All-attention network + adaptive span is an AI model developed by Facebook AI Research (United States and France), first published in July 2019. It works in the language domain, on tasks such as language modeling/generation.
Training it took an estimated 1.2×10¹⁹ FLOP of compute (estimation method: hardware,operation counting). The model has 133,000,000 parameters. It was trained on roughly 103M datapoints. Training ran on 64 NVIDIA V100 for about 24 hours.
Access: Unreleased. Its weights are not openly released. The reference paper has 156 citations. Epoch AI rates the confidence of this record as likely.
