Model organism interpretability depends strongly on training methodology, with integrated training yielding less interpretable MOs than post-hoc SFT or DPO.
Emergent abilities are capabilities present in large language models but absent in smaller ones and cannot be predicted by extrapolating smaller model performance.
PRISM shows that prompt engineering and selective ICL often outperform complex multi-agent systems on financial retrieval benchmarks while remaining training-free and achieving competitive NDCG@5 scores.
