Models

Put a model id in the model field of a request. GET /v1/models gives the same list and needs no key. We make this table from our model catalogue each time that you open the page.

The table shows the frontier models first. The open models (Kimi, GLM, Qwen and MiniMax) come after them. Each open model has its own multiple, and it is smaller than the frontier multiple.

To check an official price, open the price page of the maker: Anthropic, OpenAI, Google, Moonshot AI, Z.ai, Qwen and MiniMax.

What GET /v1/models returns

The response has the OpenAI list format and the Anthropic list format. This is one entry:

{
  "id": "claude-haiku-4-5-20251001",
  "object": "model",
  "type": "model",
  "display_name": "claude-haiku-4-5-20251001",
  "owned_by": "kontinent",
  "maker": "anthropic",
  "formats": ["anthropic", "openai"],
  "endpoints": ["/v1/messages", "/v1/chat/completions"],
  "input_modalities": ["text", "image"],
  "context_window": 200000,
  "reasoning": false,
  "starter": true,
  "supported_parameters": ["tools", "vision"],
  "performance": null,
  "pricing": {
    "unit": "token",
    "usd_per_million_input": 0.2,
    "usd_per_million_output": 1,
    "usd_per_million_cached_input": 0.02,
    "usd_per_million_cache_write": 0.25,
    "multiple_of_list": 0.2,
    "list": {
      "usd_per_million_input": 1,
      "usd_per_million_output": 5,
      "usd_per_million_cached_input": 0.1,
      "usd_per_million_cache_write": 1.25
    }
  }
}

The JSON above is a copy. The live endpoint is always correct.

Capabilities

supported_parameters controls /v1/chat/completions. If you send tools, response_format or an image to a model that does not show that capability, you get a 400 error that names the parameter. We do not charge for that request.

On /v1/messages and /v1/responses, we send your body to the model as you wrote it. The model makes the decision about each field.

Models that think first

Some models think before they answer. We charge for that output as output tokens, but the response does not show it. In GET /v1/models, these models have "reasoning": true.

• On a short answer, the thought tokens can be most of the cost.
• A small max_tokens value can stop the model before it writes the answer. Then you get an empty answer and a charge for the thought tokens.

On /v1/chat/completions, you can send reasoning_effort to a GPT or Gemini model. We send it to the model without a change:

client.chat.completions.create(
    model="gemini-3.5-flash",
    messages=[{"role": "user", "content": "What is 2+2?"}],
    reasoning_effort="low",
)

Claude models think only when the request asks. On /v1/messages, send the thinking field of the Anthropic format.

Get one model

curl https://api.kontinentai.com/v1/models/claude-haiku-4-5-20251001

client.models.retrieve("claude-haiku-4-5-20251001")

An unknown id gets a 404 error. We never send your request to a different model.
