And now, multiple agents can tackle different parts of a task in parallel. You can follow each agent’s progress and open completed tasks to review their work. Now available to Pro users in the Chat tab.’

What happened
OpenAI announced the update only in a short X post; the ChatGPT release notes were not accessible to us. Parallel sub-agents inside a single chat bring to ChatGPT’s top tier the multi-agent pattern already common in coding agents.
