Sora 1 vs Sora 2
Compare OpenAI's Sora 1 and Sora 2 AI video models. See the upgrades in audio, realism, control, and availability, and what to expect from the next generation.
Understanding Each Model
Sora 1: The Pioneering Vision
OpenAI's original Sora, released in December 2024, revolutionized text-to-video generation. It allowed users to create high-quality, 1080p videos from text prompts, supporting various aspect ratios. While groundbreaking, it was primarily a visual model, requiring external tools for audio integration.

Sora 2: The Next Evolution
Sora 2, slated for release on September 30, 2025, builds upon its predecessor's foundation with significant enhancements. A core upgrade is the addition of native synchronized audio, eliminating a major post-production step. It also promises vastly improved physical accuracy and finer control over generated content.

Detailed Analysis
Quality & Realism
Sora 1
Delivered unprecedented visual quality for its time, capable of generating highly realistic and complex scenes. However, it had known limitations in maintaining perfect physical accuracy and object consistency.
Sora 2
Significantly improved physical accuracy and motion consistency. Promises to deliver an even higher level of realism with fewer visual glitches and more believable interactions between objects.
Audio Support
Sora 1
No native audio support. Required users to add voice, music, and sound effects in post-production, impacting overall workflow efficiency for projects requiring sound.
Sora 2
Native synchronized audio generation including speech, sound effects, and ambient audio. This eliminates a significant bottleneck in the video production pipeline.
Control & Controllability
Sora 1
Baseline prompt control with remixing, blending, aspect ratio, and simple constraints. Good for basic text-to-video generation but limited in fine-grained control.
Sora 2
More fine control in prompts with stronger fidelity to user direction. Enhanced control over generated content including the ability to insert user likenesses into scenes.
