As of November 2026, LM Arena has been mentioned in one podcast episode on Lenny's Podcast (Dec 2025). A popular online leaderboard for AI models, criticized for incentivizing superficial improvements.

Arena is a public, web-based platform that evaluates large language models (LLMs). Users enter prompts for two anonymous models to respond to and vote on the model that gave the better response, after which the models' identities are revealed. Users can also choose models to test themselves via the "Direct" selection.
