What to look forward to
Open Athena will share the research, engineering, and organizational lessons behind Marin’s 535-billion-parameter model, trained on 18 trillion tokens in a record-setting live-streamed run. The program will feature Stanford professor Percy Liang, AI researcher David Hall, Databricks co-founder Andy Konwinski, and Marin researcher Will Held.
Inside the event
Marin started as an academic project with one full-time researcher, training medium-sized language models on Google’s TPU Research Cloud. This month, the team finished pre-training a 535B-parameter mixture of experts model on 18T tokens, using GPUs from the Huang Foundation, in the largest live-streamed pre-training run to date.
This required scaling everything: compute, data, focus, and people. We ran thousands of smaller models to understand scaling, built systems for turning trillions of raw tokens into training mixtures, learned how to train sparse models efficiently, built infrastructure for running reliably across large and heterogeneous clusters, and found people and organizations excited to support open development at this scale.
Open Athena is hosting this event at Laude Labs to share the research, engineering, and organizational work that went into scaling Marin, and what we've learned (and are still learning) from the run. Light bites and drinks will be served for the evening.
