> Kimi K3 is Kimi’s most capable model to date, with 2.8 trillion parameters.

This puts them on the top of the largest open models list:

  Kimi K3            2.8T
  DeepSeek-V4-Pro    1.6T (49B active)
  Kimi K2.6          ~1T (32B active)
  GLM-5.2            754B (40B active)
  DeepSeek-V3.2      685B
  Mistral Large 3    675B

That's one mighty large model! Moonshot is going to need the USD 500 million reportedly raised earlier this year to run this model.

I guess it remains to be seen whether this will be open-weights. We don't even know how many active params at this point.

The K3 marketing popup when I look at the Kimi Code page says "Kimi K3 Open Frontier Model". So, if it's not going to be open, they haven't told the whole team, yet.

The article says weights will be released in the coming days, and hints it's likely around 50-70B active params.

It did say that, but it doesn't any longer.

What's the URL of the article that used to say that?

https://platform.kimi.ai/docs/guide/kimi-k3-quickstart this one, it used to have more information about the model itself, similar to the K2.6 and K2.7 pages.

Edit: OpenRouter still describes it as an open-weight model: https://openrouter.ai/moonshotai/kimi-k3

Guess we'll see!

That's a quickstart page for using the model on the platform not a page about the model. I am skeptical you are correct that it said something about model license earlier.

Edited: I was wrong.

Not the person you're responding to, just a person who still has the original version of the page open in their browser. Quoting from it:

"Kimi K3 is the first open-source model to reach the 2.8-trillion-parameter scale. It is the latest step in Kimi's continued push of model-scale boundaries: in 9 of the past 12 months, Kimi models have set new records for open-source model scale."

The page has definitely changed.

(I'm not sure why you would be skeptical of somebody recollecting something they probably read only half an hour earlier.)

		I was skeptical because the 2.6 getting started description doesn’t say open source either. I do however appreciate the correction.

Right now, if you search https://www.google.com/search?q=kimi+k3+open+weight the blurb under the quickstart page contains the removed text.

Ling/Ring 1T-A50B and the new Inkling 975B-A41B deserve to be on that list.
