However, safety concepts are rare in typical data, and it is unclear which SAE setups produce fine-grained safety features. Explaining every feature is also expensive. Safe-SAIL is a three-stage pipeline (SAE training… 2. **[Why Steering Works: Toward a Unified View of Language Model Parameter Dynamics](https://md.research.elamur.ai/free/en/papers/xu-2026-why-steering-works-unified-view/)** *(2026 · 1 citation)* Methods for controlling LLM behaviour are usually studied separately, with different assumptions and evaluation setups. 3. **[Perplexity-Aware Data Scaling Law: Perplexity Landscapes Predict Performance for Continual Pre-training](https://md.research.elamur.ai/free/en/papers/liu-2026-perplexity-aware-data-scaling-law/)** *(2026)* Continual pre-training (CPT) adapts general LLMs to specialised domains such as medicine. Simply adding more domain tokens quickly stops paying off, because classical scaling laws treat every token as equally useful. This paper proposes a perplexity-aware data scaling law.
