# Deploy GLM-5.2-Vision (NVFP4 build) on Baseten with Truss.
#   uvx truss push --config config_nvfp4.yaml
#
# There is no checkpoint assembly here: the public Hugging Face repo below is
# already the fully assembled checkpoint (GLM-5.2 text + MoonViT vision tower +
# trained projector + processor remote code), so start_server.sh only installs
# the plugin and launches SGLang.
#
base_image:
  # SGLang 0.5.13, CUDA 13, Blackwell (sm_100). Ships the DSA sparse-attention and
  # trtllm-gen fp4-MoE kernels this checkpoint needs.
