2) Characterizing Narrative Content in Web-scale LLM Pretraining Data, by @teagrjohnson.bsky.social, @elliottash.bsky.social, @andrewpiper.bsky.social, @mariaa.bsky.social arxiv.org/abs/2606.19468 Why: annotation and analysis of narrative features across the pretraining data (…
- A new arXiv preprint introduces NarraBERT, a RoBERTa-based classifier, and applies it to 3 million passages from the 3-trillion-token Dolma corpus.
- The framework operationalizes three narrative elements, agency, setting, and events, across 11 interpretable dimensions, trained on 400 annotated passages.
- The authors report narrative qualities are unequally distributed across pretraining sources and topics in ways current curation practices do not measure.

An incomplete list: 1) Explaining Attention with Program Synthesis, by Amiri Hayes, @belindazli.bsky.social and arxiv.org/abs/2606.19317 Why: LMs can generate code that can explain/replace attention heads! 🤯 (Program synthesis 🤝 Interpretability)
- Under 1,000 LM-generated programs reproduce attention patterns in GPT-2, TinyLlama-1.1B and Llama-3B with above 75% average IoU on TinyStories.
- Replacing 25% of attention heads with the synthesized programs raised average perplexity by only 16% while keeping downstream question-answering performance.
- The pipeline computes a head's attention matrices, prompts a pretrained LM to write Python that reproduces them, then re-ranks by held-out accuracy.
4) Why Larger Models Learn More: Effects of Capacity, Interference, and Rare-Task Retention arxiv.org/abs/2605.29548
- The paper argues power-law scaling already implies a larger model will learn parts of the data distribution a smaller model cannot, even with infinite training data.
- Pretraining experiments on OLMo models from 4M to 4B parameters found only the larger models learned the infrequent and complex tasks.
- The proposed mechanism is reduced gradient interference: weaker common-task updates leave rare-task features intact in larger models.
Does anyone know why MASS (arxiv.org/pdf/1905.02450) didn't take off, while BART did? (OK maybe no one remembers BART today, but it was popular around 2019-2022)

Recent commentary
Tip on reviewing ARR papers in 2026: - Check the references FIRST. I wasted 40 minutes reviewing a paper before realizing the references were LLM-generated.
I'm so tired of seeing LLM-generated reviews. They just wasting all our time. If this continues, "peer review" will mean nothing
It was a pleasure to moderate the panel at the ACL 2026 SRW: "The next big questions in NLP: What should students work on?" Huge thanks to our panelists, @boydgraber.bsky.social, @igurevych.bsky.social, Preslav Nakov and Yulia Tsvetkov for their thoughtful answers and helpful advice! Takeaways 👇
