🚨 OpenAI Set to Reveal a Long-Term Agent at DevDay - Codenamed "Aeon" — built for long-running tasks, similar to Grok Bot or Manus, working for hours, days, even weeks - Likely built on Astra, already strong at long-horizon work - Runs in a cloud environment like Cursor — sets everything up remotely and keeps grinding until the task's done - OpenAI already has the infra (hosted sandboxes, multi-agent workflows) to make this the natural next step - Rumored to support multiple agents collaborating on the same task — if real, that's a big deal
