The July 13 changelog added inline task visualizations and a multi-agent beta letting GPT-5.6 fan out concurrent subagents and merge their work. (OpenAI) It puts the orchestrate-don't-hand-code pattern inside the Codex surface as a first-party primitive. If you've been running homegrown subagent fan-outs, benchmark yours against this before maintaining your own orchestration layer. Worth noting the empirical sweet spot stays small: 3 to 5 concurrent subagents before merge overhead eats the gains.
