That “leaked Anthropic model” flooding everyone’s feeds? Someone actually downloaded the whole thing—over 7 TB—and it’s all random numbers
The repo is called burner22/numbat, and it claims to be a training archive for Anthropic’s next-generation, Mythos-class model.
The codename is a real name that appeared in the March Claude Code source leak, and the account was registered just a week before uploading it.
Hugging Face’s own parameter count came out to only half of what it claimed.
In the early hours, FloxUnder downloaded just a small chunk and realized that some of the weights could be calculated bit-for-bit using the tensor names as seeds.
Today, ressl downloaded the whole thing and checked it: every normalization layer and convolution kernel matched up, and the packaging itself was flawless.
The model card even says you can load it with trust_remote_code=True, which is basically letting code written by a newly registered throwaway account run on your computer.
The download count on the page is still going up.
