What happened
NVIDIA’s official technical blog published Streaming Tokens and Tools: Multi-Turn Agentic Harness Support in NVIDIA Dynamo, a post about making an inference server behave like a first-class backend for modern coding and agent harnesses rather than a plain text-completion endpoint.
The core point is that agentic inference has a richer contract than ordinary chat. A model turn may contain reasoning, tool calls, tool results, more reasoning, and more tool calls, all of which have to be preserved in the structure expected by the client. If the server streams tokens but reconstructs tool calls incorrectly, drops the reasoning that justified a tool call, or loses request metadata during an internal conversion, the model can receive a subtly different conversation on the next turn. The failure mode is not a visible HTTP error. It is a degraded agent that forgets why it called a tool, waits too long to execute tools, or runs with a different harness policy than intended.
