DeepSeek's AI breakthrough bypasses industry-standard CUDA, uses assembly-like PTX programming instead (www.tomshardware.com)

PTX also removes NVIDIA lock-in.

Kind of the opposite actually. PTX is in essence nvidia specific assembly. Just like how arm or x86_64 assembly are tied to arm and x86_64.

At least with cuda there are efforts like zluda. Cuda is more like objective-c was on the mac. Basicly tied to platform but at least you could write a compiler for another target in theory.

IIRC Zluda does support compiling PTX. My understanding is that this is part of why Intel and AMD eventually didn't want to support it - it's not a great idea to tie yourself to someone else's architecture you have no control or license to.

OTOH, CUDA itself is just a set of APIs and their implementations on NVIDIA GPUs. Other companies can re-implement them. AMD has already done this with HIP.

Ah, I hoped it was cross platform, more like Opencl. Thinking about it, a lower level language would be more platform specific.

Wtf, this is literally the opposite of true. PTX is nvidia only.

Google was giving me bad search results about PTX so I just posted am opinion and hoped Cunningham's Law would work.

How cunning.
