[OpenAI 28-Day Sprint Day 12: GPT-6 Pro Multi-Agent Parallelism, Codex More Cost-Efficient] Beating AI News Flash: On Day 12 of OpenAI's 28-day product sprint, ChatGPT's GPT-6 Astra Pro has been upgraded to allow multiple agents to handle different parts of a task simultaneously. Users can view the progress of each agent individually and open completed tasks to check the results. OpenAI also stated that the new version responds faster and integrates more smoothly with plugins and tools. It is now available to Pro users. Codex and ChatGPT Work have optimized token consumption. OpenAI enables different sub-agents to reuse context, extends cache retention time, and improves request distribution to increase cache hit rates. This reduces the overhead of processing the same content repeatedly, allowing users to accomplish more tasks with the same subscription quota. Additionally, ChatGPT's dot can now be added to the iPhone home screen. After updating the app, users can quickly send messages or make calls to the dot via widgets. [Original Link]
