InfiniAI Lab develops efficient and scalable AI models and systems by co-designing algorithms, model architectures, and hardware-aware infrastructure.
We rethink dense computation to unlock long-context and long-generation efficiency, expand model capacity at constant compute through Mixture-of-Experts and conditional computation, and study the scaling laws that govern how sparse models grow with data, parameters, and hardware.
We build the systems stack for the next generation of reinforcement-learned, tool-using agents — large-scale and asynchronous RL pipelines, agentic serving engines, and kernel- and system-level optimizations for sparse attention and MoE inference at frontier scale.
We bring generative AI into the interactive, multi-sensory loop where humans actually work and create — developing streaming text, image, audio, and video models with sub-second latency, unified multimodal architectures, and human–AI collaboration interfaces that enhance creativity rather than replace it.
We prepare infrastructure for a world where AI agents are first-class operators of the AI stack itself — systems that let agents build, deploy, optimize, secure, and evolve ML infrastructure with minimal human intervention, while remaining safe, verifiable, and robust as models and tools co-evolve.
