## Create chat

Creates a chat assistant.

```python
RAGFlow.create_chat(
    name: str = "assistant", 
    avatar: str = "path", 
    knowledgebases: List[DataSet] = ["kb1"], 
    llm: Chat.LLM = None, 
    prompt: Chat.Prompt = None
) -> Chat
```

### Returns

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

#### name: `str`

The name of the chat assistant. Defaults to `"assistant"`.

#### avatar: `str`

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

#### knowledgebases: `list[str]`

The associated knowledge bases. Defaults to `["kb1"]`.

#### llm: `LLM`

The llm of the created chat. Defaults to `None`. When the value is `None`, a dictionary with the following values will be generated as the default.

- **model_name**, `str`  
  The chat model name. If it is `None`, the user's default chat model will be returned.  
- **temperature**, `float`  
  This parameter controls the randomness of predictions by the model. A lower temperature makes the model more confident in its responses, while a higher temperature makes it more creative and diverse. 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**, `int`  
  This sets the maximum length of the model’s output, measured in the number of tokens (words or pieces of words). Defaults to `512`.

#### Prompt: `str`

Instructions for LLM's responses, including character design, answer length, and language. Defaults to:

```
You are an intelligent assistant. Please summarize the content of the knowledge base to answer the question. Please list the data in the knowledge base and answer in detail. When all knowledge base content is irrelevant to the question, your answer must include the sentence "The answer you are looking for is not found in the knowledge base!" Answers need to consider chat history.
      Here is the knowledge base:
      {knowledge}
      The above is the knowledge base.
```

### Examples

```python
from ragflow import RAGFlow

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

  - `"frequency penalty"`, `float` Similar to the presence penalty, this reduces the model’s tendency to repeat the same words frequently.
  - `"max_token"`, `int` This sets the maximum length of the model’s output, measured in the number of tokens (words or pieces of words).
