OpenAI’s ChatGPT release notes for October 16, 2026 list two changes. First, GPT-6 Pro in the chat tab gained faster responses, improved use of plugins and tools, and “Multiple agents that can work on different parts of a task in parallel.” Users can follow the agents’ progress in the conversation and open completed tasks to see what each agent did. The update rolled out to eligible Pro users, with availability in managed workspaces depending on workspace settings.
Second, OpenAI introduced ChatGPT Slides, which lets users create presentations from a conversation, files or an outline, or from an example deck that guides style and layout. Text, images, shapes and charts can be edited directly or by asking ChatGPT; teammates can edit the same deck in real time and leave shared comments. Decks can be presented from ChatGPT, exported to PowerPoint, PDF or Google Slides on the web, or opened in PowerPoint or Keynote from the desktop app. Slides rolled out to eligible Pro, Business and Enterprise users with Space access.
Both changes came nine days after OpenAI brought GPT-6 with Intelligent UI to ChatGPT on October 7.
Why it matters: parallel sub-agents had been a developer-side pattern in coding tools; putting them in the main chat of a consumer subscription product makes multi-agent decomposition a default way of answering a hard request, visible to the user.
What it does not show: the release note gives no latency figures, no quality results, no limit on how many agents run, and no explanation of how multi-agent work counts against a plan’s usage allowance.
