What the numbers mean
What this model is
Kimi K3 was published by Moonshot, in China, in July 2026. The organisation is categorised as industry.
It works in Language, Multimodal, Vision, and is recorded as doing language modeling/generation.
This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.
Answers
Kimi K3 — common questions
How many parameters does Kimi K3 have?
Kimi K3 has 2.8T parameters. 2.8T total,16/896 active experts * 2.8e12 = 50B active. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.
Who created Kimi K3?
Kimi K3 was published by Moonshot, based in China, categorised as industry.
When was Kimi K3 released?
Kimi K3 was published in July 2026.
What is Kimi K3 used for?
Kimi K3 works in Language, Multimodal, Vision, and is recorded as handling language modeling/generation. These are the areas it was designed around; they describe intent rather than a hard boundary.
What GPU do I need to run Kimi K3?
None. Kimi K3 is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
Is Kimi K3 open source?
No. Kimi K3 has not had its weights published, so it exists only as a service controlled by its owner.
