## 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 increases the model's confidence in its responses; a higher temperature increases creativity and diversity. 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 `0.2`.
  - `"frequency penalty"`: `float`  
    Similar to the presence penalty, this reduces the model’s tendency to repeat the same words frequently. Defaults to `0.7`.
  - `"max_token"`: `integer`  
    The maximum length of the model’s output, measured in the number of tokens (words or pieces of words). Defaults to `512`.  
- `"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 uses a hybrid of weighted keyword similarity and vector cosine similarity 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 `8`.
  - `"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.
  - `"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.

## Update chat assistant

**PUT** `/api/v1/chats/{chat_id}`

Updates configurations for a specified chat assistant.

### Request

- Method: PUT
- URL: `/api/v1/chats/{chat_id}`
- 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

```bash
curl --request PUT \
     --url http://{address}/api/v1/chats/{chat_id} \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <YOUR_API_KEY>' \
     --data '
     {
          "name":"Test"
     }'
```

#### Parameters

- `chat_id`: (*Path parameter*)  
  The ID of the chat assistant to update.
- `"name"`: (*Body parameter*), `string`, *Required*  
  The revised 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 dictionary with the following values will be generated as the default. An `llm` 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 increases the model's confidence in its responses; a higher temperature increases creativity and diversity. 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 `0.2`.
  - `"frequency penalty"`: `float`  
    Similar to the presence penalty, this reduces the model’s tendency to repeat the same words frequently. Defaults to `0.7`.
  - `"max_token"`: `integer`  
    The maximum length of the model’s output, measured in the number of tokens (words or pieces of words). Defaults to `512`.  
- `"prompt"`: (*Body parameter*), `object`  
  Instructions for the LLM to follow.  A `prompt` object contains the following attributes:  
  - `"similarity_threshold"`: `float` RAGFlow uses a hybrid of weighted keyword similarity and vector cosine similarity 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 `8`.
  - `"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.
  - `"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.

### Response

Success:

```json
{
    "code": 0
}
```

Failure:

```json
{
    "code": 102,
    "message": "Duplicated chat name in updating dataset."
