Most AI-made games you see shared online were built with Claude. These are the ones whose makers say they used OpenAI's models: ChatGPT, GPT Astra, GPT-6.1 Sol or Codex. Two were made with GPT alone; in the other three, GPT did one part of the job and Claude did another. All five run free in a browser.
