dsh-model-billing 是一个 DSH Web 客户端插件。它可以接管输入框右下角的模型选择器，让你按自己的顺序排列模型，并为每个模型维护三档 token 价格；会话过程中按实际 usage 估算每一轮和整个会话的费用。

功能

• 自定义模型顺序：在“设置 → 模型与费用”中用 ↑ / ↓ 调整已配置模型的顺序。模型选择器按这个顺序展示，跨提供方也保持你排的顺序，并用提供方名称分组。
• 三档 token 价格：每个模型可填写每百万 tokens 的缓存命中输入、缓存未命中输入、输出价格。0 是有效价格，留空表示未设置。
• DeepSeek 官方价内置：deepseek-flash 和 deepseek-v4-pro 默认使用 DeepSeek 官网的峰谷价，并在设置页标明“官方价”；填入完整的三档自定义价即可覆盖官方价，标为“自定义”。
• 逐轮费用与使用模型：每轮结束后在轮尾显示这一轮使用的模型，以及该轮费用和缓存命中率。
• 可配置轮尾：在设置中总开关轮尾显示，并可分别开关使用模型、模型提供商、费用、token、缓存命中率、文字标签，调整字号、间距和字重；也可以关闭选择器接管，恢复 DSH 内置模型选择器。输入框下方的费用估算另有独立开关。
• 本会话费用：输入框下方显示本会话累计估算、最近一轮费用和缓存命中率；展开后可查看按轮次和按模型的明细。
• 历史价格与未定价路由：设置页的“历史价格”区可以为已移出配置的模型补价、改价或删除，不必把模型加回列表；从模型列表删除模型不会删除它的价格，历史调用仍按保存的价格计算，查不到名称时显示原始模型 id。缺价时显示统一提示，可在设置里关闭这条提示。
• DeepSeek 也计入金额：每条 usage 按事件发生时的北京时间自动选择高峰或空闲价，与第三方模型一起进入统计。

估算口径

缓存命中输入 × 命中价
+（未缓存输入 + 缓存写入）× 未命中价
+ 输出 × 输出价

价格单位是“元 / 百万 tokens”。缓存写入按缓存未命中价计算，这是三档价格模型下的近似处理。金额来自会话日志中的 provider usage，实际账单以 provider 为准。

DeepSeek 官方价

以下价格内置在 host.js 的 DEEPSEEK_PRICES 中，单位“元 / 百万 tokens”。来源：DeepSeek 模型 & 价格（查询于 2026-10-19）。

模型	时段	缓存命中	缓存未命中	输出
deepseek-flash	高峰	0.04	2	8
deepseek-flash	空闲	0.02	1	4
deepseek-v4-pro	高峰	0.30	9	27
deepseek-v4-pro	空闲	0.15	4.5	13.5

高峰时段为北京时间周一至周五 9:00–12:00、14:00–18:00（中国法定节假日除外）；其余时间、周末和法定节假日全天为空闲时段。空闲价是高峰价的一半。

DeepSeek 价格默认只读展示；如需按其他渠道或折扣价计费，可在设置页点“自定义价格”填入完整三档价格，保存后以自定义价为准并标为“自定义”；三项清空后保存即可恢复官方价。官网调价或节假日安排变化后，需要更新 host.js 中的 DEEPSEEK_PRICES 和 DEEPSEEK_HOLIDAYS；目前内置的是 2026 年节假日。

其他模型价格

插件不预置第三方模型价格。首次使用时，在“设置 → 模型与费用”中按 provider 的官方价填写三档价格即可；未填完整价格的模型不会产生金额，界面会标记“未定价”或“部分未定价”。

不同平台的缓存折扣、上下文阶梯价和活动价差异较大，建议直接使用你的实际结算价。插件不做自动抓取，也不猜测默认价。

安装

需要 DSH ^0.2.1-rc.3。

npm

dsh plugin --profile desktop add dsh-model-billing

从 dsh-market 安装

在 dsh-market 中搜索 dsh-model-billing 安装。

从 GitHub Release 手动安装

1. 从 Releases 下载 dsh-model-billing.tgz。
2. 执行：

dsh plugin --profile desktop add ./dsh-model-billing.tgz

把 desktop 换成你实际使用的 profile。

从源码安装

git clone https://github.com/likaileave/dsh-model-billing.git
dsh plugin --profile desktop add ./dsh-model-billing

安装或更新后刷新 Web 页面。设置页位于“模型与费用”。

发布

npm 包和 GitHub Release 使用相同版本号，两个渠道分别发布：

• npm：https://www.npmjs.com/package/dsh-model-billing
• GitHub Releases：https://github.com/likaileave/dsh-model-billing/releases

两个渠道是并列的发布渠道，不承诺自动同步。

数据位置

模型顺序和价格保存在：

~/.dsh/model-billing.json

若设置了 DSH_HOME，则为 $DSH_HOME/model-billing.json。保存时先写临时文件再原子替换；文件损坏时回退为空配置，不会在未保存的情况下覆盖原文件。

