Rust is the best language for AI:

- Rust code generates absolutely perfectly in Claude Code.

- Rust code will run without GC. You get that for free.

- Rust code has a low defect rate per LOC, at least measured by humans. Google gave a talk on this. The sum types + match and destructure make error handling ergonomic and more or less required by idiomatic code, which the LLM will generate.

I'd certainly pick Rust or Go over Python or TypeScript. I've had LLMs emit buggy dynamic code with type and parameter mismatches, but almost never statically typed code that fails to compile.

In this benchmark, models can correctly solve Rust problems 61% on first pass — A far cry from other languages such as C# (88%) or Elixir (a “buggy dynamic language”) where they perform best (97%).

I wonder why that is, it’s quite surprising. Obviously details of their benchmark design matter, but this study doesn’t support your claims.

The downside is that even simple Rust projects typically use hundreds of dependencies, and this is even worse with LLMs, who don’t understand the concept of “less is more”.
