Russian without an accent
Alice AI writes natural Russian, without the stiff phrasing of translated output: customer emails, marketing, editing.
Alice AI and YandexGPT through an OpenAI-compatible API, with the same key as the rest of our catalog. Requests are processed in Russia; companies abroad pay by USD invoice from $50.

In short: Yandex models are not on OpenRouter as of October 2026. Through kosareva.cloud you connect the Yandex language models — Alice AI, YandexGPT and embeddings — with one key: only base_url and the key change, your OpenAI SDK code stays the same. Requests are processed in Russia. A company outside Russia pays by USD invoice from Kosareva Cloud LLC (Armenia), minimum $50.

Not a replacement for Western flagships in code and complex reasoning, but a precise choice for Russian text and for tasks that require processing in Russia.
Alice AI writes natural Russian, without the stiff phrasing of translated output: customer emails, marketing, editing.
Requests to Yandex models are processed in Russia. A key marked “Russia-hosted models only” cannot reach a model hosted elsewhere, even by mistake.
YandexGPT 5.1 Pro costs $13.10 per million tokens for both input and output: a long answer costs no more than a long prompt.
A repeated prompt prefix on Flash is billed at $0.41 per million tokens instead of $1.64. The other Yandex models have no cache discount.
YandexGPT context is 32,768 tokens, Alice AI’s is 131,072. A whole long contract, code and agents are better served by other models in the catalog — with the same key.
The Yandex Embeddings pair costs $0.17 per million tokens, chunks up to 8,192 tokens: documents go to Doc, queries to Query.
Approximate prices in US dollars per 1M tokens: the catalog price in rubles divided by 85.5 ₽ per $1, ID Bank’s non-cash rate on 3 October 2026. Your balance is kept in rubles.
Yandex’s flagship: 131K context, natural Russian, processed in Russia.
The fast Alice AI: five times cheaper on input, with a cache discount and a 65,536-token context.
Current YandexGPT generation: one price for input and output, processed in Russia.
The smaller YandexGPT: four times cheaper than 5.1 Pro, with the same context.
Previous YandexGPT Pro generation, kept for integrations already tuned to it.
Turns documents into vectors for semantic search: knowledge base, RAG, deduplication.
OpenAI-compatible endpoint: only base_url and the model name change, the code stays the same.
Choose “Company or sole proprietor” → “In another country”: country, registration number, tax ID if you have one.
“Top up balance” → “Issue invoice (companies)”: an English invoice in US dollars, minimum $50, due in 10 days.
Create a key and set the model: alice-ai, alice-ai-flash, yandexgpt-5-1-pro or yandexgpt-5-lite. Usage shows up in the dashboard right away.

The key, the data and choosing a model.
At kosareva.cloud the key is issued in the dashboard right after registration and works with the Yandex models and the rest of the catalog. Yandex models are not on OpenRouter as of October 2026.
The API gives you Alice AI, the language model Alice answers with. There is no voice, skills or smart home in the API: text in, text out — for your own chats, bots and document processing.
Alice AI — for texts where natural Russian matters. Alice AI Flash — for a stream of short answers: five times cheaper on input, and the only Yandex model with a cache discount. YandexGPT 5.1 Pro — when answers are long: input and output cost the same, $13.10 per million. YandexGPT 5 Lite — for labelling and classification at volume.
Requests to Yandex models are processed in Russia, on Yandex infrastructure. To make sure a key can’t reach a model hosted elsewhere, mark it “Russia-hosted models only” when you create it. If GDPR applies to you, assess the transfer before sending personal data.

Not yet. If you need a EUR invoice, write to ceo@kosareva.cloud or Telegram @kosareva_cloud.
Create a key, send a dozen real requests to Alice AI and YandexGPT and compare the answers with the model you use now.
