Sora 2 System Card

2025-09-30 · 00:00 UTC ·0 min read

Brief

OpenAI’s Sora 2 is presented as an upgraded multimodal generative model for video plus audio, with emphasis on better physics, realism, audio-video synchronization, and user control. However, the supplied text is only a brief announcement blurb rather than the substantive contents of a full system card, so technical methodology and quantitative performance evidence are absent here.

Why it matters

OpenAI announced Sora 2 on 2025-09-30 as a new state-of-the-art video-and-audio generation model building on the original Sora.

Key details

  • The model claims improvements in physically plausible motion, sharper visual realism, synchronized audio generation, stronger steerability, and a broader stylistic range than prior video models.
  • The provided excerpt is extremely short—51 words—and does not include system-card specifics such as benchmarks, safety methods, training data details, or deployment constraints.

Sora 2 is our new state of the art video and audio generation model. Building on the foundation of Sora, this new model introduces capabilities that have been difficult for prior video models to achieve– such as more accurate physics, sharper realism, synchronized audio, enhanced steerability, and an expanded stylistic range.
