Profile

Hi HN,I’m Padam, a developer based in Dubai.Over the last 2 years I’ve been experimenting with the idea that AI inference might not require GPUs.Modern LLM inference is often memory-bound rather than compute-bound, so I built an experimental system that virtualizes GPU-style parallelism from CPU cores using SIMD vectorization and quantization.The result is AlifZetta — a prototype AI-native OS that runs inference without GPU hardware.Some details:• ~67k lines of Rust • kernel-level SIMD scheduling • INT4 quantization • sparse attention acceleration • speculative decoding • 6 AI models (text, code, medical, image,research,local)Goal: make AI infrastructure cheaper and accessible where GPUs are

The company sits in the show hn launch segment, where it competes on its core product or service.

The company is listed at the Show HN launch stage of development.
