RT by @huggingface: A new foundation model that reads and generates DNA sequences was just released…

TL;DR - MarinDNA, a 1B-parameter genomic language model that reads and generates DNA sequences, was released on Hugging Face with a demo space. It matters because it reportedly matches Evo 2 40B on variant effect prediction while being ~2,330x faster, making genomic foundation models far cheaper to run.

• 1B-parameter gLM claimed to rival the 40B Evo 2 on variant effect prediction at roughly 1/2,330th the compute cost.
• Built on a standard Transformer architecture specifically so existing LLM infrastructure, tooling, and training methods could be reused directly.
• The team (Gonzalo Benegas, with @eczech0) attributes gains to data curation and scaling rather than novel architecture.
• Released openly on Hugging Face (marin-dna) with an interactive demo space; detailed writeup on the OpenAthena blog. Benchmark numbers are from the authors' announcement and are not independently verified here.
