What Hacker News says
5 sources> They didn't publish the tools they used to train the model.
That's not totally true - for example Ziphu (Z.ai, developers of GLM) have published their Slime RL-training framework, developed together with Tsinghua University.

Also, if you read Moonshot's Kimi 3 report, it does give a lot of architectural detail and details on training.

Some discussion on this by HuggingFace here:

Yes, we all realize that "open weights" is more accurate than "open source", and anyways the source code would not be very interesting - it's the training data and methods that mostly define these models.
In Running Kimi K3 on MI355X at Better Performance per Dollar Than B300It stands for Sigmoid Tanh Unit Gated Linear Unit. Check the tech report/paper (page 7): https://github.com/MoonshotAI/Kimi-K3/blob/main/k3_tech_repo...
