'''GPT-4''' (Generative Pre-trained Transformer 4) is a multimodal artificial intelligence model developed by [[OpenAI]]. Released on March 14, 2023, GPT-4 is capable of understanding and generating human-like text, as well as processing images as input.

GPT-4 is part of the Generative Pre-trained Transformer (GPT) family and represents a significant advancement over its predecessor, [[GPT-3.5]], with improved reasoning, accuracy, and contextual understanding.

== Overview ==
GPT-4 is designed to perform a wide range of natural language processing (NLP) tasks, including:
* Text generation
* Question answering
* Code generation
* Translation
* Summarization

Unlike earlier models, GPT-4 introduced multimodal capabilities, allowing it to interpret both text and image inputs.

== Features ==
=== Multimodal Capabilities ===
GPT-4 can analyze images and provide textual descriptions or answers based on visual input.

=== Improved Reasoning ===
The model demonstrates stronger logical reasoning and problem-solving abilities compared to previous versions.

=== Extended Context Window ===
GPT-4 supports larger context windows, enabling it to process longer documents and maintain coherence over extended conversations.

=== Safety Improvements ===
OpenAI implemented enhanced alignment and safety measures to reduce harmful or biased outputs.

== Applications ==
GPT-4 is used in a variety of applications, including:
* Chatbots and virtual assistants (e.g., [[ChatGPT]])
* Content creation tools
* Programming assistance
* Educational platforms
* Customer support automation

== Reception ==
GPT-4 received widespread attention for its advanced capabilities. Many experts noted its improved performance on standardized tests, including law and medical exams. However, concerns remain regarding bias, misinformation, and ethical implications of AI systems.

== Limitations ==
Despite its advancements, GPT-4 has several limitations:
* May produce incorrect or fabricated information ("hallucinations")
* Limited real-time knowledge updates
* Can reflect biases present in training data

== Successors ==
Following GPT-4, OpenAI introduced newer models such as:
* [[GPT-4o]] – optimized for speed and multimodal interaction
* [[GPT-5]] – further improvements in reasoning and efficiency
