When using a seed with the Large Biomes generation setting in 1.18 pre-release 1, it will not match the biome placement of the same seed's default generation. The biomes on the Large Biomes world seem to indeed be larger than usual(though there is no way to compare directly), but the terrain and biomes will be completely different compared to the default world generation using the same seed. The player will typically spawn in completely different biomes when using the same seed to start new worlds with the default and large biome settings.

How to Reproduce:
Create a world using default generation settings.
Create a Large Biomes world using the same seed as the world with default settings.
Compare the biome placement of each.
The biomes on the Large Biomes world seem to indeed be larger than usual(though there is no way to compare directly), but the terrain and biomes will be completely different compared to the default world generation using the same seed. The player will typically spawn in completely different biomes when using the same seed to start new worlds with the default and large biome settings.
Expected Result: The Large Biome world generated from the same seed as a default world would have the same biome placement as its default generation, only larger. This is how Large Biomes functions in 1.17, 1.16, etc.

This being WAI also makes no sense as it used to be a 4:1 scale of the world but is now completely different. In the current state, the world generation has parity with bedrock, but not within JAVA anymore. I am holding out hope that this will get fixed as it renders the world seed completely useless and forces me to either play without the setting or not at all.
This is probably caused by the change that the noise sources now get initialized with an MD5 hash of the noise generator name, which are different for large biomes (e.g. "minecraft:temperature" and "minecraft:temperature_large"). In previous versions the layered biome generation was (almost) just an up-scaling of the normal generation.
