But this software dominance is also slowly being challenged. OpenAI developed Triton, an open-source software solution that it claims is more efficient than CUDA. Triton can only be used on Nvidia’s GPUs as of now.97 Meta developed PyTorch and then spun off the project as an open-source initiative housed under the Linux Foundation (still financially supported by Meta), and its new version performs relatively well on Nvidia’s A100.98 The benefit of PyTorch is that it can be used across a range of hardware, but on the flip side, it is not optimized for any particular chip
