B.AI

6.7x if you top up with BNB, 5x with anything else

The 90%-off promotion ended on September 25: B.AI now bills DeepSeek V4.1 Flash and GLM 5.3 Flash at 30% of the standard reference price, and still hands out bonus credits on top-ups. BNB takes it to 6.7x, every other method lands at 5x.

Tiers

  • Top up with BNB — 6.7x$10.00 → $66.706.67x
  • Any other payment method — 5x$10.00 → $50.005x

What the headline leaves out

  • This used to be 20x. The price leg went from 10% to 30% of list at 15:00 on 2026-09-25 (Beijing time), which cut every figure here to a third.
  • The BNB leg is still the difference: paying by card or Alipay gives 5x instead of 6.7x.
  • Bonus credits expire 30 days after they are issued, and are consumed before paid credits.
  • Prices track DeepSeek's own idle/busy clock: busy hours are 09:00-12:00 and 14:00-18:00 Beijing time, Monday to Friday.
  • MiMo V2.6 Pro and Flash sit at 4x, and only if you buy with crypto. Paying by card does not get you that figure.
