## Model

### ESMCrystal_t6_8M_v1

ESMCrystal_t6_8M_v1 is a state-of-the-art protein crystallization prediction model finetuned on [esm2_t6_8M_UR50D](https://huggingface.co/facebook/esm2_t6_8M_UR50D), 
having 6 layers and 8M parameters with the size of [approx. 31.4MB](https://huggingface.co/jaykmr/ESMCrystal_t6_8M_v1/blob/main/pytorch_model.bin)
using transfer learning to predict whether an input protein sequence will crystallize or not.
