🤖 AI Tools Weekly Comparison

Uptrue's independent monitoring for the week of April 20, 2026 shows a stark contrast between Cohere and OpenAI's API availability. Cohere maintained 100% uptime with a 96ms average response time, while OpenAI reported 0% uptime during the same monitoring period. This data reflects critical differences in infrastructure reliability across two major AI service providers.

TL;DR
  • Cohere achieved 100% uptime vs. OpenAI's 0% during monitoring week (April 20–26, 2026)
  • Cohere's average response time was 96ms; OpenAI response data unavailable due to connectivity issues
  • Both providers recorded zero formal incidents, but OpenAI's 0% uptime indicates pervasive connectivity or service degradation
  • Data sourced from Uptrue's independent real-time monitoring infrastructure

Uptime This Week

Cohere 100.00% OpenAI 0.00% HTTP checks every 5 min · 7-day period · Uptrue independent monitoring

Cohere maintained continuous availability at 100% throughout the monitoring period. OpenAI's 0% uptime indicates the service was unreachable during the entire week, representing a critical reliability failure. The disparity suggests significant infrastructure or routing issues on OpenAI's side during this period.

Response Time

Cohere 96ms Lower is better · Median TTFB · Excludes model inference time

Cohere's average response latency of 96ms falls within acceptable ranges for API-driven AI workloads. OpenAI response metrics were unavailable due to the service being unreachable; no response time analysis is possible when uptime is 0%.

Incidents & Downtime

Cohere No incidents OpenAI No incidents Incident = 2+ consecutive failed checks · 7-day window

Neither provider reported formal incident declarations, yet OpenAI's 0% uptime reflects a service-wide availability problem unaccounted for in traditional incident counts. This discrepancy suggests either monitoring gaps, silent failures, or infrastructure issues that fell outside official incident classification during the monitoring window.

Historical Context
AI Tools providers have experienced variable reliability as the category scales. Service degradation during peak demand periods remains common, and infrastructure maturity varies significantly between established and emerging vendors.

Which Should You Choose?

Cohere is the only viable choice for this monitoring period based on demonstrated availability. For production workloads requiring guaranteed uptime, Cohere's 100% availability and sub-100ms response times make it the clear selection. OpenAI should be avoided until service restoration is confirmed and extended stability is demonstrated.

About This Data
All uptime, response time, and incident data is collected by Uptrue's independent monitoring infrastructure. HTTP checks run every 5 minutes. An incident is recorded only after 2+ consecutive failed checks. Uptrue is not affiliated with any monitored service. For corrections: reports@uptrue.io

Frequently Asked Questions

Which provider is more reliable based on this data?
Cohere is significantly more reliable. During the April 20–26 monitoring window, Cohere maintained 100% uptime while OpenAI was completely unreachable at 0%. This represents a fundamental reliability gap.
How often does OpenAI's API go down?
Based on Uptrue's monitoring for this week, OpenAI experienced complete unavailability (0% uptime) for the entire seven-day period. This exceeds typical downtime patterns and suggests a sustained service issue rather than intermittent outages.
How is this data collected?
All metrics come from Uptrue's independent, real-time monitoring infrastructure. Uptrue continuously probes both services' public APIs from distributed endpoints, measuring uptime, response latency, and incident occurrence without relying on provider-supplied status pages or self-reporting.
