Сначала вывод
- С 2026-08-16 16:00 UTC: deepseek-v4-flash по UTC пик/офф-пик; офф-пик ровно половина.
- Офф-пик miss in $0.22/M, out $0.66/M; пик ×2. Hit офф-пик in $0.007/M.
- Flat $0.14/$0.28 до 8/16 устарел.
- Водораздел: доля выхода × UTC-окно. Thinking по умолчанию вкл., та же цена.
- 1M контекст + OpenAI-совместимый
{API_BASE}. Планирование пика и cache — рычаги.
Не model id. UTC пик/офф-пик и доля выхода — водораздел.
0. Сначала вывод
2026-08-22 DeepSeek official pricing (effective 2026-08-16 16:00 UTC) splits deepseek-v4-flash (checkpoint DeepSeek-V4-Flash-0731) into peak/off-peak × cache-hit/miss × input/output. Base https://api.deepseek.com, OpenAI-compatible; 1M context; thinking on by default at same rates.
Off-peak Flash: cache-miss in $0.22/M, out $0.66/M; peak doubles to $0.44 / $1.32. Cache-hit off-peak in $0.007/M. Peak UTC 01:00–04:00 and 06:00–10:00. Legacy flat $0.14/$0.28 dead. Gemini compare: Gemini API 2026; stack: AI Agent stack.
1. Почему нет одной цены
Teams budgeted pre-Aug 16 flat rates, launched into UTC peak, and output at $1.32/M blew budgets. Others quoted off-peak input while agent loops emit ≥3× output; thinking billed the same. No cache on 80k system prompts is expensive at peak miss $0.44/M; cache-hit off-peak gap ≈31×. August 2026 adds a time axis—not Gemini Batch, not Claude seats. Claude: Claude Code 2026.
- Peak is whole-table ×2; sessions can span both windows.
- Cache-hit vs miss ≈31× off-peak—skipping cache is repeat-input tax.
- 1M context is a cap, not free quota.
- Thinking defaults on; same price.
- MCP retries at peak rebill output. Host: MCP placement.
2. Четыре измерения
2.1 Peak vs off-peak (UTC)
Peak 01:00–04:00 and 06:00–10:00 UTC; off-peak half price. Cron batch to off-peak.
2.2 Cache-hit vs miss
Stable prefixes hit at Flash off-peak $0.007/M.
2.3 Input vs output
Off-peak out $0.66 is 3× miss in $0.22; peak out $1.32 is 94× hit in $0.014. Output share is the main dial.
2.4 Flash vs Pro
Pro off-peak out $1.98 ≈3× Flash; router only.

6. Ошибки
- 1: Pre–Aug 16 flat rates—obsolete.
- 2: Input-only quotes; output $0.66 off / $1.32 peak.
- 3: Thinking-off discount—none; same card.
- 4: No cache on large system prompts.
- 5: Ignoring UTC 06:00–10:00 peak band.
- 6: Unbounded retries at peak.
- 7: Default Pro when Flash suffices.
7. 7 шагов
- Open official page; confirm 2026-08-16 16:00 UTC and peak windows.
- Run prod prompt off-peak and peak; log cache hit/miss.
- Cache system prompt and tool Schema; target >80% hit.
- Cap tool steps and daily USD; queue peak alerts to off-peak.
- Cron batch/evals to UTC off-peak.
- Move MCP off closing laptops. MCP + Cloud Mac.
- Internal rate card: off-peak/peak columns; diff invoices by UTC hour.
8. FAQ
Сколько стоит DeepSeek V4-Flash сейчас?
Off-peak miss in $0.22/M, out $0.66/M; peak doubles. Hit off-peak in $0.007/M.
Как заданы пик и офф-пик?
UTC 01:00–04:00 and 06:00–10:00 peak (2×). Billing uses API request UTC timestamp.
Thinking по той же цене?
Same price; thinking on by default.
Сравнение с Gemini?
No single sticker compare. High cache + off-peak batch favors DeepSeek input; peak output agents need $1.32/M. Gemini 2026.
Какой model id?
deepseek-v4-flash (0731). Pro: deepseek-v4-pro. Base https://api.deepseek.com.
Зачем облачный Mac?
DeepSeek sells inference only. Peak retries rebill output at $1.32/M. Cloud Mac cuts wasted output tokens.
9. Итог
После августа 2026 цена DeepSeek V4-Flash API = UTC пик/офф-пик × cache × mix in/out. При 70% выхода одно смещение по времени ~−35%. Выход, cache, пик-ретраи вместе.
