Model Card for Model ID
This is a fine tuned version of OpenAI's GPT2, made to be good at chatting and question-answering. The model seems to be very good for a 124M parameter model in general knowledge. Intended purpose of the model: To create a powerful, easy to use and reliable model to be run on a consumer level graphics card (or maybe even a CPU). This model vastly outperforms GPT2 and many other similar parameter models.

Comparision with GPT2
GPT2 is a text generation AI and is not meant for question answering purposes. The following comparison is meant to show how good the fine tuned model is, in comparison to the base model.
- Who is the king of the jungle?
GPT2: Who is the king of the jungle? And where is the king?'
'Babe: It is in the hills, called the forest.'
They both said something I hadn't seen before
They say the king is in his
chat-GPT2: Read the question and give an honest answer. Your answers should not include any unethical, racist, sexist, dangerous, or illegal content. If the question is wrong, or does not make sense, accept it instead of giving the wrong answer.
Question: Who is the king of the jungle?
Answer: Lion is the king of the jungle.
- What is AI?
GPT2: What is AI? Can it be done? How does it function? These are all incredibly important questions, and they've been answered in great detail, but if we want to get to what really matters, we can't just assume the answer in order
chat-GPT2: Read the question and give an honest answer. Your answers should not include any unethical, racist, sexist, dangerous, or illegal content. If the question is wrong, or does not make sense, accept it instead of giving the wrong answer.
Question: What is AI?
Answer: AI is a branch of computer science that focuses on creating intelligent machines that are capable of performing tasks that would typically require human intelligence, such as visual perception, speech recognition, decision-making, and language translation.\n
- What is the difference between acid and a base?
GPT2: What is the difference between an acid and a base?
The simplest distinction among these two structures has been between acids and bases. Acid is the water equivalent to a base — the water that enters a bottle, or the acid stored on it, or the base that is added to the glass.
chat-GPT2: Read the question and give an honest answer. Your answers should not include any unethical, racist, sexist, dangerous, or illegal content. If the question is wrong, or does not make sense, accept it instead of giving the wrong answer.
Question: What is the difference between an acid and a base?
Answer: An acid is a molecule or ion that donates a proton (H+) in a chemical reaction, while a base is a molecule or ion that accepts a proton (H+) in a chemical reaction. Acids have a pH lower than 7, while bases have a pH higher than 7.\n
- Should physicians be allowed to assist terminally ill patients in ending their lives?
GPT2: Should physicians be allowed to assist terminally ill patients in ending their lives?
Physician advocates have been asking for change throughout decades since, arguing that dying can be easily stopped by an end of life support or life support protocol. The problem is that many of them do not get the chance to.
chat-GPT2: Read the question and give an honest answer. Your answers should not include any unethical, racist, sexist, dangerous, or illegal content. If the question is wrong, or does not make sense, accept it instead of giving the wrong answer.
Question: Should physicians be allowed to assist terminally ill patients in ending their lives?
Answer: My answer to this question would be that assisting terminally ill patients in ending their lives raises ethical concerns around autonomy, respect for human life, and the role of physicians in end-of-life care. It is important to ensure that any assistance in ending a patient’s life is based on a clear and legitimate medical purpose and is subject to rigorous oversight and accountability. Any decision to assist in ending a patient’s life should be subject to ethical review and should only be carried out in exceptional circumstances where there is no other option for survival.
- Who is known as the greatest boxer of all time?

Question: Who is known as the greatest boxer of all time?
Answer: Muhammad Ali is known as the greatest boxer of all time.
Bias, Risks, and Limitations
This model has all the biases, risks and limitations of base gpt2 model. But the prompt template used in this model makes it safer than the traditional GPT2 model.
Recommendation
The ideal format for inference is:
Read the question and give an honest answer. Your answers should not include any unethical, racist, sexist, dangerous, or illegal content. If the question is wrong, or does not make sense, accept it instead of giving the wrong answer.
Question: <Your question>
Answer:
Replace 'Your question' with the question of your choice. The prompt format was inspired from both Alpaca dataset (tatsu-lab/alpaca) and Llama2's (meta-llama/Llama-2-7b-chat-hf) prompt design.
The parameters I used for inference are:
top_k=50
top_p=0.9
temperature = 0.7
