Olmo-core 3: Ai2 Speeds Up Mixture-of-Experts Training

The Allen Institute for AI (Ai2), a Seattle-based AI research organization, released a new framework on Thursday for training large language models built on the mixture-of-experts design. The framework, called Olmo-core 3, is meant to push MoE training to the trillion-parameter scale while keeping compute use efficient and costs under control.

The code and related systems are available now on GitHub for developers and the open-source community.

Why mixture-of-experts models are hard to train

A dense model uses all of its parameters for every token it processes. A token is a small piece of text, often a word or part of a word, that a model reads or generates. Parameters are the internal values that determine how the model behaves.

Ataraxos AI Beats Stratego Legend Pim Niemeijer 15-1

Stratego was one of the few major competitive board games where humans still had the edge over machines. That may now be over. A research team from Carnegie Mellon University, New York University, Stanford University and MIT has built Ataraxos, a Stratego AI that clearly beat the most successful player in the game's history. According to the team, training cost less than $8,000.

The work is published in Nature. As far as the authors know, Ataraxos is the first AI to reach superhuman level in Stratego.

A one-sided match against the best

In an official 20-game series, Ataraxos played Dutch player Pim Niemeijer. The final score was 15 wins, four draws and one loss for the AI.
