. Grok's zero incidents and zero downtime align with its 100% uptime metric.
Which Should You Choose?
Grok demonstrated reliable service availability during this period and should be prioritized for workloads requiring consistent access. OpenAI's 0% uptime reading warrants investigation before committing production traffic; verify whether monitoring access issues or genuine service unavailability caused this result.
