Code Arena "is our next-generation evaluation system, rebuilt from the ground up for transparency, precision, and real-world performance. Models operate as interactive agents inside controlled, isolated environments where every prompt, render, and action is logged. Sessions are restorable and persistent across visits, and generations can be shared or revisited later.The result is a live, inspectable system that evaluates not only whether code works, but how well it performs, how naturally it interacts, and how faithfully it fulfills the intended design. Code Arena measures coding in motion, capturing how models think, plan, and build in conditions that mirror real development."news.lmarena.ai/code-arena/ #AI #GenerativeAI #Programming #VibeCoding #SoftwareDevelopment #Chatbots #LLMs
