:::tip API GROUPING Chat Assistant Management :::

Create chat assistant

RAGFlow.create_chat(

    avatar: str = "", 
    knowledgebases: list[str] = [], 
    llm: Chat.LLM = None, 
    prompt: Chat.Prompt = None
) -> Chat

Creates a chat assistant.

Parameters

The following shows the attributes of a Chat object:

name: `str`, Required????????

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

avatar: `str`

Base64 encoding of the avatar. Defaults to "".

knowledgebases: `list[str]`

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

llm: `Chat.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.

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 returned.
temperature, float
Controls the randomness of the model's predictions. A lower temperature increases the model's conficence 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, 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: `Chat.Prompt`

Instructions for the LLM to follow. A Prompt object contains the following attributes:

"similarity_threshold": float A similarity score to evaluate distance between two lines of text. It's weighted keywords similarity and vector cosine similarity. If the similarity between query and chunk is less than this threshold, the chunk will be filtered out. Defaults to 0.2.
"keywords_similarity_weight": float It's weighted keywords similarity and vector cosine similarity or rerank score (0~1). Defaults to 0.7.
"top_n": int Not all the chunks whose similarity score is above the 'similarity threshold' will be feed to LLMs. LLM can only see these 'Top N' chunks. Defaults to 8.
"variables": list[dict[]] If you use dialog APIs, the variables might help you chat with your clients with different strategies. The variables are used to fill in the 'System' part in prompt in order to give LLM a hint. The 'knowledge' is a very special variable which will be filled-in with the retrieved chunks. All the variables in 'System' should be curly bracketed. Defaults to [{"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 "".
"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 retrieved, 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. Defaults to You are an intelligent assistant. Please summarize the content of the dataset 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..
