  • Submit task, wait 180 seconds, then poll every 10 seconds
• Cinematic quality: Sora 2 is known for ultra-high quality and cinematic narrative capabilities, one of the most advanced video generation models.
• Callback mode: Due to long generation times (several minutes), strongly recommend using callback mode.
