Does SGLang support NVIDIA B200 now?

[yuqie]

Hi all,

With B200, cuda12.8 and torch2.6.0 is installed. The torch would be degraded to 2.5.1 when I installed the SGLang via pip, which is not compatible with the CUDA capability of B200. I got the following warning:

NVIDIA B200 with CUDA capability sm_100 is not compatible with the current PyTorch installation.
The current PyTorch install supports CUDA capabilities sm_50 sm_60 sm_70 sm_75 sm_80 sm_86 sm_90.

And after a long time stuck it exited with the error CUDA error： no kernel is available for execution on the device

I'd like to know whether SGLang can be installed and used on the B200 now. If can, could anyone help me to install it correctly?

I’m happy to help if you could provide the B200 access. Feel free to join the slack channel. https://slack.sglang.ai
