Run it
pip install "glyd[gpu]"import glyd
model = glyd.from_pretrained("Qwen/Qwen3.5-2B")Linux and an NVIDIA GPU, Ampere or later: the weights are packed on the GPU as the model loads, every one bit for bit (getting started). vLLM serves Glyd's weights too, for the models checked there (serving with vLLM).
