Alice AI Flash API — price in US dollars

What Alice AI Flash is

Alice AI Flash is the fast version of Alice, the Yandex language model. It has a 65,536-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.

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

One key opens more than Alice AI Flash: 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 Flash strengths and weaknesses

Who it suits. High-volume tasks in Russian: chat answers, short texts, request classification, email drafts. Anything where speed and volume matter more than depth.

What to compare it with. Against Alice AI ($8.19 / $19.65): five times cheaper on input and simpler; for a high-volume stream the difference in quality is rarely worth paying five times more. Against YandexGPT 5 Lite ($3.27 for both input and output): half the input price, the same output price, twice the context and a cache discount.

Alice AI Flash among the Yandex models

Alice AI Flash has the lowest input price of the Yandex chat models in our catalog, $1.64 per million tokens, and shares the lowest output price, $3.27, with YandexGPT 5 Lite. Its 65K context is half of Alice AI’s 131K and twice the 32K of YandexGPT 5.1 Pro, 5 Pro and 5 Lite. It is also the only Yandex model with a cache discount.

Alice AI Flash price in US dollars

Approximate: the catalog price (140 ₽, 280 ₽ and 35 ₽ 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 Flash

A price per million tokens says little on its own, so here are four common tasks at Alice AI Flash rates: $1.64 per million input tokens and $3.27 per million output tokens.

Calculated from the current kosareva.cloud price list, in US dollars at 85.5 ₽ per $1, without the cache discount: when the start of the prompt repeats, cached input lowers these sums further.

How to connect Alice AI Flash

Use the standard OpenAI SDK with the kosareva.cloud base_url and the model alice-ai-flash. 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-flash",
    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-flash",
        "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-flash","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 Flash 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 Flash

Here the cache works, and that is its main advantage over Alice AI: keep the system prompt and the fixed part of the context unchanged at the start of the request, and repeated input is billed at $0.41 per million instead of $1.64 — a quarter of the price. On a stream of similar requests this makes a visible difference to the bill.

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 65K-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 Flash”: 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.
