- This monitoring period covered the week of 20 April 2026 and reflects real-world user-facing availability
Uptime This Week
Runway delivered complete availability at 100% uptime throughout the week, while ChatGPT failed to register any measurable uptime from Uptrue's monitoring perspective. This stark difference suggests ChatGPT experienced persistent accessibility problems during this period that prevented normal service connections.
Response Time
Runway maintained an average response time of 89ms, demonstrating consistent performance. Response data for ChatGPT was unavailable, consistent with its 0% uptime status.
Incidents & Downtime
Both providers reported zero formal incidents during this week according to their own records. However, ChatGPT's complete unavailability as measured by Uptrue indicates that real-world service disruption occurred despite no official incident declaration.
Which Should You Choose?
For mission-critical applications requiring guaranteed availability, Runway's 100% uptime during this period makes it the more dependable choice. Organizations currently reliant on ChatGPT should implement failover strategies or alternative AI providers until service stability improves.
