The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Moonshot's[2] tech blog opens "Today, we are introducing Kimi K3" and says it is available that day; its benchmark notes are "current as of July 16, 2026", Fortune[5] reported the launch on 16 July 2026 and OpenRouter listed kimi-k3 on 2026-07-16. The weights followed on 27 July, as the launch post promised.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
