Variational (untied weights, MC) LSTM (Large) is an AI model developed by University of Cambridge (United Kingdom), first published in December 2015. It works in the language domain, on tasks such as language modeling.

Training it took an estimated 5.9×10¹⁵ FLOP of compute (estimation method: operation counting). The model has 66,000,000 parameters. It was trained on roughly 929K datapoints.

Access: Unreleased. Its weights are not openly released. The reference paper has 1,838 citations. Epoch AI rates the confidence of this record as confident.
