Llama 2-13B is an AI model developed by Meta AI (United States), first published in July 2023. It works in the language domain, on tasks such as language modeling.
Training it took an estimated 1.6×10²³ FLOP of compute (estimation method: hardware,operation counting). The model has 13,000,000,000 parameters. It was trained on roughly 2T datapoints. Training ran on NVIDIA A100 SXM4 80 GB. The compute alone is estimated at $235K in 2023 dollars.
Access: Open weights (restricted use). Its weights are openly available. The reference paper has 16,911 citations. Epoch AI rates the confidence of this record as confident.
