DeepSeek V4 Peak vs Off-Peak Pricing: How to Cut Your API Bill in Half

What Changed on August 17, 2026

On August 17, 2026, DeepSeek switched its V4 API from flat pricing to peak/off-peak time-of-day pricing. Every token — input and output — now costs 2x during peak hours compared to off-peak.

• Peak hours (Beijing time): 9:00–12:00 and 14:00–18:00
• Off-peak hours: all other 17 hours of the day, plus all national holidays

The new rate card (per million tokens, cache-miss):

Model	Off-peak input / output	Peak input / output
DeepSeek V4 Flash	¥1.5 / ¥4.5	¥3 / ¥9
DeepSeek V4 Pro	¥4.5 / ¥13.5	¥9 / ¥27

That's a real 2x swing. Run the same job at the wrong hour and you pay double for identical tokens.

The Strategy: Shift Batch Work to Off-Peak

If you're running scheduled work — nightly CI, code review, test generation, doc builds, batch translation — move it to off-peak hours and cut the bill in half with zero code changes.

For a typical batch job of 8M input + 2M output tokens on V4 Pro:

• At peak: 8 × 9 + 2 × 27 = ¥126
• At off-peak: 8 × 4.5 + 2 × 13.5 = ¥63

That's a flat 50% saving, purely from scheduling.

But Peak Hours Are a Trap for Interactive Work

Here's the catch: peak hours in Beijing time are the working morning in Europe and the late night / early morning in the US. If your team is in Europe or Africa, your interactive coding sessions land exactly in the expensive window.

For interactive work you can't schedule, the 2x premium is the price of real-time responses. For everything queued, off-peak is free money.

One More Option: Prepaid Credits With No Peak Penalty

If you don't want to think about the clock, prepaid DeepSeek credits let you pay once and use tokens whenever you need them — the cost is averaged across peak and off-peak usage, with no per-request time-of-day surprises on your bill.

AiCredits sells prepaid DeepSeek V4 credits by card (no Chinese phone, no PayPal):

Plan	Price	Tokens
Trial	$3	2.5M
Starter	$5	4.5M
Standard	$9	8.5M
Professional	$19	19M

Plus a free 100K-token trial at /free-trial so you can benchmark your real workload before committing.

Bottom line: DeepSeek's peak/off-peak pricing rewards the schedulable. Batch your heavy jobs to off-peak, keep interactive work lean, and consider prepaid credits to smooth out the clock.
