+This script is used to get the list of folders under `tests/models` and split the list into `NUM_SLICES` splits.
+The main use case is a GitHub Actions workflow file calling this script to get the (nested) list of folders allowing it
+to split the list of jobs to run into multiple slices each containing a smaller number of jobs. This way, we can bypass
+the maximum of 256 jobs in a matrix.
+
+See the `setup` and `run_models_gpu` jobs defined in the workflow file `.github/workflows/self-scheduled.yml` for more
+details.
+
+Usage:
+
+This script is required to be run under `tests` folder of `transformers` root directory.
+
+Assume we are under `transformers` root directory:
+```bash
+cd tests
+python ../utils/split_model_tests.py --num_splits 64
+```
