Alice AI API — price in US dollars

What Alice AI is

Alice AI is the flagship Yandex language model, the one Alice answers with. It has a 131K-token context window, takes text in and gives text out, and belongs to the chat and text generation category. Through kosareva.cloud it is available via one OpenAI-compatible API: the same code as for OpenAI — just change base_url and the key.

Alice AI is not available on OpenRouter as of October 2026. Here a company outside Russia gets it with an English invoice in US dollars from Kosareva Cloud LLC (Armenia) and pays by bank transfer. Requests to Alice AI are processed in Russia, on Yandex infrastructure.

One key opens more than Alice AI: the catalog has over a hundred models, including the other Yandex models. That matters more than it seems: models age within months, and moving to the next version is one line of code, not a new contract and a new integration.

Alice AI strengths and weaknesses

Who it suits. Russian texts where natural language matters: marketing, customer emails, editing. And tasks that require processing in Russia.

What to compare it with. Against Alice AI Flash ($1.64 / $3.27): five times more expensive on input and noticeably smarter. Against YandexGPT 5.1 Pro ($13.10 for both input and output): cheaper on input, more expensive on output, with four times the context.

Alice AI among the Yandex models

Of the Yandex models in our catalog, Alice AI has the largest context: 131K tokens, against 65K for Alice AI Flash and 32K for YandexGPT 5.1 Pro, 5 Pro and 5 Lite. It is the one to pick when the request carries a long document; for a stream of short answers, Flash costs a fifth of the price on input.

Alice AI price in US dollars

Approximate: the catalog price (700 ₽ and 1,680 ₽ per 1M tokens) divided by 85.5 ₽ per $1, ID Bank’s non-cash rate on 3 October 2026. Your balance is kept in rubles; a USD invoice is converted at ID Bank’s non-cash rate on the invoice date. You pay only for actual usage.

What a typical task costs on Alice AI

A price per million tokens says little on its own, so here are four common tasks at Alice AI rates: $8.19 per million input tokens and $19.65 per million output tokens.

Calculated from the current kosareva.cloud price list, in US dollars at 85.5 ₽ per $1.

How to connect Alice AI

Use the standard OpenAI SDK with the kosareva.cloud base_url and the model alice-ai. In existing code you change exactly two lines: the address and the key.

Python, OpenAI SDK

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_KOSAREVA_KEY",
    base_url="https://api.kosareva.cloud/v1",
)

response = client.chat.completions.create(
    model="alice-ai",
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)

Python without the SDK: requests

import requests

response = requests.post(
    "https://api.kosareva.cloud/v1/chat/completions",
    headers={"Authorization": "Bearer YOUR_KOSAREVA_KEY"},
    json={
        "model": "alice-ai",
        "messages": [{"role": "user", "content": "Hello!"}],
    },
    timeout=600,
)
print(response.json()["choices"][0]["message"]["content"])

cURL

curl https://api.kosareva.cloud/v1/chat/completions \
  -H "Authorization: Bearer YOUR_KOSAREVA_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"alice-ai","messages":[{"role":"user","content":"Hello!"}]}'

The same key works with any client that supports an OpenAI-compatible endpoint: LangChain, LlamaIndex, Cursor, Continue, n8n. You don’t need a separate key per model — one key opens the whole catalog.

Alice AI endpoints and parameters

The gateway follows the OpenAI schema, so parameter names and the response format are the ones you know. One base address for every model in the catalog.

Request long answers with stream: true: with a large max_tokens, a regular request stays silent until generation ends and can hit your HTTP client’s timeout. In streaming mode the first tokens arrive within seconds, and the timeout problem goes away.

What to keep in mind with Alice AI

Don’t build a dialogue that keeps growing its history on this model: with no cache discount, every new turn pays again for the whole previous context. Send one compact request with the fragments you need instead of a long conversation — with no cache discount, this is where most of the savings are.

First, context runs out faster than it seems. In a dialogue the whole conversation goes into the input, not just the last message, so a long chat gets more expensive with every turn. If the history isn’t needed for the answer, trim it: savings on input tokens usually matter more than picking a cheaper model.

Second, the 131K-token window is shared between the request and the answer: the more you send, the less room the model has to generate. Set max_tokens on purpose, not “with a margin”.

Third, the balance is shared by all models in the catalog. You don’t have to decide in advance how much money to “put on Alice AI”: the same funds go to any other model if you switch tomorrow. Usage per model is shown in the dashboard on a separate line, with the number of requests and tokens.
