Is Gemini 3.5 Flash Actually Cheaper? Measuring Retry Amplification to Find the Flash vs Pro Break-Even

Now that 3.5 Flash is generally available, it is tempting to route everything to it. But once you measure effective cost per success instead of per-call price, the decision changes. Here is a small harness to measure retry amplification and find the break-even.
