Processing or generating 2,500 words (approximately 3,333 tokens) with GLM-5.3-Flash (Z.ai) ranges from $0.000050 (cached input) to $0.000833 (full generation).
Quick answer
For 2,500 words, GLM-5.3-Flash (Z.ai) processes approximately 3,333 tokens. That costs $0.00025 as uncached input, $0.000050 with the modeled cache discount, or $0.000833 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 2,500 words as prompt context, documentation, or background knowledge.

For GLM-5.3-Flash (Z.ai) (other tokenizer), 2,500 words is approximately 3,333 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 2,500 words as input costs $0.00025 (or $0.000050 with prompt caching). Generating 2,500 words as output costs $0.000833. 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 $0.000050). For non-urgent asynchronous batch processing, 24-hour batch queues provide a flat 50% discount across all tokens (costing $0.000125 for input, $0.000417 for output).
At an average human reading speed of 250 words per minute, 2,500 words takes approximately 10 minutes to read. In contrast, GLM-5.3-Flash (Z.ai) can process or generate this text in seconds.
