* Fixed assumptions for the example monthly cost: 100 calls/day · 2,000 input / 800 output tokens per call · off-peak rates · 30% cache hit rate · 30-day month — the same formula and defaults as the cost calculator. USD models are converted to CNY at the reference rate for comparison (see summary). Costs within display precision are marked tied; neither side is favored.
