Actionable Activation Directions for Detecting and Mitigating Emergent Misalignment Across Language Model Families

via Arxiv 👤 Abdul Rafay Syed 📅 2026-06-18

⚡ Score: 8.1

"Fine-tuning language models on insecure code induces emergent misalignment with poorly understood internal structure. We investigate whether this misalignment corresponds to a causally actionable activation-space direction shared across architectures. Across four instruction-tuned model families (Qw..."

Execution-State Capsules: Graph-Bound Execution-State Checkpoint and Restore for Low-Latency, Small-Batch, On-Device Physical-AI Serving

via Arxiv 👤 Liang Su 📅 2026-06-18

⚡ Score: 7.2

"Mainstream LLM serving systems reuse prefix work mainly through paged or radix key-value (KV) caches. This is highly effective for high-throughput, high-concurrency serving, but it manages only one positional fragment of execution state: the KV cache. We study the opposite regime: low-latency, small..."

How Transparent is DiffusionGemma?

via Arxiv 👤 Joshua Engels, Callum McDougall, Bilal Chughtai et al. 📅 2026-06-18

⚡ Score: 7.0

"LLM reasoning transparency is a critical affordance for understanding model decisions, mitigating misuse and misalignment, and debugging surprising model behaviors. However, DiffusionGemma performs a larger fraction of its computation in a continuous latent space; does this make its reasoning less t..."

What Do Safety-Aligned LLMs Learn From Mixed Compliance Demonstrations?

via Arxiv 👤 Sihui Dai, Mann Patel 📅 2026-06-18

⚡ Score: 6.9

"Prior work has shown that in-context demonstrations can jailbreak language models, but it remains unclear how models interpret different types of compliance demonstrations. We study this by mixing benign compliance demonstrations (non-harmful request, helpful response) with harmful compliance demons..."

⚡ Score: 6.9

"Real-world computer-use tasks often span multiple applications and devices, requiring agents to coordinate heterogeneous environments under dynamic runtime failures. Existing multi-device agent systems support task decomposition and cross-device assignment, but recovery remains largely coarse-graine..."
