mbart-large-50-khm-32768

This model is a 36.42% smaller version of facebook/mbart-large-50 optimized for Khmer language via vocabulary size reduction using the trimming method.
This trimmed model should perform similarly to the original model with only 32,768 tokens and a much smaller memory footprint. However, it may not perform well for other languages as tokens not commonly used in the selected languages were removed from the vocabulary.
