Helion now supports incorporating compiler control parameters and kernel configurations into a single search. According to a PyTorch Blog article dated October 19, 2026, PyTorch Helion searches ptxas compiler control parameters through NVIDIA CompileIQ, jointly with the original kernel configuration search, further tapping performance headroom on about 27 kernels that have already been pre-tuned. CompileIQ packages tuning results as a portable Advanced Control File (ACF); Helion supports both specifying a fixed ACF and searching multiple ACFs together as one dimension of autotuning. These compiler controls have been exposed by ptxas since CUDA 13.3. There are currently no subsequent developments.

One Search, Two Layers of Optimization: PyTorch Helion Introduces Compiler Controls with NVIDIA CompileIQ
PyTorch Helion can now search ptxas compiler control parameters through NVIDIA CompileIQ, jointly with the existing kernel configuration search, further tapping performance headroom on the roughly 27 kernels that have already been pre-tuned. CompileIQ packages tuning results as a portable Advanced Control File (ACF); Helion supports specifying a fixed ACF, and also supports searching multiple ACFs together as one dimension of autotuning. These compiler controls are exposed by ptxas starting from CUDA 13.3.
