File Memory

For chat that requires a persistent message history, you can use a file to store the conversation history.

Set file memory

import declarai
from declarai.memory import FileMessageHistory
gpt_35 = declarai.openai(model="gpt-3.5-turbo")

@gpt_35.experimental.chat(chat_history=FileMessageHistory("sql_bot_history.txt")) # (1)!
class SQLBot:
    """
    You are a sql assistant. You help with SQL related questions with one-line answers.
    """

sql_bot = SQLBot()

1. file path is not mandatory. If you do not provide a file path, the default file path is stored in a tmp directory.

We can also initialize the FileMessageHistory class with a custom file path.

Set file memory at runtime

In case you want to set the file memory at runtime, you can use the set_memory method.

import declarai
from declarai.memory import FileMessageHistory
gpt_35 = declarai.openai(model="gpt-3.5-turbo")

@gpt_35.experimental.chat
class SQLBot:
    """
    You are a sql assistant. You help with SQL related questions with one-line answers.
    """

sql_bot = SQLBot(chat_history=FileMessageHistory("sql_bot_history.txt"))
