It seems there is something wrong with the packaging/config of the model.

I am running the cu130 dev build 0.5.16.dev20260713+g4cec9ef9d7 of sglang (Qwen/Qwen3.6-27B-FP8 works fine with basically auto detect/no specific cache/quant config)

bottlecapai/ThinkingCap-Qwen3.6-27B-FP8 does not work with the same setup:

Thanks for the feedback. I reproduced it.

I will let you know when we fix the issue.

Hi @Alex123563 . We just released a new fp8 quantization which should resolve the issue with SGLang.

We are still running the benchmarks but it looks very promising. Let us know if it works for you. Thx.
