VibeTensor: Can AI Build a Deep Learning Framework from Scratch?
NVIDIA researchers released VibeTensor, a complete deep learning runtime generated by LLM-based AI agents. With over 60,000 lines of C++/CUDA code written by AI, we analyze the possibilities and limitations this project reveals.

While LLMs writing code has become commonplace, what if AI agents could write an entire deep learning system software stack spanning tens of thousands of lines? VibeTensor, released by NVIDIA researchers, provides an answer to this question as an open-source project.
Today, we explore VibeTensor—a deep learning runtime fully generated by AI coding agents—examining its architecture, development methodology, and limitations.
What is VibeTensor?
VibeTensor is a deep learning system software stack implemented by LLM-powered coding agents under high-level human guidance. It's not a simple Python binding wrapper, but a complete runtime that includes a tensor/storage system, schema-free dispatcher, reverse-mode autograd engine, and CUDA memory management (streams, events, graphs).
