BAAI's ExoActor framework uses video generation models as a robot's imagination — generating third-person videos of task execution and translating them into physical humanoid robot behaviors on Unitree G1 hardware.
A 3D multiplayer game where you prompt any spell in natural language and Gemini generates working code in real-time. $6/mo VPS with spell caching.
IBM's Granite 4.1 8B dense model matches 32B MoE benchmarks while running on consumer hardware. 20x token efficiency vs Qwen.
HeyGen open-sourced HyperFrames, an HTML-native video rendering framework built for AI agents. 13,000 stars in 7 weeks, Apache 2.0 license, agent skills for Claude Code/Cursor/Codex.
Stanford/UIUC/NVIDIA/MIT team introduces RecursiveMAS: multi-agent systems that pass latent representations instead of text. +8.3% accuracy, 2.4x faster, 75% fewer tokens.
An autonomous agent loop optimized a RISC-V CPU core on FPGA hardware — 73 hypotheses in under 10 hours, +92% over baseline. But the real insight isn't about the agent. It's about the verifier that caught 63 bad ideas along the way.
Meta's Tuna-2 proves pretrained vision encoders are unnecessary. Direct pixel embeddings achieve SOTA on OCR, counting, and perception benchmarks—no CLIP, no VAE.
Microsoft's VibeVoice: 90-minute single-pass voice synthesis, frontier open-source models that beat ElevenLabs on MOS benchmarks
Poolside's Laguna XS.2 and M.1 MoE models feature the Muon optimizer—a novel training method that cuts steps by 15% vs AdamW. XS.2 is Apache 2.0 licensed, local-ready.
