NVIDIA Dynamo vs Triton Inference Server: what changed for agent inference

NVIDIA released Dynamo — an open-source inference framework specifically designed for LLMs, reasoning models, and agentic systems. This is the company's response to the fundamental shift in load patterns brought about by AI agents in 2025–2026.

Why Triton no longer handles agents well

Triton Inference Server became the industry standard for inference across a wide variety of models — from computer vision to large language models. However, its architecture was built for a classical scenario: one request, one response, a fixed sequence of steps.

Modern agentic systems are fundamentally different. Within a single task, they execute numerous sequential and parallel calls to models and tools. An agent can call a model dozens of times in seconds, switching between planning, execution, and result verification. Triton was not designed for this: its optimizations target single requests with predictable load patterns.

What NVIDIA Dynamo can do

Dynamo was designed from the ground up for agentic inference requirements. The key innovation is KV-cache routing: the framework tracks the distribution of KV blocks across GPU nodes and directs incoming requests to nodes where the required cache already exists. This eliminates redundant computations when working with shared prefixes — system prompts, conversation history, baseline task context.

The fundamental difference in approach:

• Triton: load balancing based on computational power of nodes
• Dynamo: load balancing based on KV-cache state considering request context
• Support for LLMs, reasoning models, and agentic pipelines
• Open-source code, available for self-hosted deployment

For agentic pipelines where a single system prompt is used across hundreds of parallel calls, this provides tangible gains in latency and compute cost.

How this changes agentic system design

Practical analysis shows: Dynamo changes not only performance, but also architectural decisions when designing agentic systems. If previously the inference layer was effectively transparent — took a request, returned an answer — now it becomes an active participant in orchestration.

This is especially important for systems where agents work in parallel: proper routing allows grouping requests with similar context onto the same nodes, transforming KV-cache from a passive buffer into a tool for optimizing the entire pipeline.

For teams already running Triton in production, the transition is non-trivial: Dynamo offers a different deployment model and different node management logic. However, for new projects where agentic scenarios are built from the ground up, the framework becomes the logical choice.

What this means

The emergence of NVIDIA Dynamo marks an important shift: inference infrastructure can no longer be optimized solely for single requests. Agentic systems require frameworks that are aware of cache state and patterns of parallel calls — and Dynamo became one of the first open-source answers to this demand.
