I’m not sure about other methods, but AlphaFold does predict peptides in both cis and trans configurations. In a recent paper, Osnat Herzberg and John Moult show that it was pretty successful in predicting proline cis-peptides, among the novel structures in the CASP15 set of targets (https://www.pnas.org/doi/10.1073/pnas.2221745120).
For non-proline cis-peptides, I’m not aware of published work but Tristan Croll has shown me examples of correctly-predicted non-proline cis-peptides, including cases where some of the related structures in the PDB have an incorrect trans configuration. This implies that AlphaFold is not slavishly reproducing what it has seen during training.
