| Price basis | DeepSeek bills this model at TWO rates depending on the hour, on the same schedule and at the same numbers as deepseek-v4-flash. The tracked figure is the PEAK rate: $0.44 input / $0.014 cached input / $1.32 output per 1M tokens. Off-peak is exactly half: $0.22 / $0.007 / $0.66. Peak hours are 01:00-04:00 and 06:00-10:00 UTC; every other hour is off-peak. Peak is the headline because DeepSeek defines off-peak as half of peak rather than the other way round, so peak is the list rate. Image input bills at the same per-token rates once the image is tokenized; DeepSeek's rate card prints no separate per-image charge. | Verified against Google's Gemini API pricing page (ai.google.dev) on 2026-07-28: the Gemini 3.5 Flash-Lite Standard paid tier is $0.30/1M input, $2.50/1M output, $0.03/1M context caching (batch tier $0.15/$1.25). The identical $0.30/$2.50 price shared with the deprecated Gemini 2.5 Flash reflects Google's uniform Flash tier pricing, not a placeholder — the value matches LiteLLM gemini/gemini-3.5-flash-lite. |
