Just take a look at their workflow and you tell me. NVIDIA uses an AI-powered code editor called Cursor. It is a fork of VS Code that integrates Large Language Models (LLMs) directly into the programming environment.
Here a quote from this article:
A high-profile endorsement from NVIDIA’s CEO Jensen Huang in late 2025 underscored Cursor’s rapid ascent – calling Cursor his “favorite enterprise AI service” and noting that 100% of NVIDIA’s engineers now use AI assistance with a remarkable boost in productivity.
In late 2024 and early 2025, CEO Jensen Huang explicitly stated that "every single software engineer at NVIDIA uses Cursor."
And then there is this article:

So it’s kinda obvious they use a lot of AI in their code. Now there is no direct proof they use it in their drivers but they obviously do given the CEO’s stance.
