Open AI finally introduced GPT -4 on 14th March 2023, the advanced version of GPT-3.5. Before moving towards discussing GPT -4. Let me first explain in a few words for those who need to learn about the chat GPT.
What Is Chat GPT?
Chatbot GPT is an advanced AI language model developed by OpenAI. It leverages the power of the GPT-4 architecture to understand and generate human-like text. ChatGPT excels in diverse applications such as answering questions, composing text, offering suggestions, and engaging in conversation, making it a versatile tool for numerous industries and applications.
About GPT 4:
GPT 4 is more capable than its previous version and feels more like a human. The Open AI team tested it in more complex situations where they had to give a bar exam to solve & it performed well & scored top 10% of test takers. The team has fixed some bugs & improved theoretical foundations. Let’s discuss the essential additions in GPT 4 in more detail –
1- Visual Inputs
GPT 4 can understand your query through photographs, diagrams, or screenshots and answer in text outputs.
Example: You can upload an image & ask GPT 4 to write a few words about that image or just ask, “what is strange in this image.”
This feature is going to be very helpful in a variety of applications. However, you must wait for this feature, which currently needs to be available in GPT 4 access through GPT plus plan.
GPT-4 demonstrates improved steerability compared to its predecessors GPT-3.5, allowing users to guide the AI’s responses more effectively. As Classis GPT has a fixed Tone, verbosity & Style. Through GPT 4, Users can guide the AI model to write something in their defined tone and style.
The improved steerability in GPT-4 opens up new possibilities for fine-grained control. This ensures that the AI produces more relevant, accurate, and context-aware responses in various applications, making it a more versatile and reliable tool for users.
3- Risk & Mitigations
GPT 4 is now more secure than its previous version. The Open AI team has done great work here. Now AI model response tendency has been decreased by 80% for queries related to disallowed content & sensitive questions. This means that misuse chances of GPT 4 will be reduced.
4- Improved Behavior
GPT-4, similar to earlier versions, predicts the next word in a text using a mix of public and licensed data. This vast dataset comprises accurate and flawed math solutions, diverse reasoning levels, consistent and contradictory statements, and various ideologies and concepts.
The base model may produce diverse responses when asked a question, potentially deviating from user intent. To ensure alignment with user expectations, the model is fine-tuned using reinforcement learning with human feedback (RLHF) for more controlled behavior.
GPT-4 considerably mitigates hallucinations compared to earlier versions, showing consistent improvement. It scores 40% higher than GPT-3.5 on internal adversarial factuality assessments. However, GPT-4’s knowledge is limited to pre-September 2021 events, and it needs to learn from its experiences.
So, Using GPT 4 factual knowledge in high-risk areas still needs to review by a human before use.
How to Access GPT 4?
ChatGPT Plus subscribers can access GPT-4 on chat.openai.com, subject to a usage cap. For GPT 4 API, You can signup for the waitlist.
