DeepSeek V4 Price Increase 2026: New Peak/Off-Peak API Pricing Explained
Quick verdict
On August 17, 2026 DeepSeek moved V4 API pricing to peak/off-peak rates and raised prices. Off-peak Flash is now $0.22/M in and $0.66/M out; using off-peak hours and cache hits keeps costs low.
DeepSeek's ultra-low API pricing has been one of the biggest stories in AI for 2026. On August 17, 2026, that changed: DeepSeek raised V4 Flash and V4 Pro API prices and introduced a peak/off-peak pricing model.
The new rates are no longer the lowest in the industry, but DeepSeek remains far cheaper than GPT-4o or Claude-class models — especially if you schedule workloads around off-peak hours and maximize cache hits.
What Changed
DeepSeek replaced its flat per-million-token pricing with two rate tiers:
- Off-peak hours
- Peak hours (2x off-peak)
Peak hours are 01:00-04:00 and 06:00-10:00 UTC. All other hours are off-peak.
New Pricing at a Glance
DeepSeek V4 Flash
| Billing item | Off-peak | Peak |
|---|---|---|
| Input (cache hit) | $0.007 / 1M | $0.014 / 1M |
| Input (cache miss) | $0.22 / 1M | $0.44 / 1M |
| Output | $0.66 / 1M | $1.32 / 1M |
DeepSeek V4 Pro
| Billing item | Off-peak | Peak |
|---|---|---|
| Input (cache hit) | $0.022 / 1M | $0.044 / 1M |
| Input (cache miss) | $0.66 / 1M | $1.32 / 1M |
| Output | $1.98 / 1M | $3.96 / 1M |
Prices are from DeepSeek's official API pricing page as of August 17, 2026. DeepSeek reserves the right to adjust pricing, so always check the official page.
Old vs New
| Model | Old (flat) | New off-peak (cache miss / output) |
|---|---|---|
| V4 Flash | $0.14 / $0.28 | $0.22 / $0.66 |
| V4 Pro | $0.435 / $0.87 | $0.66 / $1.98 |
Input prices rose roughly 50-60%, and output prices more than doubled for both models. Peak rates are another 2x on top of that.
What It Means for Developers
1. Use off-peak hours
If you can batch heavy workloads into off-peak hours, you pay half the peak rate. This is the single biggest cost lever now.
2. Maximize cache hits
Cache-hit input is now $0.007 per 1M (V4 Flash, off-peak) — about 30x cheaper than cache-miss input. Structuring prompts and context to hit the cache is essential.
3. DeepSeek is still the budget option
Compared to GPT-4o (~$2.50/$10) or Claude Opus-class models, even peak DeepSeek pricing remains far cheaper. The "46x cheaper" claims from earlier 2026 need updating — at off-peak rates, V4 Pro is still roughly 20x cheaper than Claude Fable 5-style pricing.
4. Re-evaluate cost estimates from older articles
Any article or calculator built on the old $0.14/$0.28 or $0.435/$0.87 pricing is now outdated. Budgets should be re-run with the new peak/off-peak rates.
