TD-Gammon is an AI model developed by IBM (United States), first published in May 1992. It works in the games domain, on tasks such as backgammon. It counts among the frontier models: the systems trained with the most compute of their moment.

Training it took an estimated 1.8×10¹³ FLOP of compute (estimation method: third-party estimation,operation counting,hardware). The model has 25,000 parameters. It was trained on roughly 6.3M datapoints.

The reference paper has 1,344 citations. Epoch AI rates the confidence of this record as speculative.
