# GPT-6 Astra Pro in ChatGPT runs agents in parallel

Full title: ChatGPT's GPT-6 Astra Pro gets faster responses, better plugin use and parallel agents for Pro users

On Oct 16, 2026 OpenAI said GPT-6 Astra Pro in ChatGPT was upgraded with faster responses and better use of plugins and tools, and that "multiple agents can tackle different parts of a task in parallel", with each agent's progress visible and finished sub-tasks open for review. It is available to Pro subscribers in the Chat tab. The X post passed 1M views within a day.

## Key facts
- OpenAI on X (Oct 16, 20:27 UTC): 'GPT-6 Astra Pro in ChatGPT got an upgrade with faster responses and improved use of plugins and tools. 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.'
- Reach: about 1.0M views by Oct 17 (fxtwitter)
- Not stated: speed figures, which plugins, how many agents run at once, or whether the change reaches the API (GPT-6 Astra Pro on OpenRouter is the same model with reasoning mode 'pro', per our model file)

## 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.
