Title: An Extensive Handbook on ChatGPT AI Models for 2025
OpenAI’s ChatGPT has quickly transformed into one of the most robust and adaptable AI tools accessible to the general public. Nevertheless, with the launch of various new models, features, and subscription options, deciphering which ChatGPT version performs which functions has become increasingly intricate. Whether you are a casual user, a developer, or a business expert, this guide elucidates the present array of ChatGPT models and assists you in navigating the choices available in 2025.
Overview: Why Such a Variety of Models?
In 2025, OpenAI unveiled a multitude of new ChatGPT editions, each catering to specific tasks like reasoning, coding, or image creation. Unfortunately, the naming system—such as GPT-4o, o3, o4-mini, and GPT-4.5—has led to user confusion. Even OpenAI CEO Sam Altman has recognized this issue and has committed to introducing a more cohesive naming structure later this year.
In the meantime, here’s a summary of what’s on offer by tier.
