Sora 2
OpenAI's video model with synchronized audio and real-world physics — plus Cameos that put you in the scene.
About
Sora 2 (September 30, 2025) is OpenAI's second-generation video model: synchronized dialogue, sound effects, and music generated alongside video, physically-plausible motion (basketballs rebound correctly; gymnastics hold together), and multi-shot prompting. OpenAI called it the "GPT-3.5 moment for video."
The headline product feature is Cameos: verify your likeness once, then insert yourself (or consenting friends) into generated scenes with matched appearance and voice. Launched with a TikTok-style iOS social app (invite-only, US/Canada at launch; 1M+ downloads in under five days, per media reports). Closed and commercial — API access via OpenAI; free tier with "generous limits" constrained by compute. All outputs watermarked with metadata identifying AI generation.

Benchmarks
No standardized public benchmarks. Provider-claimed (OpenAI): physics accuracy and motion quality leadership — treat as provider-claimed. Independent: massive launch reception; comparative quality rankings vary by evaluator.
Provider-reported unless a source says otherwise. Benchmarks are marketing-adjacent by nature — treat them as directional.
Use cases
Trust score — 8/10
Scored 8/10 (verified tier). The reference commercial video model: synchronized audio+video, genuinely improved physics, and enormous real-world adoption (1M+ app downloads in days). Docked two points: (1) closed and commercial with compute-constrained free access; (2) quality claims are provider-reported, and the Cameo likeness system raises consent/moderation questions still being worked out.
How the trust score is built
Full methodology →- Adoption · stars/downloads, log-scaled vs peers
- 10.0/10
- Maintenance · recency, releases, issue load
- 5.0/10

- 4.5/10
- Manual review · sanity read + red-flag check
- 9.0/10
- · provider-tier estimate — thinner evidence (no public adoption metric)
- · 1M+ app downloads in under five days (media-reported); no public API adoption metric
- · released 378 days ago
- · manual review: reference commercial video model; synchronized audio+video, improved physics; Cameo likeness system raises consent/moderation questions; license: proprietary — API/app only, no weights; compute-constrained free tier