已知限制

• DeepSeek 官方峰谷价只对 deepseek 开头的官方 provider（如 deepseek-account）且模型名在官方价表内时生效；openrouter、my-deepseek-relay 这类第三方即使模型名含 deepseek 也按普通规则计费，可自行填价。
• 显示设置（轮尾开关、字号、间距、是否接管选择器等）只保存在 Host 的 model-billing.json 里，不再镜像到浏览器 localStorage，因此换设备或换浏览器不会不同步；旧版本写入的 localStorage 键会被自动清除。
• 除本机回环地址（127.0.0.1 / localhost / [::1]）外，Host 头与该连接实际监听的地址（socket.localAddress + localPort）一致时也会放行，因此 --host 0.0.0.0 后用局域网 IP 访问可用；反向代理若改写了 Host，需要让它保留原 Host 或与实际监听地址一致，否则四个路由返回 403，此时模型选择器回退为 DSH 内置版本（费用与排序功能不可用），不会影响正常聊天。
• 模型选择器由本插件接管，依赖 ctx.modelDirectories。该服务不可用或 catalog 尚未加载完成时，插件不会强行覆盖内置选择器，价格和费用统计不受影响。
• /model 命令仍由 DSH 自带实现，顺序不保证与右下角选择器一致。
• 一轮里的多次模型尝试（重试、失败等）会分别计入；失败调用如果 provider 没有返回 usage，则无法计入。
• 只统计当前载入 Host 的会话；未打开的历史会话在进入后按需计算。
• provider 返回的 totalTokens 与三档明细不一致时，保留三档明细并把该轮标为“部分未定价/不完整”，不再整条丢弃，避免大幅少报。
• 第三方价格是静态配置，不会自动跟随官网调价；内置节假日表目前只覆盖 2026 年，2027 年起需更新 DEEPSEEK_HOLIDAYS。

开发

node --check host.js
node --check client.js
node --test test/*.test.mjs

当前 25 个测试通过。插件没有运行时 npm 依赖。

dsh-model-billing is a DSH Web GUI plugin that can take over the composer's model picker, lets you order configured models yourself, stores three per-million-token prices per model, and estimates per-turn and session cost from provider usage.

Features

• Custom model order in Settings → Models & Cost; the composer picker follows that order across providers and groups models by provider.
• Three prices per model: cache-hit input, cache-miss input, and output, in CNY per million tokens. 0 is a valid price; blank means unset.
• Built-in official DeepSeek pricing for deepseek-flash and deepseek-v4-pro, selected per usage event between peak and off-peak Beijing time. A complete set of custom prices overrides the table and is labelled "Custom".
• Per-turn model and amount at the end of each turn, together with the turn's cache-hit rate.
• Configurable turn tail: a master switch for the turn tail, plus individual toggles for models, provider names, cost, tokens, cache-hit rate, and text labels; adjust font size, spacing, and weight; or disable the picker takeover to restore the built-in DSH picker. The composer cost estimate has its own switch.
• Session summary below the composer plus a detail panel grouped by turn and by model.
• Historical prices and unpriced routes: the "Historical prices" section in Settings lets you add, edit, or remove prices for models no longer in your order without re-adding them. Removing a model from the list keeps its price, so historical calls still bill correctly; when the name is unknown, the raw model id is shown. Unpriced calls share one notice that can be switched off.
• DeepSeek is billed too, using the same three-price formula and the event's timestamp.

Cost formula

cache-hit input × hit price
+ (uncached input + cache write) × miss price
+ output × output price

Prices are CNY per million tokens. Cache writes are approximated at the cache-miss price. Figures come from provider usage in the session log; the provider's invoice is authoritative.

The plugin ships no third-party price defaults. Enter your provider's actual rates in Settings → Models & Cost. Models without a complete three-price set are marked as unpriced and contribute no amount. DeepSeek prices come from the built-in official table; enter a complete custom set to override it, or clear all three fields to restore the official rates.

Install

Requires DSH ^0.2.1-rc.3.

npm

dsh plugin --profile desktop add dsh-model-billing

From dsh-market

Search for dsh-model-billing in dsh-market.

From a GitHub Release

Download dsh-model-billing.tgz from Releases, then:

dsh plugin --profile desktop add ./dsh-model-billing.tgz

From a checkout

git clone https://github.com/likaileave/dsh-model-billing.git
dsh plugin --profile desktop add ./dsh-model-billing

Refresh the Web page after installing or updating.

Release channels

The npm package and the GitHub Release use the same version number and are published separately:

• npm: https://www.npmjs.com/package/dsh-model-billing
• GitHub Releases: https://github.com/likaileave/dsh-model-billing/releases

They are parallel distribution channels, not an automatic mirror.

Data

Order and prices live in ~/.dsh/model-billing.json (or $DSH_HOME/model-billing.json). Writes use a temporary file plus atomic replace.

Limitations

• Official DeepSeek peak/off-peak rates apply only to providers whose id starts with deepseek (such as deepseek-account) and to models present in the official table. A third-party route such as openrouter or my-deepseek-relay is billed by the normal rules even when the model name contains deepseek, and you can price it yourself.
• Display settings (turn-tail switches, font size, spacing, picker takeover) are stored only in the Host's model-billing.json; they are no longer mirrored into browser localStorage, so they do not sync across devices or browsers. Any key written by older builds is cleared automatically.
• Besides loopback (127.0.0.1, localhost, [::1]), a request is accepted when its Host header matches the address this socket actually listens on (socket.localAddress + localPort), so a LAN IP works with --host 0.0.0.0. A reverse proxy that rewrites Host must preserve it or match the listening address, otherwise the four routes return 403 and the picker falls back to the DSH built-in one; chat itself keeps working.
• The custom picker depends on ctx.modelDirectories; when that service is unavailable or the catalog has not loaded yet, the plugin leaves the built-in picker alone.
• The /model command is still implemented by DSH and may not follow the custom order.
• Multiple attempts within a turn are counted separately; failed calls without provider usage cannot be counted.
• Only sessions loaded by the current Host are counted.
• When a provider's totalTokens disagrees with its three buckets, the buckets are kept and the turn is marked partial instead of being dropped, which avoids large under-reporting.
• Third-party prices are static and are not refreshed automatically. The bundled holiday table covers 2026 only; update DEEPSEEK_HOLIDAYS for 2027 onward.

Development

node --check host.js
node --check client.js
node --test test/*.test.mjs

25 tests currently pass. The plugin has no runtime npm dependencies.
