Sora 2 - Free AI Video Generator

OpenAI's next-generation video model with stunning realism and native audio

Sora 2 is OpenAI's second-generation video model, building on the original Sora that stunned the world in early 2024 with its physics-aware video generation. Sora 2 takes this further with improved temporal coherence, more accurate physics simulation (fluids, cloth, collisions), and the ability to generate complex multi-character scenes with distinct emotions and interactions. It supports native audio generation — producing synchronized dialogue, sound effects, and ambient audio alongside the video. Sora 2 offers up to 12 seconds of continuous video at 720p resolution, with a 10,000-character prompt limit — the longest of any model on Genkee AI — allowing extremely detailed scene descriptions. Unlike using Sora through ChatGPT (which requires a $200/mo Plus subscription), Genkee AI gives you access with a simple credit-based system and free trial credits for new users.
