Sand.ai - AI Video Generation Platform, One-Click Complete Video Output

What is Sand.ai

Sand.ai (Beijing Sanda Technology) isan AI video generation platform. The platform focuses on the autoregressive world model technical route and has now open-sourced a 15-billion-parameter audio-video modeldaVinci-MagiHuman, the distributed training component MagiAttention, and the compilation framework MagiCompiler. Its products include the world's first autoregressive video modelMagi-1, an audio-video simultaneous generation modelGAGA-1, and an overseas Video Agent. It recently completed tens of millions of dollars in financing, committed to "Advance AI to benefit everyone".

Sand.ai's Main Features

• daVinci-MagiHuman: An open-source 15-billion-parameter audio-video simultaneous generation large model that adopts a single-stream Transformer architecture to uniformly model text, video, and audio, solving the pain points of stiff AI video performances and out-of-sync audio and video.
• MagiAttention: A distributed Attention component deeply adapted to Hopper and Blackwell architectures. Through the Group Collective communication kernel, it reduces cross-machine communication volume and achieves global load balancing to support ultra-large model training and extremely fast generation.
• MagiCompiler: A training-inference integrated global compilation framework deeply optimized based on torch.compile. Through whole-graph compilation, automatic recomputation, and JIT Offload scheduling, it fully takes over the computation and VRAM lifecycle, enabling consumer-grade GPUs to run ultra-large video models in real time.
• Magi-1: The world's first autoregressive video generation large model, supporting infinite-length video continuation, 1-second-level fine temporal control, and smooth and natural motion generation, bidding farewell to the slow motion and rigidity of traditional AI videos.
• GAGA-1: China's first audio-video simultaneous generation model, focusing on the ultimate expressiveness at the "AI actor" level, achieving precise lip sync, natural facial expressions, and physical rule coherence, solving the core challenges of character inconsistency and stiff expressions.
• Video Agent: An intelligent video creation tool for overseas markets, providing a one-click complete video creation workflow.
