Megatron-LM (355M) is an AI model developed by NVIDIA (United States), first published in September 2019. It works in the language domain, on tasks such as language modeling/generation.
Training it took an estimated 3.4×10²⁰ FLOP of compute (estimation method: operation counting). The model has 355,000,000 parameters. It was trained on roughly 46.4B datapoints.
Access: Open weights (unrestricted). Its weights are openly available. The reference paper has 2,766 citations. Epoch AI rates the confidence of this record as confident.
