Originally released with limited capabilities, Bard has become increasingly capable in the second half of 2023, most recently gaining the ability to help write and debug code. Bard builds upon Google's research in the transformer architecture, Gopher scaling, Chinchilla compute-optimal scaling, and Sparrow dialogue finetuning.
