CausalMix: Data Mixture as Causal Inference for Language Model Training

We unpacked CausalMix, the paper that treats data‑mixing as a causal inference problem. Cooper pulls the product angle—why it matters for shipping models, and Miles dives into the DML‑based plumbing and the trade‑offs. We talk about how it tackles shifting data pools, the CATE forest, and why the authors think it can generalize to larger models. A touch of banter and a light‑hearted sign‑off close the episode.
