What is CodonRoBERTa and how does it work?

CodonRoBERTa-large-v2 is a RoBERTa transformer trained on codon sequences, predicting optimal DNA for protein expression. It beats baselines on perplexity (4.10) and CAI (0.40), conditioned for 25 species.

How much does it cost to train mRNA language models like this?

OpenMed trained four multi-species models in 55 GPU-hours for $165 on A100s. Scalable to anyone's cloud budget.

Will OpenMed's pipeline speed up drug discovery?

Absolutely—end-to-end from protein concept to DNA in hours, open-source. Democratizes optimization for therapies, vaccines.
