The most (and least) reliable AI tools right now

We read the official status page behind every AI app on the dashboard every few minutes and record every incident each provider reports. This is what that data says about reliability over the last 30 days — ranked by uptime, straight from the source. The numbers below are live: they reflect the latest window every time you load the page.

Most reliable (with incidents on record)
Perplexity
99.99% uptime · 1 incident in 30 days
Most troubled
Kimi
92.77% uptime · 25 incidents in 30 days

20 of the 38 providers ranked here reported zero incidents in the window. A clean sheet isn't automatically a win — some feeds are newer or quieter than others — so the ranking below only crowns apps that have a track record to judge.

How we measure it

Uptime is derived from the incidents each provider publishes on its own official status page over a rolling 30-day window — not from our own guesses or pings. A provider that posts many small, honest incidents can rank below a quieter one; we weight for that, and the full method is on the how it works page.
