For Claude Fable 5 (claude_bpe tokenizer), 50,000 words is approximately 66,000 tokens (an average ratio of 1.32 tokens per word in English). Code, technical vocabulary, and non-English scripts will have higher token densities.
Sending 50,000 words as input costs $0.66 (or $0.066 with prompt caching). Generating 50,000 words as output costs $3.30. 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 $0.066). For non-urgent asynchronous batch processing, 24-hour batch queues provide a flat 50% discount across all tokens (costing $0.33 for input, $1.65 for output).
At an average human reading speed of 250 words per minute, 50,000 words takes approximately 200 minutes to read. In contrast, Claude Fable 5 can process or generate this text in seconds.
