Cuda Release News May 2026

If you’re building HPC simulations, training LLMs, or optimizing edge inference, here’s what changed, what broke (sorry, legacy Kepler devs), and what to benchmark first. The biggest quality-of-life shift: cuda.compile and cuda.execute are now built into the core driver API.
