alt Hacker News> Only in a very rudimentary sense and definitely not in a working compilation (much less binary equivalent) sense.
Working is the easy part; the hard part is getting something that classifies as readable C. LLMs do not really help reach the "working compilation" part but benefit from it.
We are way past "working compilation" when it comes to LLMs. They are already really good at writing readable, compliable code. The big problem with LLMs is making sure the output binary actually does what you wanted it to do. But if you define the goal not merely as instructions in a vague, unspecific human language and rather as recreating a given set of binary instructions after compilation, this big drawback goes away. So in a sense they are better suited for recompilation projects than for developing new applications.
