DownForAI

AI Reliability Leaderboard

Compare 90-day reliability signals across 800+ AI services: confirmed incidents, community reports, monitoring confidence, and verified availability. Not a model-speed benchmark.

When most AI services have no confirmed hard outage, a single “most reliable” ranking would be misleading. DownForAI shows the underlying reliability signals instead.

How reliable is our signal?

Monitoring confidence reflects how a service is observed — the quality of our measurement, not the service's reliability.

How this leaderboard works

  • Availability = non-outage rate over a rolling 90-day window. “Down” means a hard OUTAGE only. A degraded period is not downtime — it is counted as a separate signal. A blocked or rate-limited probe is never counted as an outage.
  • Confirmed incidents exclude false positives. Community reports are user-submitted, counted as raw totals not normalized by user base, and shown as their own independent signal — a popular service naturally receives more.
  • Monitoring confidence (official API, status page, basic probe, limited, unverifiable) describes the quality of our measurement, not the service's reliability — we never rank by it.
  • Each surface is re-checked roughly every 75 minutes. Any response-time figures shown elsewhere reflect the monitored surface (often a homepage or status page) — not model inference speed or tokens-per-second.
