Handwritten digit recognition network is an AI model developed by AT&T (United States), first published in November 1989. It works in the vision domain, on tasks such as digit recognition. It counts among the frontier models: the systems trained with the most compute of their moment.

Training it took an estimated 1.8×10¹¹ FLOP of compute (estimation method: hardware). The model has 2,578 parameters. It was trained on roughly 9.8K datapoints.

Epoch AI rates the confidence of this record as confident.
