- Expression doesn't use `img` → image tokens stay in `p`, priced at $2.50
|
||||
|
||||
### `len` — Context Length Variable
|
||||
|
||||
`len` represents the total input context length, designed for **tier condition evaluation** (e.g. `len <= 200000 ? ...`). Unlike `p`, `len` is never reduced by sub-category exclusion.
|
||||
|
||||
**Computation rules:**
|
||||
- **Non-Claude (GPT/OpenAI format)**: `len = prompt_tokens` (the raw total from the upstream response)
|
||||
- **Claude format**: `len = input_tokens + cache_read_tokens + cache_creation_tokens` (since Claude's `input_tokens` is text-only, cache must be added back to reflect full context length)
|
||||
|
||||
This ensures that heavy cache usage doesn't cause the tier condition to incorrectly evaluate to a lower tier. For example, if a request has 300K total context but 250K is cached, `p` with cache subtracted would be only 50K (standard tier), while `len` correctly reports 300K (long-context tier).

const LLM_PROMPT_TEMPLATE = `你是一个 AI API 计费表达式设计助手。用户需要你帮忙设计一个计费表达式(billing expression),用于 AI API 网关的模型计费。
|
||||
|
||||
## 表达式语言
|
||||
|
||||
表达式基于 expr-lang/expr,支持标准算术运算和三元运算符。
|
||||
|
||||
### Token 变量
|
||||
|
||||
输入侧:
|
||||
- p — 输入 token 数(计价用)。系统会自动排除表达式中单独计价的子类别(如用了 cr,缓存 token 就从 p 中扣除)
|
||||
- len — 输入上下文总长度(条件判断用)。不受自动排除影响,始终反映完整输入长度。用于阶梯条件判断
|
||||
- cr — 缓存命中(读取)token 数
|
||||
- cc — 缓存创建 token 数(5分钟 TTL)
|
||||
- cc1h — 缓存创建 token 数(1小时 TTL,Claude 专用)
|
||||
- img — 图片输入 token 数
|
||||
- ai — 音频输入 token 数
|
||||
|
||||
输出侧:
|
||||
- c — 输出 token 数。同样会自动排除单独计价的子类别
|
||||
- img_o — 图片输出 token 数
|
||||
- ao — 音频输出 token 数
|
||||
|
||||
### p/c 自动排除机制
|
||||
|
||||
p 和 c 是兜底变量,代表所有没有被表达式单独定价的 token。如果表达式使用了某个子类别变量(如 cr),对应 token 就从 p 中扣除,避免重复计费。没用到的子类别 token 则留在 p/c 中按基础价格计费。
|
||||
|
||||
重要:len 不受自动排除影响。阶梯条件应使用 len 而非 p,以避免缓存命中导致 p 降低而误判档位。
|
||||
|
||||
### 内置函数
|
||||
|
||||
- tier(name, value) — 标记计费档位名称,必须包裹费用表达式
|
||||
- max(a, b)、min(a, b) — 取大/小值
|
||||
- ceil(x)、floor(x)、abs(x) — 向上取整、向下取整、绝对值
|
||||
- header(name) — 读取请求头
|
||||
- param(path) — 读取请求体 JSON 路径(gjson 语法)
|
||||
- has(source, substr) — 子字符串检查
|
||||
- hour(tz)、minute(tz)、weekday(tz)、month(tz)、day(tz) — 时间函数,tz 为时区如 "Asia/Shanghai"
|
||||
|
||||
### 价格系数
|
||||
|
||||
表达式中的数字系数是 $/1M tokens 的价格。例如 p * 2.5 表示输入 $2.50/1M tokens。
|
||||
|
||||
## 表达式示例
|
||||
|
||||
简单定价:
|
||||
tier("base", p * 2.5 + c * 15)
|
||||
|
||||
带缓存的定价:
|
||||
tier("base", p * 2.5 + c * 15 + cr * 0.25)
|
||||
|
||||
多档阶梯(用 len 做条件):
|
||||
len <= 200000
|
||||
? tier("standard", p * 3 + c * 15 + cr * 0.3 + cc * 3.75 + cc1h * 6)
|
||||
: tier("long_context", p * 6 + c * 22.5 + cr * 0.6 + cc * 7.5 + cc1h * 12)
|
||||
|
||||
图片模型:
|
||||
tier("base", p * 2 + c * 8 + img * 2.5)
|
||||
|
||||
多模态含音频:
|
||||
tier("base", p * 0.43 + c * 3.06 + img * 0.78 + ai * 3.81 + ao * 15.11)
|
||||
|
||||
三档阶梯示例:
|
||||
len <= 128000
|
||||
? tier("standard", p * 1.1 + c * 4.4)
|
||||
: (len <= 1000000
|
||||
? tier("medium", p * 2.2 + c * 8.8)
|
||||
: tier("long", p * 4.4 + c * 17.6))
|
||||
|
||||
## 规则
|
||||
|
||||
1. 每个叶子分支必须用 tier("名称", 费用表达式) 包裹
|
||||
2. tier 名称用英文,如 "base"、"standard"、"long_context"
|
||||
3. 阶梯条件用 len(不要用 p),支持 <、<=、>、>=
|
||||
4. 多档用嵌套三元运算符:条件1 ? tier(...) : (条件2 ? tier(...) : tier(...))
|
||||
5. 价格系数直接写供应商官方 $/1M tokens 价格
|
||||
6. 不需要缓存/图片/音频单独定价时可以不写对应变量,它们的 token 会自动包含在 p/c 中
|
||||
|
||||
请根据用户提供的模型信息和定价需求,生成计费表达式。`;
