Key Highlights

  • The top 10 most intelligent open-source models use a mixture-of-experts (MoE) architecture
  • MoE models achieve higher intelligence and adaptability without a proportional increase in computational cost
  • NVIDIA GB200 NVL72 delivers a 10x performance leap for MoE models like Kimi K2 Thinking and DeepSeek-R1

The AI landscape is undergoing a significant transformation, driven by the adoption of the mixture-of-experts (MoE) architecture. This move reflects broader industry trends towards more efficient and scalable AI designs. By mimicking the human brain’s ability to activate specific regions for different tasks, MoE models are revolutionizing the way AI systems are built and deployed. Mixture-of-experts is becoming the go-to architecture for frontier models, and its impact is being felt across the industry.

The Rise of Mixture-of-Experts

The MoE architecture is designed to divide work among specialized “experts,” activating only the relevant ones for every AI token. This approach results in faster, more efficient token generation without a proportional increase in compute. As Guillaume Lample, cofounder and chief scientist at Mistral AI, notes, “Mistral Large 3’s MoE architecture enables us to scale AI systems to greater performance and efficiency while dramatically lowering energy and compute demands.” The benefits of MoE are clear, and its adoption is on the rise, with over 60% of open-source AI model releases this year using this architecture.

The industry has already seen significant advancements in MoE models, with the top 10 most intelligent open-source models using this architecture. Models like DeepSeek-R1, Kimi K2 Thinking, and Mistral Large 3 are pushing the boundaries of AI capability, and their performance is being further enhanced by the NVIDIA GB200 NVL72. This rack-scale system is designed to deliver strong performance for MoE models, with its 72 NVIDIA Blackwell GPUs working together as if they were one.

Overcoming Scaling Bottlenecks

One of the major challenges in deploying MoE models is scaling them in production while delivering high performance. The NVIDIA GB200 NVL72 addresses this issue with its extreme codesign, combining hardware and software optimizations for maximum performance and efficiency. By distributing experts across up to 72 GPUs, MoE models can tap into this design to scale expert parallelism far beyond previous limits. This architectural approach directly resolves MoE scaling bottlenecks, reducing the number of experts per GPU and accelerating expert communication.

Conclusion and Future Developments

The mixture-of-experts architecture is transforming the AI landscape, and its impact will be felt for years to come. As the industry continues to push the boundaries of AI capability, the need for efficient and scalable designs will only grow. The NVIDIA GB200 NVL72 is at the forefront of this revolution, delivering a 10x performance leap for MoE models and enabling the deployment of complex AI systems. With its full-stack optimizations and support for open-source inference frameworks, the GB200 NVL72 is the key to unlocking the full potential of MoE models.
