### Create chat completion

**POST** `/api/v1/chats_openai/{chat_id}/chat/completions`

Creates a model response for a given chat conversation.

This API follows the same request and response format as OpenAI's API. It allows you to interact with the model in a manner similar to how you would with [OpenAI's API](https://platform.openai.com/docs/api-reference/chat/create).

#### Request

- Method: POST
- URL: `/api/v1/chats_openai/{chat_id}/chat/completions`
- Headers:
  - `'content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:
  - `"model"`: `string`
  - `"messages"`: `object list`
  - `"stream"`: `boolean`

##### Request example

```bash
curl --request POST \
     --url http://{address}/api/v1/chats_openai/{chat_id}/chat/completions \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data '{
        "model": "model",
        "messages": [{"role": "user", "content": "Say this is a test!"}],
        "stream": true
      }'
```

##### Request Parameters

- `model` (*Body parameter*) `string`, *Required*  
  The model used to generate the response. The server will parse this automatically, so you can set it to any value for now.

- `messages` (*Body parameter*) `list[object]`, *Required*  
  A list of historical chat messages used to generate the response. This must contain at least one message with the `user` role.

- `stream` (*Body parameter*) `boolean`  
  Whether to receive the response as a stream. Set this to `false` explicitly if you prefer to receive the entire response in one go instead of as a stream.

#### Response

## CHAT ASSISTANT MANAGEMENT

---

### Create chat assistant

**POST** `/api/v1/chats`

Creates a chat assistant.

#### Request

- Method: POST
- URL: `/api/v1/chats`
- Headers:
  - `'content-Type: application/json'`
  - `'Authorization: Bearer <YOUR_API_KEY>'`
- Body:
  - `"name"`: `string`
  - `"avatar"`: `string`
  - `"dataset_ids"`: `list[string]`
  - `"llm"`: `object`
  - `"prompt"`: `object`

##### Request example

```shell
curl --request POST \
     --url http://{address}/api/v1/chats \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data '{
    "dataset_ids": ["0b2cbc8c877f11ef89070242ac120005"],
    "name":"new_chat_1"
}'
```

##### Request parameters

- `"name"`: (*Body parameter*), `string`, *Required*  
  The name of the chat assistant.
- `"avatar"`: (*Body parameter*), `string`  
  Base64 encoding of the avatar.
- `"dataset_ids"`: (*Body parameter*), `list[string]`  
  The IDs of the associated datasets.
- `"llm"`: (*Body parameter*), `object`  
  The LLM settings for the chat assistant to create. If it is not explicitly set, a JSON object with the following values will be generated as the default. An `llm` JSON object contains the following attributes:  
  - `"model_name"`, `string`  
    The chat model name. If not set, the user's default chat model will be used.  
  - `"temperature"`: `float`  
    Controls the randomness of the model's predictions. A lower temperature results in more conservative responses, while a higher temperature yields more creative and diverse responses. Defaults to `0.1`.  
  - `"top_p"`: `float`  
    Also known as “nucleus sampling”, this parameter sets a threshold to select a smaller set of words to sample from. It focuses on the most likely words, cutting off the less probable ones. Defaults to `0.3`  
  - `"presence_penalty"`: `float`  
    This discourages the model from repeating the same information by penalizing words that have already appeared in the conversation. Defaults to `0.4`.
  - `"frequency penalty"`: `float`  
    Similar to the presence penalty, this reduces the model’s tendency to repeat the same words frequently. Defaults to `0.7`.
- `"prompt"`: (*Body parameter*), `object`  
  Instructions for the LLM to follow. If it is not explicitly set, a JSON object with the following values will be generated as the default. A `prompt` JSON object contains the following attributes:  
  - `"similarity_threshold"`: `float` RAGFlow employs either a combination of weighted keyword similarity and weighted vector cosine similarity, or a combination of weighted keyword similarity and weighted reranking score during retrieval. This argument sets the threshold for similarities between the user query and chunks. If a similarity score falls below this threshold, the corresponding chunk will be excluded from the results. The default value is `0.2`.
  - `"keywords_similarity_weight"`: `float` This argument sets the weight of keyword similarity in the hybrid similarity score with vector cosine similarity or reranking model similarity. By adjusting this weight, you can control the influence of keyword similarity in relation to other similarity measures. The default value is `0.7`.
  - `"top_n"`: `int` This argument specifies the number of top chunks with similarity scores above the `similarity_threshold` that are fed to the LLM. The LLM will *only* access these 'top N' chunks.  The default value is `6`.
  - `"variables"`: `object[]` This argument lists the variables to use in the 'System' field of **Chat Configurations**. Note that:  
    - `"knowledge"` is a reserved variable, which represents the retrieved chunks.
    - All the variables in 'System' should be curly bracketed.
    - The default value is `[{"key": "knowledge", "optional": true}]`.
  - `"rerank_model"`: `string` If it is not specified, vector cosine similarity will be used; otherwise, reranking score will be used.
  - `top_k`: `int` Refers to the process of reordering or selecting the top-k items from a list or set based on a specific ranking criterion. Default to 1024.
  - `"empty_response"`: `string` If nothing is retrieved in the dataset for the user's question, this will be used as the response. To allow the LLM to improvise when nothing is found, leave this blank.
  - `"opener"`: `string` The opening greeting for the user. Defaults to `"Hi! I am your assistant, can I help you?"`.
  - `"show_quote`: `boolean` Indicates whether the source of text should be displayed. Defaults to `true`.
  - `"prompt"`: `string` The prompt content.
