GPT-5.4, with no manual code. Visual assets were generated by Codex using gpt-image-1.5. The showcase spans games (a browser-based FPS, a turn-based RPG), professional landing pages, real estate data visualizations, and an e-commerce storefront. Developers can also browse interactive model demos for Sora, the Realtime API, and text-to-speech.This signals OpenAI's push to position GPT-5.4 and Codex as a full-stack agentic coding stack — from logic to visual assets, no human code required. The range of app categories gives developers a concrete reference point for what vibe coding looks like end-to-end.
Head to the OpenAI developer showcase to explore each demo — turn-based RPG, FPS, e-commerce, and more. You can also submit your own GPT-5.4 or Codex project via the submission form on the page.
