After looking up Triton this seems quite different - Triton is a high-level CUDA competitor with Python-like syntax, and this seems to be a library aimed at generating GPU assembly for micro-optimizing kernels.

Looks pretty similar to me[1]

My experience searching for "nvidia triton" coughed up oppressive number of results for the similarly named inference server but I think the Triton discussed here is https://github.com/triton-lang/triton (although the commits that I spot checked were all from @openai.com emails, not nvidia)
