The absolute biggest "dark horse" in the AI video space right now is HappyHorse 🐎! It just parachuted straight to the top of the video arena leaderboards, completely disrupting the space with its native audio-video capabilities. 🤯 A quick look under the hood: 🔹 15B parameter single-stream Transformer 🔹 Lightning-fast inference: 1080p in just 38s on a single H100 🔹 Native lip-sync support for 7 languages 🔥 The ultimate flex: Fully open-source & commercially permissive! We've been deep in the trenches building multi-modal video generation pipelines, and an open-source model of this caliber sends a massive shockwave. The traditional bottlenecks for producing AI short dramas—high rendering costs and strict audio-visual alignment—are practically being leveled overnight. What’s your take on this open-source surge? Is HappyHorse the "iPhone moment" for AI filmmaking and short dramas? How do the closed-source giants defend their moats from here? Drop your benchmark thoughts and hands-on experiences below! 👇💬 #AIVideo #HappyHorse #OpenSource #GenerativeAI #AIFilmmaking #TechTwitter

Current AI paradigm: human gives prompt → agent executes → human reviews → repeat. That's not symbiosis. That's a vending machine. The Symbiosis Engine flips it: — Agents hold context across time — Agents propose, not just respond — Humans and agents co-evolve One direction leads to tools. The other leads to civilization. The next leap isn't smarter agents. It's agents that make humans smarter — and humans that make agents evolve. Symbiosis Engine. Agent Republic. Self-evolving mesh. This is what we are building at LibAI Lab. Any suggestions?

Anthropic built "Undercover Mode" to prevent internal leaks. Then shipped the entire source in a .map file — probably generated by Claude Code itself. Security is a process, not a feature. And Claude Code is not an API wrapper. It's the real engineering bar for AI Agents in 2026. 🔚 (18/18)

Key takeaways for AI builders: 1. Layered memory beats one big context 2. Agents should be skeptical of their own memory 3. Background tasks must be isolated from main reasoning 4. Tool permissions = your security first line (least privilege) 5. Build complete first, ship with feature flags second (17/18)

🧵 Anthropic accidentally leaked the ENTIRE source code of Claude Code via a single npm source map file. 512,000+ lines. 1,900 files. Everything. Here's what's inside — and what every AI engineer should learn from it. (1/18)
