GPT-3, or Generative Pre-trained Transformer 3, is a large language model developed by OpenAI with a staggering 175 billion parameters, making it one of the largest AI models to date 12. This scale allows it to perform a wide range of tasks, from generating human-like text to translating languages and composing creative content 29. GPT-3 encompasses a family of models varying in size, all underpinned by a transformer architecture 1. Although initially accessible to developers broadly, Microsoft now holds exclusive licensing rights to its core technology, though OpenAI continues to provide API access 43. Despite its impressive capabilities, GPT-3 has faced criticism regarding biases arising from its training data and its inability to truly understand content, issues that subsequent models aim to resolve 210.
