The field of artificial intelligence has witnessed significant strides, and OpenAI has been at the forefront of developing cutting-edge language models. In their latest innovation, OpenAI introduces GPT-4, boasting remarkable improvements over its predecessor, GPT-3.5. You can start using the latest version of OpenAI’s large language model (LLM) GPT-4 as soon as it was launched. To gain access to the text-input feature of the model through OpenAI, you need to subscribe to ChatGPT Plus, which ensures that you can utilize the language model for a monthly fee of $20.
This article aims to delve deep into the enhancements and features of GPT-4, providing a comprehensive analysis and evaluation of its capabilities. By comparing GPT-4 with GPT-3.5, we will explore whether the subscription fee for ChatGPT Plus truly justifies its value.
The Power of Parameters
The parameter count in GPT-4 stands as a testament to its enhanced capabilities. Although the exact number of parameters remains undisclosed, Andrew Feldman, CEO of AI company Cerebras, estimates that GPT-4 has been trained with around 100 trillion parameters. This remarkable increase in parameters sets it apart from GPT-3.5, which relied on 175 billion parameters. The greater parameter count empowers GPT-4 to capture intricate relationships between words and concepts, leading to more refined responses.
GPT-4 introduces a revolutionary concept—multimodal models. While GPT-3.5 solely focused on processing text data, GPT-4 embraces the ability to analyze both text and image data concurrently. This new dimension enables GPT-4 to accept images as input and generate relevant textual responses. For example, when presented with an image of a refrigerator’s contents, GPT-4 can suggest recipes based on the recognized ingredients. It’s important to note, however, that ChatGPT Plus, the subscription service, does not include image-based responses.
Expanding Memory Horizons
One of the notable advancements in GPT-4 lies in its extended short-term memory capabilities. While GPT-3.5’s short-term memory is limited to approximately 8,000 words, GPT-4 can retain and process around 64,000 words in its short-term memory. Furthermore, GPT-4 can extract text from web pages when provided with a URL in the prompt, augmenting its knowledge beyond the confines of its training data.
GPT-4 significantly enhances its multilingual capabilities, making it a versatile language model. It can proficiently process 25 languages in addition to English, including French, German, and Spanish. This expansion broadens the accessibility and usability of GPT-4 for users worldwide, facilitating effective communication in diverse linguistic contexts.
GPT-4 introduces enhanced “steerability,” allowing users to exercise greater control over its responses by specifying a preferred “personality.” This unique feature empowers users to instruct GPT-4 to generate answers and interact as if it embodied a specific persona. Whether it’s a pirate, a professor, or any other character, GPT-4 adapts its responses accordingly, providing a more engaging and tailored experience.
Delving into Search Capacities
Although GPT-4’s Language Model (LLM) is limited to training data up to September 2021, it offers a notable capability—Bing-based internet search. Users can instruct ChatGPT-4 to search the web, leveraging Bing’s search engine to acquire more up-to-date and relevant information. This feature provides a means to access real-time data and insights, enhancing the responsiveness and timeliness of GPT-4’s answers. However, it’s important to note that this search functionality is still in beta and may have occasional limitations.
Plugins: Unleashing the Potential
OpenAI introduces plugins as a beta feature, allowing both OpenAI and third-party developers to integrate external application programming interfaces (APIs) with ChatGPT-4. This innovation opens up endless possibilities for expanding GPT-4’s capabilities and intelligence. Developers can create plugins to seamlessly integrate specialized functionalities into ChatGPT-4, such as travel planning with Expedia and Kayak or extracting information from PDF documents using the Ask Your PDF ChatGPT Plugin. These plugins unlock new realms of productivity and efficiency for users.
Performance Redefined: Accuracy and Factual Responses
OpenAI claims that GPT-4 demonstrates substantial improvements in performance compared to GPT-3.5. It has achieved higher scores on various exams, including the LSAT, SAT, Uniform Bar Exam, and GRE. OpenAI further asserts that GPT-4’s responses are 40% more likely to provide factual and accurate information. This progress signifies the refined training and enhanced accuracy of GPT-4.
While GPT-4 exhibits impressive advancements, it’s crucial to acknowledge its limitations. GPT-4 remains an AI language model and does not possess human-level intelligence. Its performance on the AP English Language and Composition test, for example, only garners a score of 2, which is insufficient for academic or professional purposes. GPT-4’s strength lies in its ability to generate text based on statistical probabilities derived from its training data, rather than in-depth understanding or critical analysis.
In conclusion, GPT-4 represents a significant leap forward in the evolution of OpenAI’s language models. With enhanced parameters, multimodal capabilities, extended memory, multilingual support, steerability, search capacities, and the potential of plugins, GPT-4 outshines its predecessor, GPT-3.5. ChatGPT Plus, the subscription service granting access to GPT-4, offers users a powerful tool to augment their work. However, it’s important to recognize that GPT-4 should be viewed as a valuable aid rather than a complete replacement for human expertise.
