Uptime This Week

ChatGPT 0.00% Gemini 96.26% HTTP checks every 5 min · 7-day period · Uptrue independent monitoring

ChatGPT recorded zero uptime during this monitoring window, indicating a complete service failure or monitoring gap. Gemini demonstrated strong reliability at 96.26%, reflecting typical performance for the category. The disparity suggests either transient ChatGPT infrastructure issues or authentication barriers during testing.

Response Time

Gemini 125ms Lower is better · Median TTFB · Excludes model inference time

Gemini averaged 125ms response time across successful requests. ChatGPT produced no measurable response data, preventing comparison of latency performance between the two services.

Incidents & Downtime

ChatGPT No incidents Gemini 2 incidents · 695 min Incident = 2+ consecutive failed checks · 7-day window

Gemini logged 2 discrete incidents with cumulative downtime of 695 minutes (approximately 11.6 hours). ChatGPT's complete unavailability suggests either a single extended outage or systematic monitoring failure rather than typical incident patterns. Neither provider's incident data allows determination of root cause.

Historical Context
AI Tools services have shown increasing maturity in uptime consistency, though large-scale language model APIs remain vulnerable to capacity constraints and authentication changes that can affect monitoring accuracy.

Which Should You Choose?

For production workloads during this period, Gemini is the clear choice based on demonstrated 96.26% availability. However, ChatGPT's zero uptime reading warrants independent verification before making long-term architectural decisions, as it may reflect testing methodology rather than actual service state.
