Sand.ai

Our mission is to advance AI to benefit everyone. @GagaAI_official & @magiai_hq are out now.

[Sand.ai @SandAI_HQ]

🌟 Highlights:
- Whole-Graph & FSDP-Aware Compilation: Breaks local boundaries. Full-graph capture for inference & layer-wise compilation for FSDP training to maximize aggressive cross-op fusion.
- Heuristic Recompute: No more manual checkpointing. Auto-preserves compute-bound ops (e.g., Attention) and recomputes memory-bound ones to slash peak VRAM seamlessly.
- JIT Extreme Offloading: Smart Compute + H2D dual-stream overlap. Keeps high "cost-performance" weights in VRAM and prefetches the rest at the last millisecond to eliminate pipeline bubbles.
- Plug-and-Play: Just 2 decorators (@magi_compile & @magi_register_custom_op) deliver system-level optimizations without complex model refactoring.

🪄 Introducing MagiCompiler: Break the Boundaries of Local Compilation for Large Models.

MagiCompiler is a unified compilation framework advancing torch.compile into a global "Compiler as Manager", conquering the VRAM and compute walls for training & multi-modality inference.

🌟 Highlights:
- Blackwell Support: Early Blackwell support via FFA_FA4 backend, leveraging HSTU function & R2P optimizations for next-gen hardware.
- Native Group Collective: DeepEP-inspired fused kernels (GroupCast/GroupReduce) to break RDMA bottlenecks and achieve zero-redundancy communication.
- Mask-Agnostic SOTA: Constant high-throughput performance even for irregular, complex masks. No more OOM or performance drops in "hard mode."
- System-Level Synergy: Dispatch Solver + Adaptive Overlap ensures near-linear scalability on H100 & B200 clusters.

📊 Performance & Benchmarks: Beating Open-Source SOTA

Great architecture is nothing without results. We benchmarked daVinci-MagiHuman against leading models like LTX-2.3, Ovi 1.1, and MoVA. The results speak for themselves:
👥 Human Blind Evals: Tested on a 100-sample dataset across multiple dimensions, achieving a massive 70.5% overall win rate!
📈 Objective Metrics:
🎬 Video (VideoScore2): Outperforms LTX-2.3 in Visual Quality & Text Alignment; superior to Ovi 1.1 across the board.
🎙️ Audio (TalkVid-Bench): Crushes the competition with vastly lower Word Error Rates (WER) for crystal-clear, accurate speech.
