Summary

This article explores how LLMs' context length constraints affect programming language choices, analyzing token efficiency across 19 popular programming languages using RosettaCode data. It finds a 2.6x difference in token efficiency between the most and least efficient languages (Clojure vs C), suggesting that as AI-generated code becomes more prevalent, languages that are more token-efficient may gain advantages due to LLM context window limitations.

One of the biggest constraints LLMs have is on context length.
This is a difficult problem to solve, as memory usage rises significantly with longer context window in current transformer architectures.
I don't think the world is drowning in memory right now.
