GPT

GPT is a family of large language models developed by OpenAI, most widely known as the technology behind ChatGPT. The model line has undergone multiple updates, with OpenAI periodically retiring older versions and migrating users to newer iterations.

Recent specialized applications include GPT-Rosalind, developed through OpenAI's biodefense unit for pharmaceutical and life sciences research, reflecting the trend toward domain-specific AI systems. To better evaluate frontier AI capabilities, OpenAI introduced LifeSciBench, a benchmark designed to measure how AI systems handle real-world research tasks, moving beyond simple question-answering.

In the broader landscape, GPT operates as one of several frontier AI models competing on performance, cost, and specialized capabilities alongside models from other major AI developers.
