Ant Group and vLLM Open-Source Humming Quantized Inference Kernel Library
Open kernel-level support for extreme low-bit formats like INT1 and FP4 could make cheap quantized inference viable on commodity accelerators, not just high-end GPUs. Developers running vLLM deployments should watch the Zhenwu 810E integration as a signal of Ant building an in-house hardware stack. It also strengthens vLLM's coverage of Chinese-designed AI chips.
