System One vs LLMs — detailed note 1. In production AI, comparison choices should be evidenced with paired evaluations, explicit latency definitions, and clear separation between vendor claims and independent measurements. Workstation repeats this discipline across Insights pages so engineers can trust the surrounding narrative when they deep-link from Jobs, Agents, or Automation pages. When in doubt, open the Benchmark Lab filters and read the “what this does not prove” panel before citing a number externally.
