Bottleneck is context quality, not LLM coding ability
The main bottleneck in AI-driven kernel optimization for new hardware is not the LLM’s ability to generate Metal code, but the quality of the structured, cross-platform translation knowledge used to guide the search.

From CUDA to MLX: How K-Search Brings Decades of Kernel Expertise to Apple Silicon
Original excerpt
For us the main takeaway is that the bottleneck was not the LLM’s ability to write Metal code, but the quality of the context and constraints we gave it.
Context
Our CUDA translation layer converts existing NVIDIA kernel expertise into actionable guidance for Apple Silicon, and lets K-Search’s evolutionary search do the rest.
