GPT-6 Astra (released September 3, 2026) is for complex reasoning and coding, GPT-6.1 Sol (September 29) balances intelligence and cost, and GPT-6 Luna (September 22) handles high-volume work. Its GPT Image 2.5 models, released September 8, generate and edit images.
Codex is the tool most games on this page name. It works on a project from a terminal, an IDE extension, the ChatGPT desktop app or the cloud, and every ChatGPT plan includes it, Free too. An API key also works in the CLI and IDE. Its built-in image generation makes sprite sheets and can ask for transparent backgrounds, and Codex supports MCP, the protocol behind Unity's official editor server.
