peak rate; off-peak is half, $0.66/$0.022/$1.98, outside 01:00–04:00 and 06:00–10:00 UTC, Monday to Friday, excluding Chinese public holidays. Still billed at this model's own rate — DeepSeek walked back the 2026-09-14 plan to route the name to V4.1-Flash

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

Licence: MIT — stated on the Hugging Face model card

Watch out

Was marked for retirement on 2026-09-14; DeepSeek's changelog now says the API continues after that date with billing unchanged, until further notice, and the pricing page still lists it at its own rate. The original release note still describes the cutover. No V4.1-Pro has shipped

What we would use it for

Frontier-adjacent capability at a fraction of frontier price, with open weights — still a live endpoint after the walked-back cutover

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.
