PINNACLE Benchmark Scores Cost per Correct Task: Models Are Good Enough, Who Decides?

CTO Advisor covers Signal65's PINNACLE benchmark, which scores whether the job comes out right, how fast, and what it costs — measuring cost per correct task, far better than measuring AI productivity by token consumption (like judging a cab service by gasoline burned).

Core argument: "the models are good enough." For large classes of enterprise work, several models suffice; the question is no longer which is smartest but who decides when to escalate — an architecture question, not a benchmark one.
The author's deskside testing shows smaller models delivering 80%–100% of frontier-model capability; in a recent lab, DeepSeek V4 Flash swept a 22-task repair pool twice.
Caveats: local models can be slower, need more deterministic scaffolding, and hit capability ceilings on some agentic tasks.
