GPT-2 (774M) is an AI model developed by OpenAI (United States), first published in February 2019. It works in the language domain, on tasks such as language modeling/generation. It counts among the frontier models: the systems trained with the most compute of their moment.

Training it took an estimated 5×10²¹ FLOP of compute. The model has 774,000,000 parameters. It was trained on roughly 10.7B datapoints. The compute alone is estimated at $19K in 2023 dollars.

Access: Open weights (unrestricted). Its weights are openly available. The reference paper has 26,463 citations. Epoch AI rates the confidence of this record as speculative.
