What is CodonRoBERTa and how does it work?

CodonRoBERTa-large-v2 is a RoBERTa-based transformer trained on codon sequences, achieving perplexity 4.10 by learning species biases directly from data.

How much does it cost to train mRNA language models across 25 species?

About $165 in cloud GPU costs for 55 hours, producing four production models.

Will OpenMed's protein pipeline replace commercial codon optimization?

It matches performance at zero cost with open code, but needs more validation for clinical use — ideal for research now.
