list rate is the peak rate: DeepSeek's own pages call peak standard and off-peak a 50% discount, so this board has shown $1.32/$0.044/$3.96 since 2026-08-27, where it previously showed the off-peak $0.66/$0.022/$1.98. Nothing about DeepSeek's rates moved this pass — only which of the two this board puts in the price column. Off-peak is every hour outside 01:00–04:00 and 06:00–10:00 UTC, Monday to Friday

cache hit $0.022 vs miss $0.66 off-peak; reasoning effort now documented in three named levels — low, high, max — and the API added native OpenAI Responses API support with one-click Codex integration

Watch out

Priced here at the peak/standard rate. Off-peak halves it, so a job you can schedule outside 01:00–04:00 and 06:00–10:00 UTC bills at half this row — and one you cannot schedule bills at this row, not the number quoted in most comparisons

What we would use it for

Frontier-adjacent capability at a fraction of frontier price, with open weights

What this has cost, week by week

Output price at each refresh since 2026-07-30. A vendor change is the provider changing its price. Our correction means this board changed what it prints and the provider's charge did not move — the two are never merged, because publishing the second as the first would be a price rise that never happened.
