How accurate is the Amazon Nova Pro count?
Amazon does not publish a public tokenizer, so this page reports an estimate — accurate to roughly 5–10% on English text and widening on code or mixed Chinese-English prompts. Treat it as a budgeting number, not an invoice number. If you need invoice-grade counts, count with the exact OpenAI tokenizer on the main calculator and read the gap as your margin of safety.
## What fits in the Amazon Nova Pro context window Amazon Nova Pro accepts **300K tokens**. At roughly 1.3 tokens per English word that is about **230,769 words**, or roughly **1,080,000 characters** of prose. Code and CJK text consume the budget faster: a source file or a Chinese document of the same visible length can run 30–60% more tokens, so leave headroom rather than budgeting to the exact ceiling.Amazon Nova Pro pricing against the rest of Amazon
