The baby horse model in the latest snapshot of Java Edition is larger than the one in Bedrock Edition.
I have confirmed this by comparing the .geo model in the bedrock-samples repository’s preview branch against an extracted entity model from 26.1-snapshot-10, plus viewing them in-game.
Testing in Blockbench, I was able to match the approximate size of the .geo model by shrinking the Java baby horse model to ~0.9093.
