Due to Byte-Pair Encoding (BPE) character splits, Russian text generates 1.7× more tokens than equivalent English text. 1,000 Russian words consume ~2,266 tokens in DeepSeek V4 Flash Vision Exp.
Quick answer
For 1,000 Russian words, DeepSeek V4 Flash Vision Exp is modeled at 2,266 tokens—1.7× the English baseline. That is approximately $0.000997 as input, before any cache discount.
Method & trust
The language page applies the published language multiplier to a 1,333-token English baseline, then applies the model's input/output rates. Tokenizers differ, so benchmark representative text before production budgeting.
Relative to English baseline (1.0×).

Each Cyrillic character requires more token memory than standard ASCII Latin letters.
Use large-vocabulary frontier models to reduce Cyrillic token fragmentation.
Most LLM tokenizers are primarily trained on English-heavy web datasets. Non-Latin characters in Russian (Cyrillic) split across multiple Byte-Pair Encoding (BPE) sub-word or multi-byte UTF-8 tokens, requiring approximately 1.7× more tokens to encode the exact same semantic meaning as English.
Use large-vocabulary frontier models to reduce Cyrillic token fragmentation. In addition, enabling prompt caching on static Russian instructions or documentation saves 75–90% on input token rates.
Yes. DeepSeek V4 Flash Vision Exp has strong multilingual comprehension and generation capabilities in Russian (Русский). The difference is purely computational and financial due to sub-word token splits.
