# Kimi Model

Call Kimi K3 through the shared Chat Completions endpoint.

POST https://api.apihop.ai/v1/chat-completions

Kimi K3 is available through the Common Chat Completions endpoint, with both non-streaming and SSE streaming text responses.

```text
POST https://api.apihop.ai/v1/chat-completions
```

## Available Model

| `model` value | Type | Non-streaming | SSE streaming |
| --- | --- | --- | --- |
| `kimi-k3` | Text chat | Yes | Yes |

## Authentication

```http
Authorization: Bearer YOUR_API_KEY
Content-Type: application/json
```

## Non-streaming Request

```json
{
  "model": "kimi-k3",
  "messages": [
    {
      "role": "system",
      "content": "You are a product analysis assistant."
    },
    {
      "role": "user",
      "content": "Break this requirement into goals, constraints, and acceptance criteria."
    }
  ],
  "stream": false
}
```

## Streaming Request

```json
{
  "model": "kimi-k3",
  "messages": [
    {
      "role": "user",
      "content": "Create a pre-release checklist."
    }
  ],
  "stream": true
}
```

This endpoint returns one complete JSON response by default. Set `stream: true` explicitly when you need SSE streaming.

## Request Fields

### `model` (string, required)

Use `kimi-k3`.

### `messages` (object[], required)

OpenAI Chat Completions style messages. Each message contains `role` and `content`.

### `stream` (boolean, Default: false)

`true` returns SSE; `false` returns one complete JSON response.

### `max_tokens` (integer)

Optional output token allowance. Omit it to use the upstream default. Reasoning and the final answer share this allowance: a small value may end with `finish_reason: "length"` before any answer text is produced. A larger allowance may increase output usage and cost.

### `max_completion_tokens` (integer)

Compatibility alternative to `max_tokens`. The selected model determines support.

### `n` (integer, Default: 1)

Only `n=1` is supported. Each request returns one response choice.

See [Common Chat Completions](https://apihop.ai/en/docs/api-reference/common-chat-completions) for shared fields such as `temperature`, `top_p`, `frequency_penalty`, `presence_penalty`, and `stop`. `kimi-k3` accepts these standard fields, but not every parameter necessarily produces a measurable semantic change.

## Success Response

```json
{
  "id": "chatcmpl_...",
  "object": "chat.completion",
  "created": 1787200000,
  "model": "kimi-k3",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "Goal: define the problem and expected outcome..."
      },
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 24,
    "completion_tokens": 86,
    "total_tokens": 110
  }
}
```

## Usage Notes

- The request body's `model` must be the public model ID listed in the Available Model table.
- Product names, display names, and other aliases are not accepted in place of the public model ID.
- This page applies only to Chat Completions requests sent to

`POST https://api.apihop.ai/v1/chat-completions`, not OpenAI Responses or Claude Messages.

- Use `GET https://api.apihop.ai/v1/models` for the models visible to the current API Key, and use the console for current pricing.

      "content": "You are a product analysis assistant."
    },

Solicitud con streaming

  "messages": [
    {
      "role": "user",
      "content": "Create a pre-release checklist."
    }
  ],
  "stream": true
}

Este endpoint devuelve una respuesta JSON completa de forma predeterminada. Establece stream: true explícitamente cuando necesites streaming SSE.

Campos de solicitud

modelstringobligatorio

Usa kimi-k3.

messagesobject[]obligatorio

Mensajes al estilo OpenAI Chat Completions. Cada mensaje contiene role y content.

streambooleanPredeterminado: false

true devuelve SSE; false devuelve una respuesta JSON completa.

max_tokensinteger

Límite opcional de tokens de salida. Omítelo para usar el valor predeterminado del proveedor. El razonamiento y la respuesta final comparten este límite: un valor pequeño puede terminar con finish_reason: "length" antes de producir texto de respuesta. Un límite mayor puede incrementar el uso de salida y el coste.

max_completion_tokensinteger

Alternativa de compatibilidad a max_tokens. El modelo elegido determina la compatibilidad.

nintegerPredeterminado: 1

Solo se admite n=1. Cada solicitud devuelve una opción de respuesta.

Consulta Chat Completions común para campos compartidos como temperature, top_p, frequency_penalty, presence_penalty y stop. kimi-k3 acepta estos campos estándar, pero no todos los parámetros producen necesariamente un cambio semántico medible.

El campo model del cuerpo debe ser el ID público indicado en la tabla de modelos disponibles.
Los nombres de producto, nombres visibles y otros alias no se aceptan en lugar del ID público del modelo.
Esta página se aplica solo a solicitudes de Chat Completions enviadas a POST https://api.apihop.ai/v1/chat-completions, no a OpenAI Responses ni Claude Messages.
