OpenAI’s ChatGPT-4 is the latest iteration of the groundbreaking Generative Pre-trained Transformer (GPT) series. Building on the success of its predecessors, GPT-4 offers enhanced capabilities, improved performance, and a more user-friendly experience. GPT-4 was publicly released on March 14, 2023, making it accessible to users worldwide. Let’s explore how to use ChatGPT-4, its new features, and more.

New Features of OpenAI's ChatGPT-4

OpenAI highlights three significant advancements in this next-generation language model: creativity, visual input, and longer context. According to OpenAI, GPT-4 demonstrates substantial improvements in creativity, excelling in both generating and collaborating with users on creative endeavors. Let’s see some of the top new features of ChatGPT-4.

Can Understand More Advanced Inputs

One of the major breakthroughs of GPT-4 lies in its enhanced capacity to comprehend intricate and nuanced prompts. OpenAI reports that GPT-4 showcases performance at equivalence with human-level expertise on diverse professional and academic benchmarks.

This achievement was demonstrated by subjecting GPT-4 to numerous human-level exams and standardized tests, including the SAT, BAR, and GRE, without any specific training. Remarkably, GPT-4 not only grasped and successfully tackled these tests, but it also consistently outperformed its predecessor, GPT-3.5, across all assessments.

GPT-4 boasts support for more than 26 languages, including less widely spoken ones like Latvian, Welsh, and Swahili. When assessed based on three-shot accuracy using the MMLU benchmark, GPT-4 surpassed not only GPT-3.5 but also other prominent LLMs such as PaLM and Chinchilla in terms of English-language proficiency across 24 languages.

Multimodal Functionality

In contrast to the previous version, ChatGPT, GPT-4 introduces a remarkable advancement in its range of multimodal capabilities. This latest model can now process not only text prompts but also image prompts.

This groundbreaking feature enables the AI to accept an image as input, interpret it, and explain it as effectively as a text prompt. The model seamlessly handles images of varying sizes and types, including documents that combine text and images, hand-drawn sketches, and even screenshots.

Enhanced Steerability

OpenAI further claims that GPT-4 exhibits a remarkable level of steerability. Notably, it has become stronger in staying true to its assigned character, reducing the likelihood of deviations when deployed in character-based applications.

Developers now have the ability to prescribe the AI’s style and task by providing specific instructions within the system message. These messages enable API users to customize the user experience extensively while operating within defined parameters. To ensure model integrity, OpenAI is also actively working on enhancing the security of these messages, as they represent the most common method for potential misuse.

Safety

OpenAI dedicated six months to enhancing the safety and alignment of GPT-4. According to the company, GPT-4 demonstrates significant improvements, with a reduction of 82% in the likelihood of generating inappropriate or prohibited content in response to requests.

Additionally, it exhibits a 29% increase in aligning with OpenAI’s policies when responding to sensitive inquiries and a notable 40% improvement in generating factual and accurate responses compared to its predecessor, GPT-3.5.

Enhanced Performance

In addition to human exam evaluations, OpenAI thoroughly assessed the model’s performance using established benchmarks specifically designed for machine learning models.

OpenAI asserts that GPT-4 showcases significant superiority over existing LLMs as well as many cutting-edge models. The benchmarks include reputable assessments like MMLU, WinoGrand, AI2 Reasoning Challenge (ARC), Drop, and HumanEval. Each of these tests focuses on assessing the distinct capabilities of the model.

How to Use ChatGPT-4

Accessing ChatGPT-4 requires a subscription to the premium edition of the website called ChatGPT+. To obtain a subscription, follow these steps:

Visit the ChatGPT website by going to https://chat.openai.com/.

If you already have access to ChatGPT+, you will be directed to ChatGPT-4 automatically.
If you don’t have the premium version, you need to upgrade by clicking on the “Upgrade to Plus'' option in the sidebar. It will cost $20 per month or BDT 2,141 ($1= 107.05).

Limitations of ChatGPT-4

Like its predecessors, GPT-4’s training data is restricted to information available until September 2021. Therefore, it may not provide an accurate output when newer information is required. However, users now have the option to supply GPT-4 with the missing information to enhance its responses.

While GPT-4 exhibits improved accuracy compared to GPT-3.5, it is not entirely immune to generating falsehoods or flawed logic. Although these occurrences are less frequent, it is essential for users to verify the output provided by GPT-4, regardless of how truthful it may appear.

Smaller companies may find it financially burdensome to implement powerful tools like ChatGPT Plus due to their scale of operations. An example is Latitude, a game developer that initially utilized an older version of GPT for its online role-playing game, AI Dungeon. As the game gained popularity, the associated AI costs skyrocketed, reaching nearly $200,000 per month to handle the high volume of user queries. To adapt, Latitude had to switch to a more cost-effective language software and introduce additional charges for advanced AI features to sustain its operations.
