OpenAI DevDay agenda leaks: Codex to get platform capabilities for plugins, agents and apps
testingcatalog · x · 2026-09-29
testingcatalog leaked the not-yet-public OpenAI DevDay agenda. Headline: OpenAI will build platform capabilities inside Codex, letting users develop plugins, agents, and apps right from a dedicated DevDay page.
Highlights:
- Claw Labs: Peter Steinberger on how agents change how open-source teams build
- Codex Game Studio: exploring "what makes a game easy for humans but hard for AI" by building one with Codex
- Coding agents that don't quit: an internal OpenAI agent ran over 1,000 hours keeping builds and tests passing in a large shared codebase, with goals, subagents, and persistent plans for investigating failures and coordinating fixes
The leak suggests OpenAI is positioning Codex as a platform for plugin/app development, not just a coding assistant.
