Unleashing AI Inference: How NVIDIA Dynamo Elevates Open-Source Efficiency

NVIDIA has released Dynamo, an open-source inference software designed to enhance and scale reasoning models within AI factories. The efficient management of AI inference requests across multiple GPUs is essential for cost-effectiveness and for maximizing token revenue generation.

As AI reasoning becomes more common, AI models are expected to produce tens of thousands of tokens per prompt, reflecting their "thinking" process. Thus, improving inference performance while reducing costs is crucial for the growth and revenue opportunities for service providers.

Advancements in AI Inference

NVIDIA Dynamo, which replaces the NVIDIA Triton Inference Server, is specifically designed to boost token revenue for AI factories utilizing reasoning AI models. It accelerates inference communication across numerous GPUs using a method known as disaggregated serving, which splits the processing and generation phases of large language models (LLMs) across different GPUs. This enables each phase to be optimized according to its computational requirements, thus maximizing GPU usage.

Jensen Huang, NVIDIA’s founder and CEO, mentioned, “Industries around the world are training AI models to think and learn in different ways, making them more sophisticated over time.” He added that Dynamo facilitates serving models at scale, resulting in cost savings and efficiency improvements across AI factories.

With the same number of GPUs, Dynamo has shown the potential to double the performance and revenue of AI factories serving Llama models. In tests with the DeepSeek-R1 model across large clusters, Dynamo increased the token generation rate by more than 30 times per GPU.

Key Features of NVIDIA Dynamo

To enhance inference performance, NVIDIA Dynamo includes features that improve throughput and lower operational costs. Dynamo can adjust GPU allocation dynamically in real-time based on changing demand and can identify the most suitable GPUs to minimize compute time and efficiently route queries. It also allows for data offloading to more affordable storage options while enabling rapid retrieval, thus minimizing overall costs.

Dynamo is introduced as a fully open-source platform, compatible with major frameworks such as PyTorch, NVIDIA TensorRT-LLM, and vLLM. This open model supports enterprises, startups, and researchers in creating optimized services for AI models across disaggregated infrastructures.

NVIDIA anticipates that Dynamo will enhance AI inference adoption among various organizations, including major cloud providers and AI innovators like AWS, Google Cloud, and Microsoft Azure.

Innovation in Smart Routing

One of Dynamo’s standout features is its ability to manage knowledge from previous inference requests, a concept known as the KV cache. This capability allows the system to intelligently direct new requests to GPUs that have the best knowledge match, effectively reducing redundant computations and minimizing latency.

Denis Yarats, CTO of Perplexity AI, expressed excitement about leveraging Dynamo for improving inference efficiencies and meeting the demands of new AI reasoning models.

Support for Disaggregated Serving

Dynamo provides strong support for disaggregated serving, splitting the computational phases of LLMs across different GPUs. This method is particularly useful for reasoning models, allowing for individualized tuning and resource management, ultimately improving system throughput and responsiveness.

Together AI aims to integrate its proprietary inference engine with Dynamo, intending to dynamically address any traffic bottlenecks during model processing stages. Ce Zhang, CTO of Together AI, stated that the flexibility and modularity of Dynamo would allow them to optimize resource utilization effectively.

Four Core Innovations of Dynamo

NVIDIA emphasizes four key innovations within the Dynamo infrastructure that reduce serving costs and enhance user experience:

• GPU Planner: Manages the addition and removal of GPUs based on real-time user demand, optimizing resource allocation.
• Smart Router: Directs inference requests efficiently across GPU fleets to reduce unnecessary recomputations.
• Low-Latency Communication Library: Enhances data transfer speeds across devices, streamlining communication for GPU operations.
• Memory Manager: Facilitates the offloading and rapid retrieval of inference data, utilizing economical storage solutions without impacting user performance.

Dynamo will be offered through NIM microservices and will be part of a future release of NVIDIA’s AI Enterprise software platform.
