# Bei

Kila modeli inagharimu exactly kiasi anachotoza mtengenezaji wa modeli hiyo, kwa dola za Marekani. Unalipa kutoka kwenye **salio lako la API**,
ambalo huhesabiwa kwa **krediti za API**: **salio za API 1,000 = $ 1**. Salio la API ni salio lake lenyewe, tofauti na
krediti za programu za Doitong. Hakuna mipango, kiwango cha chini au ada kwa kila modeli: ombi hugharimu bei yake, inayokatwa kutoka
kwenye salio la API ombi linapokubaliwa.

Nchini Urusi (doitong.ru, api.doitong.ru, au `?currency=rub`) bei pia huonyeshwa kwa ruble: bei ya USD × kiwango cha
USD/RUB × 1.3.

## Vipimo

Kila modeli ina kipimo kimoja cha utozaji, kinachoonyeshwa kwenye ukurasa wake na katika `GET https://api.doitong.com/v1/models/{model_id}`:

| Kipimo | Kiasi |
|---|---|
| `second` | Sekunde za video au sauti ya tokeo (`duration`) |
| `image` | Picha zilizozalishwa (`num_images`) |
| `megapixel` | Upana × urefu wa tokeo, kwa megapikseli (1 MP = 1024 × 1024 pikseli) |
| `video` | Video moja iliyozalishwa |
| `request` | Ombi moja |
| `1000_characters` | Herufi za maandishi ya ingizo, kwa kila 1000 |
| `step` | Hatua za mafunzo |

Bei = kiasi × krediti za API kwa kila kipimo, ikizungushwa juu hadi krediti nzima ya API ($ 0.001), na kamwe si chini ya 1. Vipimo vya bei ya chini sana
vinaweza kuwa na bei ya sehemu kwa kila kipimo (`0.4` krediti za API kwa sekunde); jumla ya ombi pekee ndiyo huzungushwa.

Baadhi ya modeli hutoza kiwango tofauti kulingana na ingizo: video yenye sauti hugharimu zaidi kuliko isiyo na sauti, 4K hugharimu zaidi
kuliko 1K, na kadhalika. **Sheria** hizi zimeorodheshwa kwenye ukurasa wa kila modeli. Kigezo unachoacha nje huhesabiwa kuwa thamani yake ya chaguomsingi,
kwa hiyo bei unayoona ya ingizo ndiyo bei unayolipa.

## Bei kamili, iliyopimwa, iliyokadiriwa na ya matumizi

Kila bei ina `mode`:

- `exact`: bei huhesabiwa kutokana na ingizo lako (sekunde, picha, megapikseli, herufi, hatua, au bei moja ya kudumu
  kwa kila video au ombi).
- `measured`: bei hufuata faili unazotuma: urefu wa video au sauti ya ingizo, ukubwa wa picha ya ingizo, kasi ya fremu au idadi ya fremu ya video. Zana za kuongeza mwonekano,
  ulandanishi wa midomo, video-kwa-video, unukuzi na zana za sauti
  huwekewa bei kwa njia hii. Kabla ya kuendesha, API husoma urefu wa faili, mwonekano na kasi ya fremu (nukuu hufanya
  vivyo hivyo), kwa hiyo nukuu ndiyo hasa utakayotozwa. Ukurasa wa modeli unasema unalipia nini ("Bei kwa sekunde ya
  video yako ya ingizo") na kikokotoo chake hutumia nambari za faili lako. Faili lisiloweza kusomwa hukataliwa kwa
  `unmeasurable_input` na hakuna kinachotozwa.
- `estimate`: gharama ya modeli yenyewe hutegemea kitu ambacho ingizo haliwezi kuonyesha mapema (tokeni, muda wa uchakataji).
  Modeli kama hiyo hutoza **bei iliyokadiriwa kwa kila uendeshaji** (kwa kila picha ya tokeo ikiwa ina idadi ya picha), iliyowekwa kutokana na
  wastani wa gharama za uendeshaji halisi wa modeli hiyo. Bado unajua bei kabla ya kuendesha: nukuu ndiyo unayolipa.
- `metered`: modeli **hutozwa kulingana na matumizi halisi**, ambayo inajulikana na uendeshaji wenyewe pekee: tokeni ambazo modeli ya lugha au
  maono husoma na kuandika, sekunde za usemi ambazo modeli ya sauti huzalisha, au muda wa uchakataji wa modeli.
  Tazama [Hutozwa kulingana na matumizi](#metered) hapa chini.

