The short answer
Counts vary by language and tokenizer. Character counts cannot reliably determine token usage or cost.
Try it in three steps
- Prepare a Chinese passage and a passage with numbers and punctuation.
- Check actual counts using the product's official counter or usage report.
- Distinguish input, output and any other billed categories.
A practice prompt
Before you start
Understand the unit first, then inspect a product's actual counter if available. A counter is not required for the conceptual exercise.
Practice material (fictional)
Compare 你好, hello and SKU-001. Explain why character counts and token counts need not match. Do not ask chat to guess exact counts.Replace placeholders in the prompt with this material, or append the material if there are no placeholders. Reading time excludes doing the exercise.
Explain tokens versus character counts without a fixed conversion. Do not estimate my bill without actual usage data.What to look for (not a recorded test result)
Tokens are not characters. Exact counts require a specified tokenizer; billing also needs rates and actual input/output usage.
If it goes wrong
Treat online conversion rules as rough illustrations; budget from measured usage and current rates.
Check your result
You can identify missing billing inputs rather than multiplying character count by a guessed rate.
