CHAT ASSISTANT MANAGEMENT

Create chat assistant

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.
max_token: int
The maximum length of the model’s output, measured in the number of tokens (words or pieces of words). Defaults to 512. If disabled, you lift the maximum token limit, allowing the model to determine the number of tokens in its responses.

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 "".
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

"prompt" : Instructions for the LLM to follow.
- "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 rerank 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 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 "".
- "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.

Returns

Success: No value is returned.
Failure: Exception
