What it does
OpenAI's general-purpose assistant: chat, image creation and Codex coding help on the web, desktop and mobile; usable for concept images, placeholder art and gameplay code.
Agentic 3D world building: concept art from a sentence, then matching 3D props, modular building kits, PBR materials and whole buildings from a floor plan, exported to your engine.
Verdict
For concept images and coding help on one subscription; OpenAI's terms assign Output to you on every plan, including Free, but similar output can go to other users.
