• The GPU optional dependency pins sglang==0.5.10, but the GPU Docker image is based on lmsysorg/sglang:v0.5.3rc1-cu126. This version skew can lead to runtime/API incompatibilities or pip attempting to replace the preinstalled SGLang. Consider aligning the base image tag with the Python dependency version (or loosening/pinning them consistently).
