已计价 n/m 轮 coverage count so the number is never silently partial.tokens × unit price = amount.registerPriceBook() call rather than a fork.| DeepSeek Harness | 0.1.7-rc.1 — the version this release targets and was tested against |
| Node.js | >=18 (developed and tested on 24.x) |
| pnpm | required by dsh plugin, which is a pnpm passthrough |
The package declares its tested DSH target as a peer dependency, so DSH 0.1.7-rc.1
can perform the compatibility check before installation and at Profile startup.
Other DSH versions are not claimed as compatible. The plugin uses DSH's
conversation.chat.turnTail client slot, the slots / locale client services, and
the Chat turn-usage projection — those are the surfaces to re-check when DSH moves.
dsh plugin --profile web add @jackguo0310/dsh-cost
dsh web
That is the whole install. dsh plugin installs the package into
$DSH_HOME/profiles/web and registers it as a profile bundle automatically — you do
not need to edit the profile's package.json or cordis.patch.yml by hand.
Already running dsh web? Restart it once after installing, then refresh the page.
No npm account or registry involved — useful while a release is not published yet:
dsh plugin --profile web add github:JackGuo0310/dsh-cost
dsh web
The package builds nothing on install (the client half is a prebuilt bundle), so
pnpm runs no prepare script and asks for no build approval.
dsh plugin --profile web update @jackguo0310/dsh-cost
The dependency is keyed by package name either way, so the same command updates a GitHub install too.
dsh plugin --profile web remove @jackguo0310/dsh-cost
Removal also drops the bundle from the profile's dsh.profile.bundles, so the
plugin leaves no trace in the profile.
The cost pill sits under each reply, directly above DSH's own token/time pills.
本轮 ¥x — this turn's cost. A ≈ prefix means the figure is an estimate: the
model is not in the price list, or the turn was served by more than one model.累计 ¥y — the running total for the session.缓存 z% — share of prompt tokens served from cache.Click it for the breakdown: turn total, model, billing window (peak / off-peak),
each bucket's tokens × rate, the session total, 已计价 n/m 轮, and the price
list version.
A turn is shown as 未计价 rather than guessed when no registered price list owns
the provider.
Mirrored from DeepSeek's official 模型 & 价格 page (2026-09-10), in CNY per million tokens:
| Billing item | deepseek-flash off-peak | deepseek-flash peak | deepseek-v4-pro off-peak | deepseek-v4-pro peak |
|---|---|---|---|---|
| Input, cache hit | 0.02 | 0.04 | 0.15 | 0.30 |
| Input, cache miss | 1 | 2 | 4.5 | 9.0 |
| Output | 4 | 8 | 13.5 | 27.0 |
| Cache write | free | free | free | free |
Peak is Beijing time, Monday to Friday (excluding Chinese statutory holidays), 09:00–12:00 and 14:00–18:00. Everything else — including all weekend and holiday hours — is off-peak, at half the peak rate.
A turn costs tokens ÷ 1,000,000 × rate, summed over the four buckets. DeepSeek
does not bill disk-cache writes, so that rate is 0.
Both live in client/client.js, in the DEEPSEEK_BOOK data
structure. Chinese statutory holidays cannot be derived from a clock, so they are a
list; the 2026 mainland-China dates ship as the default. Each January, replace
them with the new State Council notice:
setDeepSeekHolidays(["2027-01-01", "2027-02-05"]); // Beijing time, YYYY-MM-DD
A missing holiday entry can only over-estimate a weekday, never under-estimate it. Weekends are detected automatically.
Nothing in the cost math is DeepSeek-specific: it only reads a price book's
match / models / bucketAt / currency. Register a new one:
registerPriceBook({
id: "my-provider",
label: "My Provider",
currency: "USD",
updated: "2026-09-01",
source: "https://example.com/pricing",
match: (route) => route.provider === "my-provider",
bucketAt: () => "standard", // one flat bucket, or any function of the request time
fallbackModelId: "my-small",
models: [
{
id: "my-small",
label: "My Small",
names: ["my-small", "my-small-2026"],
rates: {
standard: { cacheHit: 0.05, cacheMiss: 0.5, cacheWrite: 0.6, output: 1.5 },
},
},
],
});
git clone https://github.com/JackGuo0310/dsh-cost.git
cd dsh-cost
npm install
dsh plugin --profile web add .
dsh web
npm run check syntax-checks the bundle and the host half; npm test runs the
suite. Both run automatically before npm publish via prepublishOnly.
The browser half is a prebuilt bundle that is also readable source:
client/client.js registers one factory with
window.__ModuleLoader__.load({ id, factory }), and inside the factory only react
and react/jsx-runtime are required — both supplied by DSH's client module system.
There is no build step and no runtime dependency. (react and
react-test-renderer are devDependencies used by the tests only.)
Tests cover the price logic, the peak/off-peak boundary, the registration surface, and real React rendering of the pill and the breakdown panel, with guards that no render emits a React warning and no call site asks for a missing locale key.
