GPT-6 아스트라 프로모션 비디오 프롬프트

Check OpenAI's official X account and announcements, collect official videos and demos of `GPT-6 Astra` and related technologies, and edit them into a 1-minute cinematic promotional video. At the beginning, include a motion graphic of a beautiful nebula like Andromeda rotating, with stars and dust gathering to form the text "GPT-6 Astra". In the main part, carefully select the confirmed key features, use cases, and related announcements, and present them with collages, smooth transitions, beautiful effects, concise subtitles, and music-synced editing. End with the nebula and title, keeping the entire video within 60 seconds.
