About OhMyGame
OhMyGame is an open-source studio for making games with AI. Start with a note, a reference or a character, generate images, video and 3D assets, and let an agent write the code in a real project, connect the assets and playtest the game on desktop and mobile. For the agent you can sign in with a subscription you already have, such as ChatGPT Plus or Pro or Anthropic, or paste an API key.

Yes. Your ChatGPT Plus or Pro subscription, through OhMyGame's provider sign-in. OhMyGame's own page says: "Sign in with a subscription you already have, such as ChatGPT Plus/Pro or Anthropic, or paste an API key."
