The rise of large language models pushed inference far beyond the capacity of a single GPU. Today, LLMs with 70B, 120B or even more parameters often demand multi-node deployments. As a result, teams face new challenges around memory distribution, compute efficiency and unpredictable traffic patterns. The NVIDIA Dynamo inference framework offers a response to these problems, bringing a fresh approach to distributed serving at scale.
Modern AI workloads continue to grow, and organizations need predictable performance without constant overprovisioning. Therefore, Dynamo enters the landscape as a flexible, open-source framework designed specifically for multi-node LLM inference.
Why NVIDIA Dynamo inference matters for large-scale LLM serving
Serving LLMs at scale requires careful orchestration. Traditional inference systems often struggle with resource bottlenecks, especially when long context windows mix with short decoding workloads. Dynamo tackles this by splitting tasks into prefill and decode phases. Prefill is compute-intensive, while decode is memory-bound. When companies run both phases on the same GPU, they waste resources. Dynamo avoids this by distributing the two stages across separate GPU groups.
This architectural shift improves flexibility and allows teams to optimize each stage independently. Moreover, the framework’s ability to increase GPU utilization reduces latency and keeps infrastructure costs predictable.
How disaggregation improves NVIDIA Dynamo inference performance
Dynamo’s disaggregated serving model changes how teams run LLM workloads. Instead of forcing every GPU to handle full inference cycles, Dynamo assigns compute-heavy prefill operations to specialized GPUs while decode GPUs handle memory-bound token generation.
Consider an e-commerce platform. It may process thousands of context tokens for recommendation models, yet only generate short 50-token results. Without disaggregation, GPUs remain underused. With Dynamo, however, prefill GPUs manage the heavy input, and decode GPUs handle short, repeated generation tasks. As a result, the system runs more efficiently and scales with user demand.
Dynamic scheduling strengthens NVIDIA Dynamo inference during traffic spikes
Traffic rarely stays consistent. Therefore, Dynamo integrates a dynamic scheduling engine that shifts resources based on real-time needs. A Planner component predicts traffic using time-series analysis. It also aligns resource allocation with SLA targets, such as Time to First Token or Inter-Token Latency.
When traffic surges, Dynamo can temporarily reassign GPUs from decode to prefill. When demand drops, it scales resources down. This elastic behavior gives organizations a way to maintain performance without permanent overprovisioning.
NVIDIA Dynamo inference boosts caching efficiency with LLM-aware routing
Another core capability comes from Dynamo’s LLM-aware router. It tracks where KV cache blocks live across GPU clusters. When a request arrives, the router evaluates how much of the context overlaps with already-cached data. Then it routes the request to GPUs that maximize reuse.
Consequently, Dynamo avoids redundant computation—a significant advantage when many user requests share similar prompts or histories. Furthermore, this caching strategy becomes even more important with large context windows and multi-step workflows.
Scalable memory management through KV Block Manager
LLMs often generate vast amounts of KV cache data. Dynamo handles this with a KV Block Manager that offloads rarely accessed blocks to CPU RAM, SSDs or object storage. This design extends cache capacity to petabyte scale.
Without offloading, many concurrent sessions lead to cache eviction and costly recomputation. With Dynamo’s tiered storage, however, GPUs stay available for active sessions while historical data remains accessible. This helps organizations improve throughput without increasing GPU counts.
Microsoft Azure and NVIDIA demonstrate real-world deployment
NVIDIA and Microsoft Azure recently collaborated to test Dynamo in a realistic Kubernetes environment. They deployed the framework on Azure Kubernetes Service running ND GB200-v6 virtual machines. These rack-scale instances include 72 tightly interconnected NVIDIA Blackwell GPUs.
Using the GPT-OSS 120B model and an InferenceMAX-based recipe, the team reached 1.2 million tokens per second. This result shows that Dynamo performs well in cloud environments and doesn’t require specialized, proprietary hardware stacks.
Moreover, engineers built the deployment using standard cloud-native tooling. They used GPU node pools, Helm charts for Dynamo and Kubernetes orchestration. This proves that organizations can adopt Dynamo without rewriting their infrastructure.
Open-source foundations strengthen the NVIDIA Dynamo inference ecosystem
Dynamo grows from the lessons learned with NVIDIA Triton Inference Server. The project blends Rust for performance and Python for extensibility. It is fully open source, allowing teams to customize and contribute to its evolution.
Because Dynamo integrates with TensorRT-LLM, vLLM, SGLang and other engines, it lets teams choose the runtime that fits their needs. This flexibility creates a unified serving layer that works across model sizes, architectures and deployment types.
Conclusion: the future of NVIDIA Dynamo inference in large-scale AI
The NVIDIA Dynamo inference framework arrives at a critical moment. LLMs continue to expand, and organizations need infrastructure that adapts to shifting workloads. Dynamo addresses this with disaggregation, dynamic scheduling and smart caching. As a result, teams can serve massive models reliably across many nodes, all while keeping performance consistent and cost-effective.
As AI systems keep growing, frameworks like Dynamo will shape how organizations handle large-scale inference for years to come. Ultimately, Dynamo represents a major step toward more efficient, flexible and cloud-native LLM serving.
