DeepSeek makes weekends all off-peak: no peak pricing on Saturday and Sunday

August 22, 2026 • 343 words • 2 min read

DeepSeek is tweaking its peak/off-peak pricing again — and this time it's a clear win for developers. Starting August 23, 2026, 00:00 Beijing time, weekends no longer distinguish peak from off-peak: Saturday and Sunday bill entirely at the off-peak rate.

A quick recap of the current scheme

DeepSeek's V4 API has been running time-of-day pricing since mid-August:

Peak (weekdays): 09:00–12:00 and 14:00–18:00, Beijing time.
Off-peak: everything else — at half the peak price.

That split has been the single biggest lever for anyone watching their token bill. Now the weekend just got folded into the cheap side.

What actually changes

Nothing about your code. The change is purely on the meter:

Weekdays keep the peak/off-peak split, with peak windows at 09:00–12:00 and 14:00–18:00.
Weekends (Saturday + Sunday) charge at the off-peak rate around the clock.

So a batch job you run on a Sunday afternoon — previously peak-priced if it fell in the window — now costs half. No scheduling gymnastics required.

What this means in practice

Move weekend-tolerant work to the weekend. Batch jobs, backfills, evaluations, fine-tuning runs, data processing — anything that can wait for the weekend should.
Weekdays are unchanged. The 9–12 / 14–18 peak windows still cost double, so keep retiming your weekday workloads around them.
Hobby and side-project usage just got cheaper. Weekend tinkering is the most common kind, and it's now always off-peak.

The bigger picture

This is the second pricing move in as many weeks — first the peak/off-peak split, now the weekend carve-out. The pattern is consistent: DeepSeek is using price to smooth load, nudging usage into the hours where capacity is idle. "Off-peak is half price" was the headline last time; "weekends are always off-peak" is the sequel.

For anyone building on DSH or the API directly, the practical rule is simple: weekdays, mind the two peak windows. Weekends, don't think about it.

The takeaway

Cheaper weekends are a small change with an outsized effect for individual developers and small teams — the people most likely to run heavy jobs on their own time. If you've been rationing weekend experiments, you no longer need to.
