Processing or generating 1,000,000 words (approximately 1,333,000 tokens) with Text Embedding 3 (Large) ranges from $0.0433 (cached input) to $0.00 (full generation).
You send 1,000,000 words as prompt context, documentation, or background knowledge.
Text Embedding 3 (Large) drafts a complete 1,000,000 words article, chapter, or code module.
800,000 words input prompt + 200,000 words output reply.

For Text Embedding 3 (Large) (cl100k_base 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 $0.1733 (or $0.0433 with prompt caching). Generating 1,000,000 words as output costs $0.00. 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 $0.0433). For non-urgent asynchronous batch processing, 24-hour batch queues provide a flat 50% discount across all tokens (costing $0.0866 for input, $0.00 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, Text Embedding 3 (Large) can process or generate this text in seconds.
