Processing or generating 500 words (approximately 667 tokens) with DeepSeek V4 Flash ranges from $0.0000093 (cached input) to $0.00088 (full generation).
Quick answer
For 500 words, DeepSeek V4 Flash processes approximately 667 tokens. That costs $0.000293 as uncached input, $0.0000093 with the modeled cache discount, or $0.00088 when generated as output.
Method & trust
The estimate converts the selected English word count with the model tokenizer family, then applies the published input/output price per million tokens. Real prompts vary with code, formatting, language, and system instructions.
You send 500 words as prompt context, documentation, or background knowledge.
DeepSeek V4 Flash drafts a complete 500 words article, chapter, or code module.
400 words input prompt + 100 words output reply.

For DeepSeek V4 Flash (deepseek_bpe tokenizer), 500 words is approximately 667 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 500 words as input costs $0.000293 (or $0.0000093 with prompt caching). Generating 500 words as output costs $0.00088. 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 $0.0000093). For non-urgent asynchronous batch processing, 24-hour batch queues provide a flat 50% discount across all tokens (costing $0.000147 for input, $0.00044 for output).
At an average human reading speed of 250 words per minute, 500 words takes approximately 2 minutes to read. In contrast, DeepSeek V4 Flash can process or generate this text in seconds.
