GigaChat 2 Max API — price in US dollars

What GigaChat 2 Max is

GigaChat 2 Max is the previous generation of Sber’s GigaChat family. It has a 131,072-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.

GigaChat is not on OpenRouter as of October 2026, and a direct contract for the GigaChat API needs a Russian company or sole proprietor. Here a company outside Russia gets GigaChat 2 Max with an English invoice in US dollars from Kosareva Cloud LLC (Armenia) and pays by bank transfer. Requests to GigaChat 2 Max are processed in Russia.

One key opens more than GigaChat 2 Max: the catalog has over a hundred models, including the other GigaChat and 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.

GigaChat 2 Max strengths and weaknesses

Who it suits. One use: keeping an existing integration running until it moves to the third generation.

What to compare it with. Against GigaChat 3.5 Ultra ($1.58 / $4.73) it loses on price, context and features at once. The absence of service overhead does not make up the difference: $9.32 against $1.58 per million — Ultra’s extra 55 or so tokens don’t weigh that much at any request size.

GigaChat 2 Max among the GigaChat models

GigaChat 2 Max is the oldest and most expensive model of the family. GigaChat 3.5 Ultra has twice the context at a sixth of the input price, GigaChat 3 Pro and GigaChat 3 Lightning are cheaper still. Moving usually means changing the model name and rerunning your tests.

GigaChat 2 Max price in US dollars

Approximate: the catalog price (797.07 ₽ per 1M tokens for both input and output) 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. The vendor’s service prompt, about 11 tokens per request, is billed as input. You pay only for actual usage.

What a typical task costs on GigaChat 2 Max

A price per million tokens says little on its own, so here are four common tasks at GigaChat 2 Max rates: $9.32 per million input tokens and $9.32 per million output tokens, plus the vendor’s service prompt of about 11 input tokens on every request.

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

At $9.32 per million input tokens and $9.32 per million output tokens; approximate, at 85.5 ₽ per $1. Each request also carries the vendor’s service prompt of about 11 input tokens — it is already in the numbers. Billed for actual usage.

How to connect GigaChat 2 Max

Use the standard OpenAI SDK with the kosareva.cloud base_url and the model gigachat-2-max. 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="gigachat-2-max",
    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": "gigachat-2-max",
        "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":"gigachat-2-max","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.

GigaChat 2 Max 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.

• Integrations whose prompts are tuned to GigaChat 2

What to keep in mind with GigaChat 2 Max

If you are on it, count the cost of moving: usually it is enough to change the model name and run your tests. With a sixfold difference on input, the move pays off in the first month.

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 GigaChat 2 Max”: 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.
