+# Wan 3.0 pricing and September 23 promotion
+
+Last verified: **2026-09-18**. Recheck after **2026-09-23** (starting September 24).
+
+The code and tests intentionally use the promotional Wan 3.0 rates below.
+Prices stay at these values until a reviewed code change; there is no automatic
+date-based switch. Kinovi advertises 30% off until September 23 without specifying
+the cutoff time or timezone. Confirm the live prices when updating.
+[Kinovi promotion and pricing](https://kinovi.ai/models/wan3-text-to-video)
+
+## Rates currently used
+
+All values are **Kinovi credits per output second**. Each family's rates apply
+to text-to-video, image-to-video, and reference-to-video. Reference media does
+not add billed input seconds. Sources for regular Wan:
+[text](https://kinovi.ai/models/wan3-text-to-video),
+[image](https://kinovi.ai/models/wan3-image-to-video),
+[reference](https://kinovi.ai/models/wan3-ref-to-video).
+
+| Family        | Resolution | Credits/second | Current status                 |
+|---------------|------------|----------------|--------------------------------|
+| Wan 3.0       | 480p       | 9.98           | Promotional until Sep 23       |
+| Wan 3.0       | 720p       | 19.96          | Promotional until Sep 23       |
+| Wan 3.0       | 1080p      | 39.91          | Promotional until Sep 23       |
+| Wan 3.0 Prime | 480p       | 18.86          | No advertised Sep 23 promotion |
+| Wan 3.0 Prime | 720p       | 38.83          | No advertised Sep 23 promotion |
+| Wan 3.0 Prime | 1080p      | 77.66          | No advertised Sep 23 promotion |
+
+Prime sources:
+[text](https://kinovi.ai/models/wan3-prime-text-to-video),
+[image](https://kinovi.ai/models/wan3-prime-image-to-video),
+[reference](https://kinovi.ai/models/wan3-prime-ref-to-video).
+Prime 480p for 30 seconds is **565.8 credits**; the original supplied reference
+example's 568.8 was a typo. Recheck Prime independently; the regular Wan
+promotion ending does not establish a Prime price change.
+
+The promotional rates already include the discount. Total credits are the
+selected rate multiplied by output seconds. Both pricing tiers currently use
+the same credit rates; only their credit purchase rates differ. The client uses
+192.98 credits/USD for Consumer and 243.16 for Enterprise, defined in
+[pricing constants](src/pricing/constants.rs).
+[KinoviPricingTier::cost_from_credits](src/pricing/kinovi_pricing_tier.rs) rounds
+the total to hundredths of a credit and calculates fractional, floor, and ceiling
+USD cents. Use those purchase rates for client costs; Kinovi's displayed USD
+prices use a different conversion.
+
+## Advertised non-promotional rates to recheck
+
+These are the crossed-out prices shown alongside the promotion on September 18.
+They are **reference values for the later update**, not active calculator rates
+or a guarantee of what Kinovi will charge after the promotion.
+The same values appear on the regular Wan
+[text](https://kinovi.ai/models/wan3-text-to-video),
+[image](https://kinovi.ai/models/wan3-image-to-video), and
+[reference](https://kinovi.ai/models/wan3-ref-to-video) pricing pages.
+
+| Resolution | Current promotional credits/second | Advertised non-promotional credits/second |
+|------------|------------------------------------|-------------------------------------------|
+| 480p       | 9.98                               | 14.2571                                   |
+| 720p       | 19.96                              | 28.5143                                   |
+| 1080p      | 39.91                              | 57.0143                                   |
+
+## How to update after September 23
+
+1. Reopen the six model pages above and confirm the promotion ended, the exact
+   credit rates, and total-credit rounding. Check consumer quotes for multiple
+   durations and every resolution; the web client uses the consumer workflow.
+   Record the verification date and evidence in this document.
+2. Update `WAN_CREDIT_HUNDREDTHS_PER_SECOND` and `Wan3p0Model::calculate_costs`
+   in [wan_3p0.rs](src/generate/video/wan_3p0.rs). The current table is
+   `[998, 1996, 3991]` in 480p/720p/1080p order. **The advertised replacement
+   rates have four decimal places:** the existing hundredths representation
+   cannot preserve them. If confirmed, use a sufficient fixed-point scale
+   (for example 10,000), rename the constants to match their units, and adjust
+   the final divisor. Preserve rate precision until after multiplying by
+   duration; verify provider rounding before changing the shared credit
+   conversion. If both families change scale, rescale the Prime integers while
+   preserving Prime's monetary rates unless a separate price change is confirmed.
+3. Update the literal expectations in
+   [wan_3p0_tests.rs](src/generate/video/wan_3p0_tests.rs): `WAN_CREDITS`,
+   `WAN_CENTS`, the `199.6` regular `reference_media_tests!` argument (720p/10s),
+   and the `99.8` regular image `check!` argument (720p/5s). The default-price
+   and seed/audio tests already read the literal tables. Keep expected prices
+   independent of production rate constants and assert both pricing tiers.
+   Update Prime expectations only if its verified monetary rates change.
+4. Update this document and the dated comments beside the production constants
+   and test tables. Keep the promotional snapshot as historical context.
+5. Run from the repository root:
+
+   ```sh
+   cargo test --offline -p kinovi_web_client --lib wan_3p0_tests
+   cargo test --offline -p kinovi_web_client --lib
+   ```
+
+   The Wan HTTP tests use a local server and need permission to bind localhost.
+   These commands leave the existing ignored live-generation tests ignored.

+//! Shared options and wire format for Wan 3.0 and Wan 3.0 Prime.
+//!
+//! Schema: https://kinovi.ai/models/wan3-ref-to-video (checked 2026-09-18).
+//! All modes bill only OUTPUT seconds; reference media does not add a surcharge.
+//!
+//! Output accepts any whole-second duration from 2 through 30. Reference
+//! videos must each be 1-15s and total at most 15s; their total plus output
+//! duration must not exceed 30s. Thus 10s of video references allows at most
+//! 20s of output. Audio and image references do not consume this video budget.
+//! The optional measured reference duration enables local validation; otherwise
+//! Kinovi checks actual file durations. This client does not probe media URLs.
+//!
+//! Pricing sources (all three modalities share each family's rates):
+//! - https://kinovi.ai/models/wan3-text-to-video
+//! - https://kinovi.ai/models/wan3-prime-ref-to-video
+//! Pricing maintenance and the September 23 promotion: `costs_wan_3p0.md`
