 - 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`  
-  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: `str`
-
-Instructions for the LLM to follow.
-
-- `"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 knowledge base 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`.