Kurasa za modeli husema "Bei kwa kila uendeshaji", "Bei kwa sekunde ya video yako ya ingizo" (na zinazofanana), "Bei iliyokadiriwa kwa kila uendeshaji" au
"Hutozwa kulingana na matumizi"; `GET https://api.doitong.com/v1/models?mode=measured`, `?mode=estimate` na `?mode=metered` huziorodhesha.

## Hutozwa kulingana na matumizi

Modeli ya `metered` ina bei ya matumizi ("$0.01 kwa tokeni 1000", "$0.002 kwa sekunde ya sauti iliyozalishwa", "$0.00111 kwa
sekunde ya muda wa uchakataji") na **kiwango cha juu kwa kila uendeshaji**: kiasi cha juu ambacho uendeshaji unaweza kugharimu, kulingana na kile ombi lako linasema
(`max_tokens`, urefu wa maandishi yako, mwonekano, idadi ya matokeo) na mipaka iliyochapishwa ya modeli. Kamwe
hakitegemei maudhui ya faili lililo nyuma ya URL. Kwa modeli inayotozwa kulingana na muda wa uchakataji au urefu wa kipindi cha sauti,
kiwango cha juu ni muda mrefu zaidi ambao ombi linaweza kuendeshwa (dakika 15 kwa picha, 30 kwa sauti, 60 kwa video), kwa hiyo huwa
juu sana kuliko uendeshaji wa kawaida. Ingizo ambalo kiwango chake cha juu kingezidi kikomo cha modeli kwa kila uendeshaji (maandishi marefu sana) hukataliwa
kwa `422 invalid_input`:

1. Nukuu hurudisha kiwango hicho cha juu kama `credits` (pamoja na `hold` na `typical`, uendeshaji wa kawaida). Uendeshaji unapoanza,
   kiwango cha juu hukatwa kutoka kwenye salio la API, na ndicho ambacho salio na bajeti ya ufunguo wako lazima viweze kugharamia.
2. Uendeshaji unapofaulu, ombi hutatuliwa kulingana na matumizi ambayo modeli inaripoti: matumizi × bei ya matumizi,
   ikizungushwa juu hadi krediti nzima ya API. **Sehemu iliyobaki ya kiwango cha juu hurejeshwa kiotomatiki**, mara moja, kama safu ya `refund`
   kwenye salio lako la API.
3. Uendeshaji kamwe hauzidi kugharimu kiwango chake cha juu, hata kama matumizi yake yangekuwa makubwa. Uendeshaji ulioshindwa au ulioghairiwa hurejeshewa fedha kikamilifu, kama
   kawaida.

Uendeshaji mwingi hugharimu chini sana ya kiwango cha juu; ukurasa wa modeli huonyesha "Hadi $X kwa kila uendeshaji" kwa ingizo la mjenzi na
uendeshaji wa kawaida ("from" kwenye katalogi). Kwa modeli chache zinazotozwa kulingana na muda wa uchakataji, matumizi ni muda wa uchakataji wa modeli (uliowekwa alama
`approximate`).

```json 200 OK · nukuu ya modeli ya metered
{
  "object": "quote",
  "credits": 621,
  "usd": "0.621",
  "mode": "metered",

  "settlement": "usage",
  "display": "$0.01 / 1000 tokens",
  "breakdown": "up to 62.035 × 1000 tokens × $0.01"
}
```

Baada ya uendeshaji, `cost` ya ombi huonyesha kilichoshikiliwa na matumizi yaliyofikia:

```json
{
  "cost": { "credits": 621, "usd": "0.621", "charged": 621, "refunded": 611, "mode": "metered", "held": 621,
            "typical": 10, "settled": { "status": "settled", "credits": 10, "usd": "0.01", "quantity": 1,
            "unit": "1000_tokens", "unit_usd": "0.01", "source": "billed_usage", "approximate": false } }
}
```

`charged − refunded` ndiyo gharama ya uendeshaji. `settled.status` ni `pending` kwa muda kati ya matokeo na
utatuzi, na `no_usage` katika hali nadra ambayo modeli haikuripoti matumizi yoyote (hapo kiwango cha juu hubaki kuwa bei).

## Nukuu kabla ya kuendesha

`POST https://api.doitong.com/v1/quote/{model_id}` hupokea mwili uleule ambao ungetuma kwa `run` na kurudisha bei ya
ingizo hilo: bei kamili, isipokuwa kwa modeli [inayotozwa kulingana na matumizi](#metered), ambapo ni kiwango cha juu ambacho uendeshaji unaweza kugharimu. Haihitaji ufunguo na haina gharama:

```bash
curl -X POST "https://api.doitong.com/v1/quote/flux/schnell" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "A lighthouse at dusk", "num_images": 2}'
```

```json 200 OK · nukuu

  "breakdown": "2 MP (2 images) × 3 API credits",
  "input": { "prompt": "A lighthouse at dusk", "num_images": 2 },
  "warnings": []
}
```

Ukiwa na ufunguo, nukuu pia hurudisha `balance_credits` na `balance_usd` (salio lako la API), `affordable` na
`key_budget_remaining`. Ongeza `?currency=rub` kwa kiasi cha `rub`.

