Better analysis does not guarantee a better-looking deliverable. Artificial Analysis' Grok 4.7 evaluation reported that its knowledge-work gains were driven by analytical quality, while its presentation score was slightly lower than Grok 4.6's.

eval — A repeatable test for AI quality — a set of tasks plus scoring — used the way software teams use test suites, because model output is too variable to judge by eyeballing.
agent harness — The scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.
AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
token — The chunk of text a model reads and writes in — roughly three-quarters of a word — and the unit AI usage is billed in.
