The New ChatGPT update is mind-blowing: The GPT-4 is here!

ChatGPT 4

OpenAI has recently announced the launch of GPT-4, the newest and largest version of its language model. This new model is believed to exhibit “human level performance” on various professional tests, as it has been trained on a vast amount of data and possesses more weights in its model file than its predecessors. The approach used in developing GPT-4 involves scaling up to achieve better results, which many researchers in the field believe is responsible for recent advancements in AI.

To train GPT-4, OpenAI used Microsoft Azure, with Microsoft investing billions in the startup. Although the specific model size or hardware used in training it has not been revealed, it is known that the model was trained on thousands of supercomputers, which could cost tens of millions of dollars.

GPT-4 is expected to power many artificial intelligence demos in the coming weeks, and Bing’s AI chatbot is already using it, according to Microsoft. OpenAI claims that the new model will produce fewer factually incorrect answers and go off-topic less often. It will also perform better than humans on many tests, achieving scores at the 90th percentile on a simulated bar exam, the 93rd percentile on an SAT reading exam, and the 89th percentile on the SAT Math exam.

Although the difference between GPT-3.5 and GPT-4 may not be immediately noticeable during casual conversation, OpenAI claims that GPT-4’s superiority becomes evident when the conversation delves deeper. As artificial intelligence tasks become more complex, GPT-4 is expected to demonstrate greater reliability and creativity than its predecessor. OpenAI also provides test results to support this advancement, showing that GPT-4 outperforms its predecessor in almost every field.

However, OpenAI warns that GPT-4 is not perfect and is less capable than humans in many scenarios. The model still suffers from “hallucination,” or making up facts, and is not always factually reliable. It is prone to insisting that it is correct, even when it is wrong. OpenAI is working to address these limitations, such as social biases, hallucinations, and adversarial prompts.

The new model will be available to paid ChatGPT subscribers and as part of an API that programmers can integrate into their apps. OpenAI will charge approximately 3 cents for about 750 words of prompts and 6 cents for about 750 words in response.

In conclusion, the launch of GPT-4 represents a significant advancement in the development of AI and natural language processing. Although it has its limitations, the model’s ability to perform at or above human levels on standardized tests suggests that it has the potential to be a valuable tool for a wide range of applications, from chatbots to search engines and more. OpenAI is continuing to refine and improve its technology, and we can expect to see even more impressive strides in the field of AI in the future.
