B.AI

20x if you top up with BNB, 15x with anything else

B.AI bills DeepSeek V4.1 Flash at a tenth of the standard reference price during its running promotion, and hands out bonus credits on top-ups. How much you get back depends on how you pay: BNB takes it to 20x, every other method lands at 15x.

Open B.AI

Tiers

  • Top up with BNB — 20x$10.00 → $200.0020x
  • Any other payment method — 15x$10.00 → $150.0015x
  • The promotion alone, with no top-up bonus$10.00 → $100.0010x

What the headline leaves out

  • The BNB leg is what makes 20x possible — paying by card or Alipay leaves 5x on the table.
  • The 10x pricing leg is a limited-time promotion and B.AI does not publish an end date.
  • 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.

Multi-model gateway with its own credits ledger at 1 USD = 1,000,000 credits. Pays out in promotional pricing rather than in cash, and pays more when you top up with BNB.
