Base model

Qwen/Qwen3.5-397B-A17B

Model Card

The model is built via a merge of https://huggingface.co/nex-agi/Nex-N2-Pro and https://huggingface.co/Qwen/Qwen3.5-397B-A17B, proceeded by On-Policy Distillation from a stronger model. We detected an incorrect upload in the previous version, where the base merged version was upload instead of the final distilled model.

We are sorry for the confusion and apologize profusely. We are working to reupload the correct model as soon as possible.
