Quick question about MP-0 and MP-0b

[turbosonics]

Just quick question from pure curiosity, what is the difference between the MP-0 and MP-0b? I run some tests, their results are very similar but slightly different, so I was wondering what is difference between two. I read Arxiv paper for MP-0 but never saw any documentation for MP-0b...

Thanks

Hey @turbosonics , MP-0b is slightly improved version of the medium and small model, adding better treatment of repulsion interactions and better referencing of the isolated energies. It is recommended to use these models for finetuning.

@ilyes319 Hi, thanks for the answer, may I ask a little more detail? Does the 'large', 'medium', and 'small' option differ by size of MP AIMD data? Or some other hyperparameters involved?

By hyper-parameters, I point you to preprint where we explain this.
