Kimi K3 weights go live — Jensen Huang breaks his X silence on open models

The headline event is the release of Kimi K3's weights, the open model from Moonshot. The original piece frames it against an industry that keeps arguing about whether open models can keep up with closed ones.

A second beat: Jensen Huang, who had been quiet on X, weighed in to defend open models as a category. That part matters because the tone from the GPU side has shifted over the last year toward acknowledging that open weights are a real part of the ecosystem, not just a research curiosity.

The piece also reportedly benchmarks Fable 5 as hallucinating more than K3 on the same prompts. I am treating that comparison as a reported claim, not as a result I have verified myself.

The practical section is the one most people will care about: what it actually takes to run a 2.8T-parameter model locally. The original piece walks through the hardware and runtime choices. The honest summary is that 'running it yourself' is a real but heavy project — not a single box, not consumer hardware.
