How accurate is the Gemini 3.1 Flash-Lite count?
Google 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.

At roughly 1.3 tokens per English word that is about **769,230 words**, or roughly **3,600,000 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.Gemini 3.1 Flash-Lite pricing against the rest of Google
