GPT-2 (1.5B, Curriculum Learning 45K) is an AI model developed by Microsoft (United States), first published in August 2021. It works in the language domain, on tasks such as language modeling/generation.
Training it took an estimated 2.4×10²¹ FLOP of compute (estimation method: comparison with other models,hardware,operation counting). The model has 1,500,000,000 parameters. It was trained on roughly 157B datapoints. Training ran on 128 NVIDIA V100 for about 155 hours.
Access: Unreleased. Its weights are not openly released. The reference paper has 55 citations. Epoch AI rates the confidence of this record as likely.
