Kimi K3 landed third on the Intelligence Index, ahead of Opus 4.8, and even GPT-5.6 Sol couldn’t take #1 from Fable 5. Weights supposedly drop July 27.

Been going through the Kimi K3 numbers and I don't think people have fully clocked how big this is. Right now on the Artificial Analysis Intelligence Index, Fable 5 is still #1 (59.9) and even GPT-5.6 Sol (58.9) hasn't managed to pass it. K3 comes in third at 57.1, ahead of Opus 4.8. That is an open-weights model landing within about three points of the single best closed model out there, one that OpenAI's own flagship couldn't overtake. And on the stuff that's harder to fake it's arguably better than third. It tops Program Bench at 77.8 (past both Sol and Fable), and in the blind Frontend Code Arena vote it came out first over every US model. People already had it build a full 3D open-world game in the browser with Three.js/WebGPU, a Long March 10 launch sim, and a working GBA emulator, in about a day. What gets me is the combination: 2.8T params (largest open model ever), ~1M context, priced around half of Opus per task, and the weights are supposed to go public July 27. If that holds, you can just run frontier-adjacent intelligence yourself. I'm trying to stay skeptical. A chunk of the benchmarks are Moonshot's own, the model is only days old, and the weights aren't actually out yet so nobody's self-hosted it. But even with all that, an open model getting this close to the top isn't something we've really seen before. Genuinely curious what this sub thinks: is the "even Sol couldn't beat Fable, but an open model got within three points" framing fair, or am I overrating a launch-week spike? And is anyone planning to actually deploy K3 once the weights drop on the 27th? submitted by /u/hero88645 |
