@IlyasMoutawwakil what are your expectations for merging this PR? We're considering using transformers 4.57 for one of our testing pipelines, so having the corresponding support on optimum-intel's side would be a very good thing.

@CuriousPanCake my expectation is that it is good to go 😁
we have seen an occasional / non-consistent segfault with sam model (can't reproduce it locally and rerunning the test passes without a segfault) but it also started happening at the same time as the openvino 2025.4 release, i personally can't find a way to reproduce it locally and the issue happens randomly so, dunno what to do about that.
