Xie Saining's Team Unveils Solaris: A Breakthrough in Multi-User Video AI
A New Era in Interactive AI: Solaris Takes Center Stage

In a significant leap forward for artificial intelligence, Xie Saining's team at New York University has introduced Solaris, the world's first multi-user video world model. Built upon Kunlun Wanzhi's open-source Matrix-Game 2.0 framework, this technology promises to revolutionize how we think about collaborative virtual environments.
How Solaris Changes the Game
The model introduces a groundbreaking multi-player self-attention layer, enabling seamless information exchange between users. When tested in Minecraft, Solaris demonstrated remarkable capabilities in maintaining building consistency and visual alignment among players - areas where previous solutions like Multiverse struggled.
"What makes Solaris special isn't just its technical prowess," explains Dr. Xie, "but how it mirrors real-world collaboration. The system understands that when multiple people work together, they're not just sharing space - they're creating shared meaning."
The Foundation Behind the Innovation
Matrix-Game 2.0, released by Kunlun Tian Gong in August 2025, serves as the backbone of this achievement. This general scenario real-time interactive generation model fills a critical gap in AI research while showcasing China's growing influence in cutting-edge technology development.
The timing couldn't be more symbolic. Just as Solaris emerges, Xie's company AMI - co-founded with Turing Award winner Yann LeCun - announced a staggering $1.03 billion seed round at a $3.5 billion valuation. This dual breakthrough underscores the accelerating race toward artificial general intelligence (AGI).
Why This Matters for AI's Future
World models like Solaris represent more than technical milestones - they're building blocks for how machines might one day understand and navigate complex human environments. The implications extend far beyond gaming:
- Education: Collaborative virtual learning spaces with realistic interactions
- Remote Work: More natural digital collaboration environments
- Social Platforms: Next-generation shared virtual experiences
The open-source nature of Matrix-Game 2.0 means developers worldwide can build upon this foundation, potentially accelerating innovation across multiple industries.
Key Points:
- Solaris is the first multi-user video world model capable of complex collaborative tasks
- Built on Kunlun Wanzhi's open-source Matrix-Game 2.0 framework
- Demonstrates superior performance in Minecraft compared to previous solutions
- Coincides with major funding news for Xie Saining's AI company AMI
- Represents significant progress toward more sophisticated AGI systems
