[Prototype] torch.compile(dynamic=True)
Experimental support for PT2 compilation with dynamic shapes is available in this release. Inference compilation with inductor for simple models is supported, but there are a lot of limitations:

Training available in a future release (This is partially fixed in nightlies!)
Minifier available in a future release.
It is easy to end up in a situation where the dimension you wanted to be dynamic gets specialized anyway. Some of these issues are fixed in nightlies, others are not.
We do not appropriately propagate Inductor guards to the top-level, this is tracked at #96296.
Data-dependent operations like nonzero still require a graph break.
Dynamic does not work with non-standard modes like reduce-overhead or max-autotune.
