For DeepSeek V4 Flash (deepseek_bpe tokenizer), 25,000 words is approximately 33,325 tokens (an average ratio of 1.33 tokens per word in English). Code, technical vocabulary, and non-English scripts will have higher token densities.
Sending 25,000 words as input costs $0.0147 (or $0.000467 with prompt caching). Generating 25,000 words as output costs $0.044. Output tokens are more expensive because autoregressive token generation requires significantly more computation per token.
Yes! If your input text is part of a repeated context, prompt caching saves 50% to 90% (costing $0.000467). For non-urgent asynchronous batch processing, 24-hour batch queues provide a flat 50% discount across all tokens (costing $0.007332 for input, $0.022 for output).
At an average human reading speed of 250 words per minute, 25,000 words takes approximately 100 minutes to read. In contrast, DeepSeek V4 Flash can process or generate this text in seconds.
