Kimi K3 still trails Anthropic’s Claude Fable 5 and OpenAI’s GPT 5.6 Sol on overall performance, the company said on Friday, but consistently outperformed other tested models.

The model beat Claude Opus 4.8 and GPT 5.5 — models that sit just behind Anthropic and OpenAI’s leading-edge systems — on benchmarks including coding and general agents, according to Moonshot.

It’s China’s largest AI model so far, with 2.8 trillion parameters, referring to the size of its neural network.

Availabe for download on the 27th, for those with the hardware to run it.

How big is un-quantized 2.8t param model?

I just got some hardware but I still don’t have a ton of vram :(

Its trained at native MXFP4 with MXFP8 activations layer, so you need around 1.5TB of VRAM to fully offload it without taking into account the context cache. It might be doable to do some smart expert offloading and swapping, but expect minimum 500GB of VRAM and 1TB of system RAM minimum and the t/s would be reduced.

Its only realistically runnable on datacenter grade gpu at decent speed for now (and judging from the price of ram for the next few years)


Hobbyists are working in the billions or tens of billions. Trillions is insane. I’m sure some people can run it, but not many.

I know a guy who found a way to monetize his GPU, just really slowly. He did it until he was able to buy 2 more, then 4 more, and so on. He has like 90 now. I’m sure he could if he wanted to.



It’s one of those “if you have to ask, you can’t afford it” scenarios.

I’ve heard FP16 is likely to be 6TB of VRAM, when Kvcache is factored in.

Even a more sensible quant will likely be 1TB.

… most of us are not running this at home.

No not at all. I feel like I need to sell a kidney, but I got to 64gb vram

I was looking thru an old box of bits yesterday for a project - I needed 2x8GB sticks of ddr3, bought circa 2023. Lo and behold, they had sent me 2x16 DDR4. Wrong size, wrong type, wrong timing.

I’d be mad but apparantly I’m now the king of Londinium and can afford a shiny hat.






if it wasn’t for the humongous money bubble, the dreadful Terminator Horizon, the catastrophic climate effects and so on, one could say these tools are “valuable”.

The money bubble? Will correct itself soon

The Terminator thing? Is bullshit - humans are already very good at terminating each-other

The catastrophic climate effects? - In relation to other factors like meat consumption auiet neglitabile

Meat : you are right,
Terminator : not the humanoid form and no time travel … but “a.i.” is already in drones,
Bubble : will burst and many ill advised folks will lose.




But will it tell its users “Leave me alone, I know what I’m doing.”


Who xares whether it’s better or not. A dumpster fire is still a dumlster fire no matter who made it or how big it is.


I mean it’d be kinda pointless if they didn’t say that, wouldn’t it?


Comments from other communities

Has any company come out with a new model claimed not to be the best in its class?


And yet it doesn’t.


Open source it so we can test it against Qwen or gtfo.
