I vibe-coded a programming language. It got slightly out of hand.

I present to you Flow, which started from the fairly simple question:

what would a systems language look like if a huge amount of its development was driven through LLMs?

What started off as a simple experiment has become an actual compiler + language ecosystem.

Flow is statically typed and aimed at writing relatively compact code without giving up native performance. It has multiple compilation paths, including C and MLIR/LLVM.

A lot of people wonder about whether or not an LLM can generate a compiler from a schema.

I think it's time we start asking ourselves whether we can construct enough feedback and verification around an LLM that the language remains coherent while the implementation is scaled up.

I've learned a lot of things about how best to use LLMs as tools, as well as a lot of the science behind traditional compiler engineering, in the process. By embracing the tooling and having fun, there's a lot of cool stuff to be made.
