### Create chat completion

Creates a model response for the given historical chat conversation via OpenAI's API.

#### Parameters

##### model: `str`, *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: `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: `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.

#### Returns

- Success: Response [message](https://platform.openai.com/docs/api-reference/chat/create) like OpenAI
- Failure: `Exception`

#### Examples

```python
from openai import OpenAI

model = "model"
client = OpenAI(api_key="ragflow-api-key", base_url=f"http://ragflow_address/api/v1/chats_openai/<chat_id>")

stream = True
reference = True

completion = client.chat.completions.create(
    model=model,
    messages=[
        {"role": "system", "content": "You are a helpful assistant."},
        {"role": "user", "content": "Who are you?"},
        {"role": "assistant", "content": "I am an AI assistant named..."},
        {"role": "user", "content": "Can you tell me how to install neovim"},
    ],
    stream=stream,
    extra_body={"reference": reference}
)

if stream:
    for chunk in completion:
        print(chunk)
        if reference and chunk.choices[0].finish_reason == "stop":
            print(f"Reference:\n{chunk.choices[0].delta.reference}")
            print(f"Final content:\n{chunk.choices[0].delta.final_content}")

### Parse documents (with document status)

```python
DataSet.parse_documents(document_ids: list[str]) -> list[tuple[str, str, int, int]]
```

*Asynchronously* parses documents in the current dataset.

This method encapsulates `async_parse_documents()`. It awaits the completion of all parsing tasks before returning detailed results, including the parsing status and statistics for each document. If a keyboard interruption occurs (e.g., `Ctrl+C`), all pending parsing tasks will be cancelled gracefully.

#### Parameters

##### document_ids: `list[str]`, *Required*

The IDs of the documents to parse.

#### Returns

A list of tuples with detailed parsing results:

```python
[
  (document_id: str, status: str, chunk_count: int, token_count: int),
  ...
]
```
- `status`: The final parsing state (e.g., `success`, `failed`, `cancelled`).  
- `chunk_count`: The number of content chunks created from the document.  
- `token_count`: The total number of tokens processed.  

---

#### Example

```python
rag_object = RAGFlow(api_key="<YOUR_API_KEY>", base_url="http://<YOUR_BASE_URL>:9380")
dataset = rag_object.create_dataset(name="dataset_name")
documents = dataset.list_documents(keywords="test")
ids = [doc.id for doc in documents]

try:
    finished = dataset.parse_documents(ids)
    for doc_id, status, chunk_count, token_count in finished:
        print(f"Document {doc_id} parsing finished with status: {status}, chunks: {chunk_count}, tokens: {token_count}")
except KeyboardInterrupt:
    print("\nParsing interrupted by user. All pending tasks have been cancelled.")
except Exception as e:
    print(f"Parsing failed: {e}")
```

---

### Stop parsing documents

```python
DataSet.async_cancel_parse_documents(document_ids:list[str])-> None
```

Stops parsing specified documents.

#### Parameters

The IDs of the documents for which parsing should be stopped.

#### Returns

- Success: No value is returned.

## CHAT ASSISTANT MANAGEMENT

---

### Create chat assistant

```python
RAGFlow.create_chat(
    name: str, 
    avatar: str = "", 
    dataset_ids: list[str] = [], 
    llm: Chat.LLM = None, 
    prompt: Chat.Prompt = None
) -> Chat
```

Creates a chat assistant.

#### Parameters

##### name: `str`, *Required*

The name of the chat assistant.

##### avatar: `str`

Base64 encoding of the avatar. Defaults to `""`.

##### dataset_ids: `list[str]`

The IDs of the associated datasets. Defaults to `[""]`.

##### llm: `Chat.LLM`

The LLM settings for the chat assistant to create. Defaults to `None`. When the value is `None`, a dictionary with the following values will be generated as the default. An `LLM` object contains the following attributes:

- `model_name`: `str`  
  The chat model name. If it is `None`, 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 `0.2`.
- `frequency penalty`: `float`  
  Similar to the presence penalty, this reduces the model’s tendency to repeat the same words frequently. Defaults to `0.7`.

##### prompt: `Chat.Prompt`

Instructions for the LLM to follow.  A `Prompt` 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. 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`: `list[dict[]]` 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`: `str` If it is not specified, vector cosine similarity will be used; otherwise, reranking score will be used. Defaults to `""`.
- `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`: `str` 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. Defaults to `None`.
- `opener`: `str` The opening greeting for the user. Defaults to `"Hi! I am your assistant, can I help you?"`.
- `show_quote`: `bool` Indicates whether the source of text should be displayed. Defaults to `True`.
- `prompt`: `str` The prompt content.

#### Returns

- Success: A `Chat` object representing the chat assistant.
- Failure: `Exception`

#### Examples

```python
from ragflow_sdk import RAGFlow

rag_object = RAGFlow(api_key="<YOUR_API_KEY>", base_url="http://<YOUR_BASE_URL>:9380")
datasets = rag_object.list_datasets(name="kb_1")
