GPT-4: Features, Capabilities, Pricing and Examples

An AI that chats just like a close friend, decodes images, writes code and explains live sports in real time. It is all possible with GPT-4. OpenAI's chatbot is powered by the GPT-4 and GPT-4o models. It was launched in March 2023. This technology blends text, vision and voice to create seamless and human-like interactions. ChatGPT provides everything- even if you are a student nailing homework, a coder squashing bugs or a business boosting efficiency.

This guide will help you in understanding what is GPT-4, its visionary goals and many more like its features, use cases, limitations and pricing. Let's begin.

What is GPT-4?

GPT-4 is essentially ChatGPT enhanced with GPT-4. It is OpenAI's fourth-generation Generative Pre-trained Transformer model. GPT-4 is a multimodal AI that processes both text and images to give intelligent text responses as output. It was trained on massive datasets from the internet and licensed sources by using techniques like reinforcement learning from human feedback (RLHF). It is to align with user needs and safety guidelines.

It is not like earlier models. It excels in complex reasoning, creativity and handling nuanced instructions. For instance- it can analyze an image of a menu in another language, translate it and suggest dishes based on dietary preferences. As per OpenAI's official research, GPT-4 achieves human-level performance on benchmarks like the Uniform Bar Exam and it scores in the top 10%. It is a huge jump from GPT-3.5's bottom 10%.

In 2024, OpenAI introduced GPT-4o ('o' for omni), which builds on GPT-4 by adding real-time voice, audio and video capabilities. By April 2025, OpenAI announced GPT-4 would be replaced in ChatGPT by GPT-4o by month's end to make advanced features more accessible. Now, free users get GPT-4o with limits and paid users get expanded access. This evolution keeps this model relevant for tasks from casual chats to professional analysis.

The Vision Behind GPT-4

OpenAI's vision for ChatGPT-4 centers on scaling AI safely and accessible to benefit humanity. They rebuilt their deep learning infrastructure with Azure to create a supercomputer for stable training. This helps with the prediction feature. OpenAI can accurately forecast GPT-4's performance before full training.

The core vision also includes safety and alignment. After six months of iterative improvements that include adversarial testing and RLHF, GPT-4 reduces harmful outputs by 82% and boosts factuality. One of their main goals was to create an AI that's steerable, refuses unsafe requests and evolves with user feedback. OpenAI also uses open-sourced tools like Evals for community-driven benchmarks.

In the long run, the vision also includes multimodal expansion. GPT-4o's real-time voice and vision aim to make AI feel natural like explaining rules during a live sports stream.

Key Features of GPT-4

This model packs innovative features that set it apart. These features make GPT-4 versatile for beginners and experts alike. Here is a breakdown in bullet points for easy scanning:

• Multimodal Input:

It accepts text and images. It can describe a photo, solve diagram-based questions or summarize screenshots.

• Extended Context Window:

It can handle up to 8,192 tokens (about 6,000 words). GPT-4 Turbo extends to 128K for longer conversations.

• Steerability:

It uses system messages to customize tone. It responds as a Socratic tutor who asks guiding questions instead of giving answers.

• Improved Language Support:

It outperforms in 24 of 26 languages tested to include low-resource ones like Latvian or Swahili.

• Voice and Vision in GPT-4o:

It can do real-time audio processing and converse naturally. It can explain videos or translate spoken languages across 50+ options.

• Data Analysis Tools:

Upload charts or datasets to get insights, create visualizations or run code interpretations.

• Plugin Integration:

It connects to external tools for browsing, image generation (via DALL-E) or code execution.

Capabilities of GPT-4

OpenAI tested GPT-4 on a variety of benchmarks. It includes challenging exams designed for humans. They used the most recent publicly available tests for Olympiad and AP free-response questions. For other cases, they relied on 2022-2023 practice exam editions. The model was not specifically trained for these exams. Although small questions had been part of its training data, the results are still considered a fair representation of its capabilities. For more representative data you can see the official technical report.

OpenAI also evaluated GPT-4 on traditional benchmarks commonly used for testing machine learning models.
