Researchers from Cohere, Stanford, MIT, and Ai2 have published a paper alleging that LM Arena, which runs the popular Chatbot Arena benchmark, gave preferential treatment to major AI companies like Meta, OpenAI, Google, and Amazon. The study claims these companies were allowed to privately test multiple model variants and selectively publish only high-performing results, creating an unfair advantage in the industry-standard leaderboard.
