DeepSeek R1 0528 (May '25) Token Counter & Cost Calculator
Count tokens for DeepSeek R1 0528 (May '25) and estimate the exact API cost — $1.35
per 1M input tokens, $3.00 per 1M output tokens — using a real
o200k_base BPE tokenizer. Everything runs in your browser; nothing is uploaded.
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%).
