Processing or generating 1,000,000 words (approximately 1,333,000 tokens) with Kimi K3 (Moonshot) ranges from $0.3999 (cached input) to $19.995 (full generation).
Quick answer
For 1,000,000 words, Kimi K3 (Moonshot) processes approximately 1,333,000 tokens. That costs $3.999 as uncached input, $0.3999 with the modeled cache discount, or $19.995 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 1,000,000 words as prompt context, documentation, or background knowledge.

For Kimi K3 (Moonshot) (kimi_bpe tokenizer), 1,000,000 words is approximately 1,333,000 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 1,000,000 words as input costs $3.999 (or $0.3999 with prompt caching). Generating 1,000,000 words as output costs $19.995. 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 $0.3999). For non-urgent asynchronous batch processing, 24-hour batch queues provide a flat 50% discount across all tokens (costing $1.999 for input, $9.998 for output).
At an average human reading speed of 250 words per minute, 1,000,000 words takes approximately 4000 minutes to read. In contrast, Kimi K3 (Moonshot) can process or generate this text in seconds.
