AI2 Open-Sources Olmo-core Training Library for OLMo Models
Teams that want full control over pretraining can now start from AI2's scripts instead of assembling their own distributed stack, which cuts weeks of infrastructure work. It matters for open-source researchers comparing OLMo against Llama or Qwen, since OLMo's data and training code are fully reproducible. Practitioners can clone the repo and run the provided annealing scripts on their own data.
