Any objective research on which languages are best for AI agents?

Question

I keep reading articles that suggest that Rust or Go or some other language is optimal for AI development because of feature X or lack of issue Y.Has there been any actual head to head comparison of this using frontier models? Any benchmarks that purport to measure this?

The frontier moves quickly enough that empiric testing is often out of date by the time that it&rsquo;s published.

Theo video based on data from Tencent's Autocodebench: https://youtu.be/iV1EcfZSdCM
Conclusion: Elixir was the best (had the highest problem solve rate).
Reasons (Theo's interpretation):
- code collocation, where documentation is integrated directly within the source code
- design philosophy of a language (readability, clear idioms, and strict expectation management)

DSLs work especially well with LLMs. DSLs focus on a narrow set of concepts in a single domain.

Which language is worst for AI? Just curious.
