| Cached input | $1.00/Mtok | $0.044/Mtok |
| Price basis | — | DeepSeek bills this model at TWO rates depending on the hour. The tracked figure is the PEAK rate: $1.32 input / $0.044 cached input / $3.96 output per 1M tokens. Off-peak is exactly half: $0.66 / $0.022 / $1.98. Peak hours are 01:00-04:00 and 06:00-10:00 UTC; every other hour is off-peak. Peak is the headline here because DeepSeek defines off-peak as half of peak rather than the other way round, so peak is the list rate, and because a caller who does not schedule around the clock needs the published number to be a ceiling rather than a floor. Halve it for a workload that runs entirely outside those seven hours. Until 16:00 UTC on 2026-08-16 this model billed a single flat $0.435 / $0.003625 / $0.87. |
