Everyone says the new Gemini model is better. Almost no one proves it.

A newer Gemini model can sound better and still perform worse in production. Better writing does not mean better discipline, lower cost, or safer behavior. If you compare models by s instead of real workflows, you are not evaluating - you are guessing. In this post, I break down how to compare Gemini versions honestly: task success, instruction fidelity, latency, cost, and hallucination risk.
