DeepSeek V4.1 Flash (Max) Token Counter & Cost Calculator
Count tokens for DeepSeek V4.1 Flash (Max) and estimate the exact API cost — $0.30
per 1M input tokens, $1.20 per 1M output tokens — using a real
o200k_base BPE tokenizer. Everything runs in your browser; nothing is uploaded.
DeepSeek V4.1 Flash (Max)
Counts are exact for OpenAI models (o200k_base is GPT-4o/4.1/5's tokenizer). For Claude, Gemini and other vendors — whose tokenizers are not public — treat the count as a close estimate (typically within ±15%).
