TKBK sells balance in rubles: $1 of balance = 5.8 RUB on the site, while a real dollar is 79.46 RUB (CBR, 2026-08-01). The table converts what you really pay into real dollars, so it compares 1:1 with list prices. For DeepSeek the lower off-peak list price is used.

How to spend less

  • Use prompt caching for long repeated context.
  • Cap max_tokens: output tokens cost more than input.
  • Route bulk jobs to the cheap models or the tkbk-cheap alias.
