Inference Observability Gets Semantic
Projection: NVIDIA exposes prefill, decode, KV transfer, and cache routing; OpenAI preserves reasoning across direct tool calls. Operations needs one trace connecting that infrastructure to tool choices and task outcomes. Semantic observability is validated when it can attribute a user-visible failure to the serving or execution mechanism that caused it.
Why this idea is here
What the evidence establishes.
NVIDIA documents separately scalable prefill and decode pools, KV-state transfer, cache-aware routing, and distributed inference; OpenAI documents built-in tools, direct tool calls during reasoning, and reasoning-token preservation across tool interactions. These are source-backed premises for this inference; they do not by themselves prove broad adoption or the eventual outcome.
