|---|---|---|---|
| GPT-4o | 58 | $2.50 / $10.00 | $0.0001 |
| GPT-4 Turbo | 63 | $10.00 / $30.00 | $0.0006 |

估算方法：中文按 字数×1.5，英文按 词数×1.3，其余字符按 1/4 计算，再按模型比例微调。仅为近似值，实际 token 数以模型 tokenizer 为准。
使用说明
- 在输入框粘贴文本
- 自动估算各大 LLM（GPT / Claude 等）的 token 数量
- 同步显示字符数与单词数参考
- 结果实时更新，便于控制 Prompt 长度
常见问题
- 数据处理安全吗？ 计数全部在浏览器本地完成，不上传文本
- 结果准确吗？ 为估算值，与模型实际 tokenizer 可能有少量偏差
- 中文怎么算？ 中文一般每字 1-2 token，具体以模型分词器为准
补充说明
Token 是 LLM 计费与上下文长度的基本单位，控制 token 数有助于节省成本并避免超出上下文窗口。
