Evidence boundary
What the monthly comparison proves
Standard rates and cache reads are included. Cache writes, batch discounts, long-context premiums, tools, latency, rate limits, support, taxes, and service quality are outside this comparison.
A row qualifies only when the exact model route, channel, region, mode, tier, and input/output meters match the reviewed definition. Cached input becomes mandatory when your cached-input volume is above zero.
