- R · What Makes It Special
- Meta AI's OPT (Open Pre-trained Transformers, May 3, 2022), decoder-only language models from 125M to 175B parameters trained on publicly available data; OPT-175B is comparable to GPT-3 while needing 1/7th the carbon footprint to develop. Meta shared OPT-175B with researchers under a noncommercial license, calling it the first release at that scale to include both the trained model and the code to train and use it, fully released the smaller models, and published its training logbook.
