## Definition

**PTX** — as used in this material, a term in the domain of _GPU assembly_: the low-level programming layer that sits close to graphics hardware. It appears in the explanation of why real-time video-to-video AI required GPU assembly and a new model architecture to build.

In the captured material, **PTX** appears in the context of *GPU assembly* — the low-level work of writing code that runs directly on graphics hardware. Exploring how real-time video-to-video AI works, the conversation explains that building this kind of system took **GPU assembly and a new model architecture**, not just standard model training on top of existing frameworks. That framing is what a newcomer needs to connect the term to the discussion: PTX sits in the layer of expertise closest to the GPU itself, one of the reasons this kind of real-time system was hard to build before.
