Playco cut manual fixes 50% prototyping games with GPT-6 Astra

A startup used an AI model to build game prototypes by connecting the model directly to game development engines, allowing the AI to edit scenes, test games, and validate changes within tools developers already use. The AI model produced three different themed game versions from a single foundation prototype, with most working correctly on the first attempt. This approach reduced the need for manual fixes by 50% compared to the previous model, as the AI showed improved ability to reason about space, positioning, and visual elements. The capability to quickly turn multiple game ideas into playable prototypes that developers can test and compare represents the key advance demonstrated.
