Since its debut as an experimental prototype in late 2022, OpenAI's ChatGPT quickly transformed into an indispensable app for millions, revolutionizing the way people interact with technology. The emergence of large language models (LLMs) like ChatGPT has not only reshaped consumer habits but also ignited a fierce competition among tech companies eager to develop their own conversational AI solutions. The tech landscape, once dominated by traditional software, is now witnessing a rapid evolution as innovators strive to harness the potential of AI. With the remnants of the old tech era still visible, the industry is racing forward into a new age defined by intelligent, user-friendly applications.
