  Large language models, pivotal in artificial intelligence, find diverse
applications. ChatGPT (Chat Generative Pre-trained Transformer), an OpenAI
creation, stands out as a widely adopted, powerful tool. It excels in chatbots,
content generation, language translation, recommendations, and medical
applications, due to its ability to generate human-like responses, comprehend
natural language, and adapt contextually. Its versatility and accuracy make it
a potent force in natural language processing (NLP). Despite successes, ChatGPT
has limitations, including biased responses and potential reinforcement of
harmful language patterns. This article offers a comprehensive overview of
ChatGPT, detailing its applications, advantages, and limitations. It also
describes the main advancements from GPT-3 to GPT-4 Omni, comparing them with
other LLMs like LLaMA 3 and Gemini. The paper underscores the ethical
imperative when utilizing this robust tool in practical settings. Furthermore,
it contributes to ongoing discussions on artificial intelligence's impact on
vision and NLP domains, providing insights into prompt engineering techniques.
