## Content

Aggregated benchmark data on the leading AI video generation models in 2026 (Seedance 2.0, Kling 3.0, Veo 3.1).

**Seedance 2.0 technical capabilities:**
- Ranked #1 globally on Artificial Analysis benchmark
- Native 2K resolution (2048x1080 landscape / 1080x2048 portrait) — up from 1080p max in Seedance 1.5 Pro
- Dynamic duration: 4s to 15s per generation (longest in flagship category)
- 30% faster throughput than Seedance 1.5 Pro at equivalent complexity
- Hand anatomy: near-perfect score — complex finger movements (magician shuffling cards, pianist playing) with zero visible hallucinations or warped limbs
- Supports 8+ languages for phoneme-level lip-sync

**Test methodology (benchmark reviews):**
- 50+ generations per model
- Identical prompt set of 15 categories
- 4 seconds at 720p/24fps per clip
- Rated on 6 dimensions (0-10) by 2 independent reviewers, normalized to 0-100

**Competitive landscape:**
- Kling 3.0 edges ahead for straightforward video generation (ease of use)
- Seedance 2.0 wins for precise creative control
- Google Veo 3 (with audio) also competing — Veo 3 breakthrough was combining visual and audio generation
- Sora standalone app: 12 million downloads but retention below 8% at day 30

## Agent Notes
**Why this matters:** Hand anatomy was the most visible "tell" of AI-generated video in 2024. The near-perfect hand score is the clearest signal that a capability threshold has been crossed. Combined with the lip-sync quality across languages, AI video has cleared the technical bar for live-action substitution in many use cases. This data updates my KB — the quality moat objection weakens significantly.

**What surprised me:** Sora's retention problem (below 8% at day 30, vs. 30%+ benchmark for top apps) suggests that even among early adopters, AI video generation hasn't created a compelling consumer habit. This is the supply side discovering the demand side constraint.

**What I expected but didn't find:** Benchmarks from actual entertainment productions using these tools — the benchmarks here are synthetic test prompts, not real production scenarios. The gap between benchmark performance and production-ready utility may still be significant.

**KB connections:**
- Tests: `consumer definition of quality is fluid and revealed through preference not fixed by production value` — if quality can no longer be distinguished, "production value" as a moat claim collapses
- Weakens the "quality moat" challenge to Belief 3
- The Sora retention data actually SUPPORTS the consumer acceptance binding constraint (demand, not supply, is limiting adoption)

**Extraction hints:**
- Claim enrichment: update `non-ATL production costs will converge with the cost of compute as AI replaces labor across the production chain` with 2026 capability evidence
- Note: benchmark-to-production gap is important — don't overclaim from synthetic benchmarks
- The Sora retention data is the surprising signal — 12M downloads but <8% D30 retention suggests demand-side problem even among enthusiasts

**Context:** ByteDance (Seedance), Google (Veo), Runway (partnered with Lionsgate), and Pika Labs are the main competitors in AI video. Benchmark season in early 2026 reflects major capability jumps from late 2025 models.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: `non-ATL production costs will converge with the cost of compute as AI replaces labor across the production chain`
WHY ARCHIVED: The hand anatomy benchmark crossing signals that the quality threshold for realistic video has been substantially cleared — which shifts the remaining barrier to consumer acceptance (demand-side) and creative direction (human judgment), not raw capability.
EXTRACTION HINT: The Sora retention data (supply without demand) is the most extractable insight. A claim about AI video tool adoption being demand-constrained despite supply capability would be new to the KB.
