Now let me compile the briefing. I have strong coverage across all areas.

Model & Tool Releases
Sora killed. OpenAI's Sora web/app went dark yesterday (Apr 26). API stays up until Sep 24. Cause: compute costs, user drop from 1M to <500K MAU, copyright pressure. OpenAI is folding resources into enterprise. (OpenAI Help Center · Medium analysis)
HappyHorse-1.0 — Stealth Alibaba model (ATH AI Innovation Unit, led by ex-Kuaishou/Kling head Zhang Di) hit #1 on Artificial Analysis blind tests for both T2V and I2V. Elo: T2V 1,389 / I2V 1,398. Unified 15B-param Transformer, 1080p, multilingual lip-sync, joint audio-video generation. Apache-2.0 license, weights "coming soon," API planned Apr 30. (CNBC · Bloomberg · fal.ai)
Wan 2.7 (Apr 6) — Alibaba Tongyi Lab. Headline feature: "Thinking Mode" — chain-of-thought reasoning plans composition before generation. Unifies T2V, I2V, video continuation, ref-to-video (up to 5 person inputs), and video editing. 720p-1080p, 2-15s. $0.10/sec at 720p. Weights NOT released — API-only, a break from Wan 2.1's open approach. (Tellers.ai · InVideo guide)
Seedance 2.0 (Apr 17) — Now available via Runway API. Unified multimodal audio-video architecture: T2V, I2V, V2V with native audio, lip-sync, keyframe control, multi-shot cuts. 4-15s clips. Available on Unlimited/Enterprise plans outside US. (Runway product page · fal.ai)
SkyReels V4 (Apr 3) — First open-source model to co-generate video + synchronized audio in a single forward pass. Dual-stream MMDiT architecture. 1080p/32FPS, up to 15s. Accepts text, images, video clips, masks, and audio references. Weights not yet released despite open-source labeling — preview only for now. (WaveSpeed · HF paper)
Grok Imagine updates (Apr 21) — Video extensions now read original prompt + source clip for audio/visual continuity. Custom templates let you upload images for photo-to-video/style transfer. 1080p (Imagine Pro) confirmed for SuperGrok. (PiunikaWeb · Basenor)
ComfyUI 0.19.3 (Apr 17) — LTX text generation in default templates, HunyuanVideo 1.5 support, new Topaz API nodes for video enhancement. NVIDIA RTX Video Super Resolution node for 4K upscale. NVFP4/FP8 support gives 2.5x speed + 60% VRAM reduction on RTX 50-series. (ComfyUI changelog · NVIDIA blog)

Platform Signals
TikTok: AI labeling is now enforcement-grade — C2PA Content Credentials auto-detect synthetic media even without creator disclosure. Deepfakes impersonating real people without labels = banned. Algorithm still prioritizes watch time → search relevance → originality. AI content not penalized if labeled, but users can now filter AIGC volume. Engagement rate: 3.15% (vs Reels 0.65%, Shorts 0.40%). (Storrito · Virvid)
Instagram Reels: Originality Score now active — detects recycled clips, dupes, and low-effort reposts, with low scores significantly reducing reach. C2PA metadata triggers automatic "Made with AI" tag. (FlowShorts)
YouTube Shorts: "Inauthentic content" policy (renamed from "repetitious content" Jul 2025) deployed with enhanced detection. Mass-produced/template AI content gets demonetized. Disclosure toggle has no negative algorithm impact — YouTube says this explicitly. Key: personality must be at the heart of the video. (TubeBuddy · BossWallah)
Net takeaway: All three platforms now auto-detect AI via C2PA. None penalize labeled AI content. All penalize mass-produced/template content. The moat is originality and personality, not hiding the AI.

What's Working
• A fitness account hit 26M views using a hyper-realistic AI avatar but lost trust when caught hiding AI disclosure. Contrast: creators who label upfront report better engagement. Transparency is a growth strategy, not a tax. (AIImageToVideo)
• One TikTok creator showed an $886 payout from 2.1M views — consistent with typical RPM. Another claimed $92K in 45 days across multiple channels (unverified). (AIImageToVideo)
• A graduation drone Reel generated entirely with AI tools hit 10M views as a case study in event-style AI content. (VVideo)
• Slightly uncanny > hyper-polished: Content that feels "slightly off" interrupts scrolling, drives comments, and outperforms flawless renders. The imperfection creates engagement. (AIImageToVideo)
• AI influencer accounts with 100K+ followers are commanding $2K-$15K per sponsored post in tech, fashion, and fitness verticals. (CommuniPass)
• Viral sweet spot: 15-30 seconds, 70%+ completion rate, 15% engagement in first hour = ~3x reach multiplier. (OpusClip analysis of 13.5M clips)

Technique Watch
• Wan 2.7 Thinking Mode — compositional planning before generation is a new paradigm. The model reasons about spatial relationships, narrative logic, and element placement before committing pixels. Worth testing for complex multi-element prompts. API-only.
• Seedance 2.0 + Runway API — native audio generation with lip-sync opens a workflow where you skip separate TTS/audio sync steps entirely. Keyframe + reference image control gives director-level precision.
• ComfyUI Topaz nodes — video enhancement integrated directly into generation workflows. Combined with NVIDIA RTX Video Super Resolution node, the path from draft gen → 4K final is now a single pipeline.
• NVFP4 on RTX 50-series — 2.5x faster inference + 60% VRAM reduction in ComfyUI. If you're running local Wan 2.2 workflows on a 5090, this is a significant practical upgrade.
• Grok custom templates — upload your own image as a style/character reference for photo→video. A lightweight alternative to training LoRAs for consistent character work.

Worth Watching
• HappyHorse-1.0 weights drop (est. Apr 30) — If Alibaba actually ships Apache-2.0 weights for a 15B model that topped both T2V and I2V benchmarks, this will be the biggest open-source video model release of Q2. Watch for ComfyUI node support within days.
• Wan going closed — Wan 2.7 is API-only, breaking with the open-weight tradition of 2.1/2.2. If this holds, local/ComfyUI users lose access to the Thinking Mode architecture. Signals a broader trend of Chinese labs closing weights after proving capabilities.
• Sora API deadline Sep 24 — Anyone with Sora integrations has 5 months to migrate. Runway, fal.ai, and Replicate are the obvious landing spots.
• C2PA as universal standard — TikTok, Instagram, and YouTube all now auto-detect C2PA metadata. Creators embedding provenance data get labeled automatically. Those who don't are increasingly at risk of manual enforcement. If you're shipping AI content at scale, baking in C2PA at generation time is now table stakes.
• DeepSeek V4 released Apr 24 — not video-specific, but the broader Chinese AI competitive pressure that's driving the video model arms race (Wan 2.7, HappyHorse, SkyReels V4 all shipping within weeks of each other). (Euronews)
