Monarch RT brings real-time AI video to a single RTX 5090

Monarch RT is a new acceleration method that enables true real-time video generation. It’s capable of producing around 16 frames per second as seen on a single Nvidia RTX 5090 GPU. That’s a major step toward interactive video models that feel responsive enough for creative tools or live applications without requiring large server clusters.

Benchmarks comparing Monarch RT to FlashAttention show nearly 4× speedups while preserving most of the image quality. Against dense attention baselines, the authors report reaching roughly 95% of visual fidelity, with side‑by‑side examples showing minimal differences between fast and full‑quality runs.

The project has released its implementation via GitHub, including instructions for running the system locally on consumer hardware. For power users willing to invest in an RTX 5090, Monarch RT offers a glimpse of what “real-time generative video” looks like when it fits into a single desktop PC.
