ZML

ZML is an inference stack that decouples AI models from proprietary hardware to run workloads at peak performance.

ZML is an inference stack designed to separate AI workloads from proprietary hardware. It prioritizes explicit, predictable, and composable systems over implicit abstractions. By focusing on the core 20% of the stack that requires vertical optimization, it achieves high-performance execution. The platform avoids Python runtimes and hidden states to minimize overhead. It serves engineers building high-performance inference solutions, including the ZML/LLMD server for LLMs.
