The advancements in AI language models, such as ChatGPT and Dall-E, have impressed many with their capabilities. However, it’s important to note that both models are based on OpenAI’s GPT-3.x family of large language models. These models utilize deep learning techniques to generate text that resembles human language, based on input.
When GPT-3 was first introduced in 2020, it represented significant improvements over its predecessor, GPT-2. Now, GPT-4 is in development, and there is growing excitement surrounding the advancements it will bring. In this article, we will explore the potential improvements and differences between GPT-4 and its predecessor, GPT-3.
GPT-4, short for “Generative Pre-trained Transformer,” is a series of language processing models that continuously evolve and learn through training on vast amounts of data. Additionally, these models utilize technologies like Natural Language Processing (NLP) and Natural Language Generation (NLG) to better understand and replicate human language. GPT-4 is expected to replace GPT-3 and GPT-3.5 when it is released, which is predicted to be in late 2023.
When it comes to parameters, in an interview last year, Sam Altman, CEO of OpenAI, stated that GPT-4 will not be significantly larger than GPT-3. GPT-3 currently has 175 billion parameters, and while GPT-4 is expected to have slightly more, recent reports suggest that it could have as many as one trillion parameters. This significant increase in parameters could result in ChatGPT producing more accurate responses at a faster rate, but also increase the cost of running GPT-4 for OpenAI.
In terms of accuracy, GPT-4 is anticipated to bring a host of improvements to its ability to replicate human behavior and speech patterns in response to user prompts. Better optimization could mean that GPT-4 will be more adept at inferring human intentions, even in the presence of errors, than previous versions of GPT.
Additionally, with OpenAI’s focus on constantly improving algorithms like Reinforcement Learning from Human Feedback (RLHF), GPT-4 has the potential to better implement this technique, which involves human trainers helping to fine-tune AI models through supervised fine-tuning. This could lead to a reduction in the likelihood of GPT/ChatGPT producing toxic or biased content, as well as fewer instances of misinformation.
It’s worth noting that OpenAI has not disclosed many details about GPT-4, so much of the information circulating the internet is speculative. Therefore, it’s important to approach this information with a degree of caution.
