dsh-deepseek-cny-cost
See what the chat you are reading has cost, in CNY, inside the DeepSeek Harness Web GUI.
A small badge sits under the composer next to the session statistics:
≈¥0.0123
- The number is the running total for the chat you are looking at; switching chats switches the number, and it grows as the chat works;
- Hovering (or a screen reader) reveals the breakdown: uncached input, cache-hit input, and output tokens, each with its own cost;
- It renders only while the selected provider is a DeepSeek official route, because third-party relays are not billed at DeepSeek's peak / off-peak rates.
How it prices
It reads two projections the session already exposes and issues no requests of its own:
| Data | Source |
|---|
| Token usage | tokenUsage (uncachedInputTokens, cacheReadTokens, cacheWriteTokens, outputTokens) |
| Current model | modelSelection |
Prices come from the official Models & Pricing page (checked 2026-10), in CNY per million tokens:
| Model | Cache hit | Cache miss | Output |
|---|
deepseek-flash | 0.04 | 2 | 8 |
deepseek-v4-pro | 0.30 | 9 | 27 |
Those are peak rates. Off-peak is half of peak; peak is Beijing time Monday–Friday (excluding Chinese statutory holidays) 09:00–12:00 and 14:00–18:00, and every other hour — weekends and holidays included — is off-peak.
- Cache writes are billed at the cache-miss input rate, matching DeepSeek's rule that there is no separate write fee;
- Legacy names
deepseek-v4-flash and deepseek-v4-flash-vision-exp are priced as Flash, per the official note;
- An unknown model name hides the badge instead of inventing a price.
Known limits
- An estimate, not an invoice. It excludes per-request Search / Fetch charges; the official bill wins.
- Chats that switched models are priced with the currently selected model, because
tokenUsage is a whole-chat total with no per-model split.
- Holidays: the built-in table covers 2026. A year without an entry falls back to weekends only, so its holiday weekdays would be priced as peak.
- Shown for DeepSeek official providers (
deepseek-official, deepseek-account, or any new provider id starting with deepseek).
