Sora 2: new video+audio model and OpenAI''s first Social Network

**Sora 2** released with improvements on physical world video modeling and a new "character consistency" feature allowing real-world element injection from a single video. The model powers a new **Sora social network** app with profiles, DMs, and viral videos, emphasizing user control over likeness use. **OpenAI** employees are actively experimenting with the model. Meanwhile, **Anthropic** launched **Claude 4.5 Sonnet** with enhanced intelligence, token efficiency, and agentic tool use, outperforming some competitors and closely tracking **GPT-5-high** on benchmarks. Ecosystem support includes LangSmith integration and strong coding/math benchmark results.

It's been 1.5 years since the Sora announcement and 10 months since Sora.com was released to the public, and 4 days after Meta announced their controversial Vibes app, and Sora 2 (as leaked) released today to good fanfare (about 7x smaller by HN upvotes).

Sora 2 has good improvements on all the physical world issues that were quickly found with Sora 1-era video models - including gymnastics and figure skating routines:

The blog post mentioned "implicit" models - no explicit world model yet as many have speculated from Genie research. But there is definitely some training on video games and browser output.

Apart from the "video with native audio" feature that Veo 3 has had for months now, one standout new feature is the ability to "inject elements of the real world into Sora 2" from a single demonstration video, which OpenAI employees are clearly having a ton of fun with:

In his personal blogpost, Sama calls this "character consistency".

This feature and the model are now productized into a new Sora iOS app and website experience, gated by invite code for now, as a "cameos" feature, which is central to how the new Sora social network functions.

And yes, we emphasize the literal "social network" - as Sama promised earlier this year - the new Sora app has profiles, follower counts, DMs, and already has its first viral video.

The team (and former members) took some pains on the livestream to talk about the safeguards put in place, e.g. an anti-doomscrolling timeout.

The cameos are all self uploaded videos as part of the onboarding, and you can set permissions in place for others to use your likeness (or not). Notably, Sam Altman's likeness is available for everyone to use, so that's why you'll be seeing a lot of deepfakes of Sam in your social feeds over the coming days.
