What is InstructGPT?

InstructGPT is an AI language model created by OpenAI. It is a variant of the GPT framework specifically designed to generate text based on directions or prompts. Unlike regular GPT models that produce coherent and relevant compositions based on input, InstructGPT is fine-tuned to follow the directions in a prompt and give specific responses. It is a finetuned GPT-3 model.

The motivation behind InstructGPT is to make AI more practical in real-world scenarios where users may require specific instructions or how-to guidance. Training InstructGPT using a mix of supervised fine-tuning and reinforcement learning from human feedback can create more focused and instructional answers.

To effectively use InstructGPT, users provide clear and detailed directions in the prompt, specifying the preferred format or structure and, if needed, asking the model to think step-by-step or provide reasoning. It is important to review and edit the generated text to ensure it meets the requirements, as InstructGPT produces text based on patterns in its training data and does not truly understand the world.

InstructGPT can be applied to various tasks, like generating code or programming instructions, offering answers to specific questions or facts, creating multi-step directions or tutorials, and even drafting emails or other professional communications. However, it is advisable to consult human experts for safety-critical jobs or those requiring expert judgment.

What is an AI Language Model?

An AI language model is a type of machine learning algorithm that is trained on large amounts of text data to be able to generate or process human language. Some key things to know about AI language models:

• They are based on deep learning techniques, most commonly using neural network architectures like LSTM or Transformer networks.
• Major language models are trained on huge text corpora (billions or trillions of words) before being specialized for tasks through fine-tuning. This trained approach helps them learn rich linguistic patterns and semantics.
• Popular models include GPT, BERT, and T5 which can be fine-tuned for generative tasks like text summarization or question answering, as well as discriminative tasks like sentiment analysis or text classification.
• State-of-the-art models exhibit broad, context-dependent language understanding but don’t comprehend language in the way humans do. They don’t have subjective experiences.
• Applications include chatbots, virtual assistants, automation tools, content generation aids, and more. Larger models continue to push the boundaries of what’s possible with AI-generated text.
• Issues around bias, factuality, and appropriateness of generated text are actively studied to ensure the safe, truthful, and fair application of these powerful language models.

Instruct GPT vs Chat GPT:

ChatGPT is OpenAI’s free-to-use AI chatbot that uses the gpt-3.5-turbo AI model. This model is meant to be a conversational AI model that will give responses in natural language, just like a human would. GPT-3.5 Turbo is a more flexible large language model aimed at generating descriptive responses and understanding tasks. In contrast, the InstructGPT model is briefer and to the point. It follows instructions more carefully and produces results that are more aligned with the users’ query. Here are some points to help understand the differences more easily:

• GPT-3 based AIs (like ChatGPT) have been known to produce false information to try and fulfill a request. InstructGPT models are better at following instructions.
• The InstructGPT models are trained with humans using a technique called Reinforcement Learning from Human Feedback (RLFH). Humans train the model by ranking several outputs to finetune its responses.
• Because the GPT-3 models are trained on a large dataset of internet text, it can sometimes generate toxic or harmful statements.
• The GPT-3 models are meant to be conversational and are often not aligned with a user’s request.
• InstructGPT is trained through human feedback which makes its

How to use InstructGPT?

Right now, ChatGPT still uses the gpt-3.5-turbo model. If you want to try InstructGPT, you will have to get an OpenAI API key and then use the “text-xxxxx-001” engine when using the API call (E.g. text-davinci-001). Currently, there is no InstructGPT online playground for you to use since it is still in beta.

1. Goto OpenAI and create an account
2. Navigate to the API section
3. Create a new API key – remember to copy the key and save it because it won’t be shown again
4. In your application, use the following model: model=”text-davinci-001″

Afterword:

OpenAI’s InstructGPT represents an innovative step forward in the capability of AI systems to understand and respond to specific informational needs. As with other language models developed by OpenAI, it shows the immense potential of large neural networks pre-trained on vast text corpora to acquire broad linguistic knowledge. InstructGPT then leverages fine-tuning techniques to specialize this knowledge for the targeted use of generating step-by-step instructions. As AI and machine learning continue to progress, we can expect interactive instructional assistants to become even more helpful. New techniques in natural language processing, computer vision, speech recognition and other areas will allow systems to incorporate multi-modal information beyond text.
