OpenAI announced that GPT-6 Astra Pro can split requests among parallel agents and let users open each agent’s progress and completed results. Availability currently covers some Pro accounts in ChatGPT chats, with no confirmed expansion schedule for other plans. The company also says response speed and tool use improved, but disclosed no measurements, maximum agent count, or method for charging parallel work against limits. This is an enhancement to an existing product, not a new foundation-model launch. Interdependent work does not necessarily become faster because integrating results adds costs.
