• SHOW_USAGE: Whether to show OpenAI token usage information after each response
• MAX_TOKENS: Upper bound on how many tokens the ChatGPT API will return
• MAX_HISTORY_SIZE: Max number of messages to keep in memory, after which the conversation will be summarised to avoid excessive token usage (#34)
• MAX_CONVERSATION_AGE_MINUTES: Maximum number of minutes a conversation should live, after which the conversation will be reset to avoid excessive token usage

    'model': 'gpt-3.5-turbo',

    # Number between -2.0 and 2.0. Positive values penalize new tokens based on whether
    # they appear in the text so far, increasing the model's likelihood to talk about new topics. Defaults to 0
    'presence_penalty': 0,
    
    # Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing
