Yenisei Free: a new model in every Yenisei product

The Yenisei lineup now includes Yenisei Free, a model at a nominal price: 0.01 ₽ per million input tokens and the same for output. It is available on every plan and in all of our products: in Chat, in Agent, in CLI and via the API.

What it can do

• holds a conversation in Russian and answers without lengthy deliberation;
• accepts text and images as input: screenshots, photos, diagrams;
• calls tools, so it works for agents too;
• handles about 98 thousand tokens in a single request.

For everyday questions, short texts and first experiments, it is enough. When the task gets harder, switch to Yenisei 100 or Yenisei Max: all it takes is changing the model name.

How to call it via the API

curl https://api.yenisei.ru/v1/chat/completions \
  -H "Authorization: Bearer $YENISEI_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "yenisei-free",
    "messages": [
      {"role": "user", "content": "Put together a plan for a weekend trip to Krasnoyarsk."}
    ]
  }'
