draft May 13, 2026 ·OLMo-3-7B (base + post-trained variants), Apertus-8B (replication)
Model Spec midtraining shapes which value the model generalizes to from identical alignment data, and reduces agentic misalignment from 54–68% to 5–7% on Qwen2.5/3-32B without CoT supervision
draft May 3, 2026 ·Llama-3.1-8B, Qwen2.5-32B-Instruct, Qwen3-32B
Six narrowly misaligned fine-tunes of Qwen 2.5 32B split into coherent-persona models (harmful behavior + self-reported misalignment) and inverted-persona models (harmful behavior + self-reported alignment)
draft Apr 30, 2026 ·Qwen2.5-32B-Instruct, Llama-3.1-70B-Instruct
Introspection adapter — single LoRA jointly trained across labeled fine-tunes — reaches state-of-the-art 59% on AuditBench (vs. 53% next-best, 44% best white-box); verbalization scales with model size and training-data diversity but explicitly elicits a latent capacity rather than teaching a new one
draft Apr 28, 2026 ·Llama-3.3-70B-Instruct, Qwen3-0.6B, Qwen3-4B, Qwen3-14B
Three sequential benign LoRA fine-tunes erode Llama-2-7B-Chat composite safety from 91.4 to 43.6 across all 6 domain orderings, while Fisher-eigendecomposition isolates safety in a sharply-decaying ~8-direction LoRA-parameter subspace
draft Apr 20, 2026 ·Llama-2-7B-Chat, Mistral-7B-Instruct
Attention streams sustain quasi-psychological continuity across token-time; persona regions in low-dimensional persona space motivate two new candidates for LLM individuation, supplementing the virtual instance view
draft Apr 18, 2026 ·Qwen 3 32B
Discourse-level narrative features alone separate AI-generated from human-authored fiction at 93.2% macro-F1 across 61,608 stories from five frontier LLMs; AI stories cluster tightly in narrative space distinct from human stories which disperse; per-model fingerprints (Claude restraint and reverence, GPT gossip and expectation-subversion, Gemini tidy bleakness, DeepSeek context-frontloading, Kimi generic-center) enable 68.4% F1 six-way attribution
draft Apr 3, 2026 ·Claude Sonnet 4.6, GPT 5.4, Gemini 3 Flash, DeepSeek V3.2, Kimi K2.5
Counterfactual chain-of-thought scaffold drives an unsupervised sycophancy metric (SWAY) to near zero across six models on three datasets, while a direct 'do not be sycophantic' instruction amplifies sycophancy in some models and over-corrects in others

draft Mar 16, 2026 ·o3, OpenAI o-series models (newer training checkpoints)
Three input-framing features (non-question form, epistemic certainty, I-perspective) causally drive sycophancy across GPT-4o, GPT-5, and Sonnet-4.5; rewriting the input as a question outperforms 'don't be sycophantic' instructions as a mitigation
draft Feb 27, 2026 ·GPT-4o, GPT-5, Claude Sonnet 4.5
GPT-4.1 self-assessments of harmfulness track an inverted-V trajectory across base / misaligned / realigned fine-tunes for both trivia and code domains; Spearman ρ between self-assessment and independently measured harmfulness is 0.79 across 15 model variants
draft Feb 16, 2026 ·GPT-4.1, GPT-4.1 mini, GPT-4.1 nano
General misalignment is more efficient, more stable, and more influential on pre-training data than narrow misalignment — explaining why EM is the default fine-tuning solution

draft Jan 30, 2026 ·Llama-3.1-8B-Instruct, Qwen2.5-14B-Instruct
Bias-variance decomposition of frontier-model errors: longer reasoning increases error incoherence (variance fraction); scale does not consistently reduce it; future failures may look more like industrial accidents than coherent pursuit of misaligned goals
