Prices are per million tokens: ¥ is CNY, $ is USD; time-of-day pricing is written peak / off-peak. Monthly cost is in CNY and assumes 100M input and 20M output tokens a month, no cache hits and half of calls at peak hours where that applies, cheapest first. Models priced in USD are converted at 1 USD = 6.733 CNY (PBoC central parity, 2026-10-09).
