Open Athena @openathena.ai · 03/09/2026
A year ago, Marin had one FTE. Recently, the ten-person team launched a 535 billion parameter MoE model. In the Marin 535B-A23B launch note, David Hall @dlwh.bsky.social notes it's going "almost boringly well." Thank you to our colleagues, partners, and advisors for making this possible. bit.ly/535b

A look back at Marin's first year at Open Athena and forward at the 535B-A23B hero run, the largest model the team has ever trained.

Excited to share MarinDNA, a 1B gLM that rivals Evo 2 40B on variant effect prediction while being 2,330x faster. With @eczech0.bsky.social, we built around a standard Transformer so we could reuse LLM infra and methods while focusing on data curation and scaling. openathena.ai/blog/marin-d... 🧵

Here's the tale of how @jder.bsky.social and I scaled Samudra, a neural ocean emulator capable of predicting 8 years of the ocean on a single GPU, to operate at a full 1/4° resolution (16x the size in bytes). It was quite a humbling process.

@runsascoded.com updated his visualization, showing the efficiency of different modes of transit between NYC-NJ. Lincoln tunnel bus lane is the winner - and it only operates for 3 hrs a day! Investment in private vehicle infrastructure, is not a good use of state or city resources. hbt.hccs.dev

1 bus lane (Lincoln Tunnel) moves 5x as many people per hour as 5 car lanes combined (Lincoln + Holland Tunnels) github.com/hudcostreets...
