About
Luminal compiles your model ahead of time into optimized native code for GPUs and ASICs, unlike runtime inference engines that interpret models dynamically, eliminating every layer of overhead. Models are lowered to a minimal graph intermediate representation, a pure dataflow graph with no framework overhead. The compiler then applies fusion, tiling, memory planning, and scheduling passes tuned for each hardware target, GPUs and ASICs.