> [!TIP]
> **Nukuu ndiyo tozo.** Chaguo la kukokotoa lilelile huhesabu vyote viwili, kwa hiyo uendeshaji wenye ingizo hili hugharimu hasa `credits`.
> Isipokuwa pekee ni modeli [inayotozwa kulingana na matumizi](#metered) (`mode: metered`): hapo `credits` ni kiwango cha juu ambacho uendeshaji unaweza
> kugharimu, hukatwa unapoanza, na sehemu isiyotumika hurejeshwa baada ya uendeshaji.

## Vitu vya bei

Kila bei katika API ina muundo uleule:

- models: `price: { "credits": 112, "usd": "0.112", "unit": "second", "display": "$0.112 / second",
  "credits_display": "112 API credits / second", "from_credits": 560, "from_usd": "0.56", "mode": "exact" }` — pamoja na `rub`,
  `rub_display` na `from_rub` nchini Urusi au kwa `?currency=rub`;
- requests: `cost: { "credits": 560, "usd": "0.56", "charged": 560, "refunded": 0 }` (krediti za API; ombi la `metered`
  huongeza `mode`, `held`, `typical` na `settled`, tazama [Hutozwa kulingana na matumizi](#metered));
- account: `GET https://api.doitong.com/v1/account` hurudisha `credits` (salio la API), `balance: { "credits", "usd" }` na
  `storage` (bei ya hifadhi ya faili, matumizi na makadirio ya kila mwezi).

## Marejesho ya fedha

- Ombi batili (yoyote ya `4xx` kabla ya uendeshaji kuanza) halitozwi kamwe.
- Ombi linalomalizika kwa `failed` (pamoja na `timeout`) hurejeshewa fedha kikamilifu kwenye salio la API, kiotomatiki.
- Ombi unaloghairi kabla halijaanza hurejeshewa fedha kikamilifu. Modeli inapoanza kuzalisha, kughairi ni ombi pekee: ikiwa modeli itamaliza, tokeo hutolewa na kutozwa.
- Ombi la `metered` linalofaulu hurejeshewa sehemu ya kiwango chake cha juu ambayo halikutumia.

Kipengee cha ombi huonyesha yote: `cost.credits`, `cost.charged` na `cost.refunded`.

## Hifadhi ya faili

Faili za matokeo huhifadhiwa kwenye hifadhi yetu. Unachagua, katika akaunti au kwa kila uendeshaji (`?storage=`):

| | Limehifadhiwa | Bei |
|---|---|---|
| Milele (`permanent`, chaguomsingi) | Hadi uzifute | 100 krediti za API ($ 0.10) kwa GB kwa mwezi |
| Siku 7 (`temporary`) | Siku 7 | Bila malipo |

Hifadhi ya kudumu hutozwa mara moja kwa siku kutoka kwenye salio la API: GB zilizohifadhiwa × bei ya kila mwezi ÷ siku za mwezi, kama
safu za leja za aina `storage`. Sehemu za krediti ya API hubebwa hadi siku inayofuata, kwa hiyo mwezi hujumlisha hasa
GB × 100 krediti za API (1 GB = 1024³ baiti; GB 10 zilizohifadhiwa kwa mwezi hugharimu
1,000 krediti za API). Salio haliwi chini ya sufuri: linaposhindwa kulipa, siku hiyo haitozwi,
unapokea barua pepe, na una siku 30 za kuongeza salio kabla faili zilizohifadhiwa kuwa za muda na
kufutwa siku 7 baadaye. Maelezo: [Faili](https://doitong.com/developers/docs/files#storage).

## Ongeza salio

Ongeza pesa kwenye salio la API katika [https://doitong.com/developers/dashboard#balance](https://doitong.com/developers/dashboard#balance). Salio linapokuwa dogo sana, uendeshaji hujibu
`402 insufficient_credits` pamoja na `top_up_url`. Kila ufunguo wa API pia unaweza kuwekewa bajeti yake ya juu kwa krediti za API
(tazama [Uthibitishaji](https://doitong.com/developers/docs/authentication#credit-budgets)).
