Marc Marone: “Open data was really really important for our work on knowledge cutoffs. We needed fully open data to understand recency and staleness in the dataset as a whole, rather than just for one specific resource or part of a dataset.”

@shubhramishra.bsky.social: “Imagine you want to explore how addition is learned as a model is trained. If a model has 100 checkpoints, you could take checkpoint #10, #20, ... and the final model, and run inference with those 10 ‘models.’ Olmo provides a ton of checkpoints.”

6/ 🪞 Two sentences can mean the same thing (“A is B” and “B is A”), but not always to LLMs, depending on their training data makeup. Researchers proved this using Olmo’s open data + identified fixes.

2/ 🤓 Thanks to Olmo being fully open, researchers at KAIST could watch it learn in real time. They slipped in a new fact during training and watched the model’s confidence in recalling that fact later. More varied exposure made the info stick better.

1/ 🧽 Can AI “forget”?
Unlearning = removing a fact from a model without retraining everything or breaking other skills. Using Olmo + our open Dolma corpus, researchers found the more often a fact appears in training, the harder it is to erase.
