An AI model is the underlying technology — the neural network trained on data (like GPT-4 or Claude). An AI product is the application built on top of a model (like ChatGPT, which is built on GPT-4, or Notion AI, which uses multiple models). When evaluating AI for your business, this distinction matters: you might use the same model through different products, and different products built on the same model can perform very differently depending on how they've been configured, fine-tuned, and integrated.
