It isn't the shiny object (hardware is). It isn't the fun new language (Mojo is). But it is the reason NVIDIA’s data center revenue remains above 90% market share despite Intel’s Falcon Shores and AMD’s MI400. The 12.6 stack has achieved something no other compute platform has: in shared cloud environments.
The "Stream-ordered Memory Allocator" introduced in CUDA 12.0 has finally reached v2.0 in this release stream. The allocator now implicitly captures kernel launches into dependency DAGs without developer intervention. For high-frequency trading and real-time inference engines, this has eliminated the last 5 microseconds of launch latency. cuda 12.6 news december 2025
NVIDIA’s EULA for 12.6, updated three weeks ago, now explicitly forbids running the CUDA runtime on "non-NVIDIA hardware via translation layers" (a direct shot at ZLUDA and Intel's SYCLomatic). But more importantly, it quietly added arbitration clauses for "AI model distribution." Lawyers are poring over whether shipping a compiled .cubin binary in a Docker container counts as distribution requiring a license. CUDA 12.6 in December 2025 is like a high-efficiency water heater. You don't brag about it at parties, but you notice immediately when it breaks. It isn't the shiny object (hardware is)
