knowledgebases: list[DataSet]

Select knowledgebases associated. Defaults to ["kb1"].

id: str

The id of the created chat. Defaults to "".

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
  Large language chat model. If it is None, it will return the user's default model.
• 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 you need LLM to follow when LLM answers questions, like character design, answer length and answer language etc.

Defaults:

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.
