OPT
The Open Pre-trained Transformer (OPT) models are a collection of large language models with parameters ranging from 125 million to 175 billion. These models were trained to perform zero- and few-shot learning, which has demonstrated significant capabilities across various language tasks. OPT models are designed to be a more accessible alternative to other large-scale language models, such as GPT-3, which often requires substantial resources to replicate due to their computational costs. OPT also stands out for its smaller environmental footprint during development, requiring only one-seventh of the carbon footprint compared to GPT-3. Researchers behind OPT have taken care to share their models fully and responsibly, providing not only the model weights but also the logbook of their development challenges and the code necessary for experimentation.
