OpenAI Codex now lets developers publish one prepared GitHub project setup for separate cloud coding tasks. Each task retains its uncommitted work across web and mobile sessions.

The biggest announcement of #OpenAI DevDay today was the always-on agents, named dots, for personal and business users.

It looks interesting, as a personal agent is “always available” with much richer context.

Unfortunately, the EEA, Switzerland, and the UK are excluded.

During #OpenAI DevDay GPT-6.1 Sol was announced, less than a week since the last release.

Unity×Codexで、実際に2Dゲームを1本作ってみました🎮

Playerを動かすところから始めて、戦闘・ADV・Boss・音声・Endingまで少しずつ実装。最後はWindowsで遊べるところまで完成しました。

実際に使ったCodexへの指示も含めて、全28STEPでまとめています。

Codex vs Claude Code. GPT-6 Astra vs Opus 5.5. Scary spider challenge.

Codex hit its usage limit in minutes and did an ok job across two 5-hour windows. While I waited, Claude Code did this in about an hour.

Don't believe the hype.
