GPT-4.1 makes ChatGPT smarter, faster, and more useful for paying users, especially coders

Elyse Betters Picaro / ZDNET OpenAI is now bringing GPT-4.1 to the Plus, Pro, and Team tiers of ChatGPT. GPT-4.1 was previously available only to API users. Since I'm throwing a whole lot of buzzwords at you, let's spend a minute deconstructing all these terms. GPT-4.1 is a large language model (LLM). It's the actual code that is the AI. Think of it as an engine in your car. A more powerful engine might have more vroom, but even a less powerful engine will move the car. Each of the GPT versions refers to AI models with more or less power. ChatGPT is the chat interface. It's the software that takes in your prompts, sends them to the large language model, and shows you the results. In our analogy, ChatGPT is the car, with GPT-4.1 (or GPT-4o, or GPT-3.5) being the engine. API (or application programming interface) is the way programs communicate with other programs. In the case of GPTs, it's how programs by many companies can call on an LLM to get results. A very rough analogy is the ... Read full article.
