Game development

Develop games with Codex, from the first playable loop to production quality.

Codex, combined with image generation, is particularly powerful to create browser-based and other types of games. These use cases will help you turn ideas into live games.

Build the first playable loop

Ask Codex to turn a game brief into a browser build with assets, controls, and a loop you can test.

Tune UI and controls

Use Codex to adjust HUD details, menus, controls, and small interaction issues after the game is running.

Tackle hard game logic

Leverage Codex to iterate on complex game algorithms by running a self-evaluation loop.

Triage bugs from real signals

Use Codex to gather bug reports, failing checks, logs, and repro notes into a prioritized list before it patches the game.

Review before merge

Have Codex in GitHub automatically review PRs and catch regressions and missing tests for faster deployment.
