DeepSeek V4 Pro. Peak cache-miss rate, which is this dataset's standard tier. DeepSeek's own page states off-peak rates are half the peak rates, with peak hours 01:00-04:00 and 06:00-10:00 UTC Monday to Friday: off-peak is $0.66 input / $1.98 output, cache-hit input $0.022. The off-peak half-price is a time-of-day discount and is excluded here for the same reason batch and cached-input discounts are.
GLM-5.3. Latest flagship text model, per 1M tokens. Context window not stated on pricing page.
