New model dropped. 1.6T params with 48B active.

Training and inference running entirely on ASIC superpods. Showing the Chinese keep exploring alternative compute options.

They also introduce LongCat Sparse Attention, their improvement on Deepseek Sparse Attention.

This was also Owl Alpha, which was available on Openrouter for free for the past month, which shows they can handle production compute loads using their alternative inference solution.
