OpenAI’s DevDay 2026 will Be HUGE, $500 ChatGPT Leak, Aeon and GPT 6 Minor!?
What is OpenAI preparing for DevDay 2026? We investigate the reported $500 ChatGPT Pro Max plan, Aeon, Managed Agents, Codex Cloud, Astra Minor and the model rumors ahead of September 29. 🔔 SUBSCRIBE TO BYTEFORWARD AI news, coding agents, model comparisons, benchmarks, and the things people are actually building: https://www.youtube.com/channel/UCGGHPOAzUaKsSc2yjsOeAFQ?sub_confirmation=1 My take: speed only matters if it gets useful work finished. We look at the original posts, leaked interfaces and OpenAI's existing Ultrafast demo—and what would make a premium plan worth paying for. Research cutoff: September 24, 2026. This is a pre-event analysis for September 27; leaks and predictions are attributed in the video. The reported $500 base price differs from the $600 VAT-inclusive recording. Existing-model demos are credited and are not footage of unreleased models. No personal benchmark claims. DevDay: Tuesday September 29, 10 AM PT / noon CT.
