LongCat 2.0 NVFP4

Target checkpoint with ModelOpt NVFP4 base weights and 16 BF16 over-embedding tables. The weight index references 173 base shards and 16 OE shards.

Attention/projection and over-embedding data retain their checkpoint dtypes; NVFP4 values are accompanied by their quantization scales. The tokenizer, chat template, generation settings and quantization configuration are included.

The target uses LongcatFlashForCausalLM / longcat_flash, with 38 paired layers. Use a runtime implementing this LongCat architecture and NVFP4 format; the validated runtime is the TokenSpeed LongCat implementation.
