85 GPU-hours comparing 5 abliteration methods on Qwen3.6-27B: benchmarks, safety, weight forensics - Abliterlitics

"I've been building Abliterlitics, an open-source abliteration forensics toolkit. The idea is straightforward: take the same base model, compare the different abliteration techniques others have applied, then measure what actually changed using benchmarks..."

MetaBackdoor: Exploiting Positional Encoding as a Backdoor Attack Surface in LLMs

"Backdoor attacks pose a serious security threat to large language models (LLMs), which are increasingly deployed as general-purpose assistants in safety- and privacy-critical applications. Existing LLM backdoors rely primarily on content-based triggers, requiring explicit modification of the input t..."

Your AI agent is one poisoned webpage away from doing something catastrophic

"If your agent browses the web, reads emails, or pulls from a database β€” any of that content can contain hidden instructions that hijack it. This isn’t theoretical. It’s happening in production right now. A webpage footer tells your agent to forward credentials. An email signature tells it to ignore..."

Talk is (Not) Cheap: A Taxonomy and Benchmark Coverage Audit for LLM Attacks

"We introduce a reusable framework for auditing whether LLM attack benchmarks collectively cover the threat surface: a 4$\times$6 Target $\times$ Technique matrix grounded in STRIDE, constructed from a 507-leaf taxonomy -- 401 data-populated and 106 threat-model-derived leaves -- of inference-time at..."

Position: Behavioural Assurance Cannot Verify the Safety Claims Governance Now Demands

"This position paper argues that behavioural assurance, even when carefully designed, is being asked to carry safety claims it cannot verify. AI governance frameworks enacted between 2019 and early 2026 require reviewable evidence of properties such as the absence of hidden objectives, resistance to..."

Forgetting That Sticks: Quantization-Permanent Unlearning via Circuit Attribution

"Standard unlearning evaluations measure behavioral suppression in full precision, immediately after training, despite every deployed language model being quantized first. Recent work has shown that 4-bit post-training quantization can reverse machine unlearning; we show this is not a tuning artefact..."

OpenDeepThink: Parallel Reasoning via Bradley--Terry Aggregation

Scaling breadth by sampling multiple candidates in parallel is straightforward, but introduces a selection bottleneck: choosing the best candidate wi..."

Self-Distilled Agentic Reinforcement Learning

On-Policy Self-Distillation (OPSD) complements RL by introducing dense token-level guidance from a teacher..."

From Text to Voice: A Reproducible and Verifiable Framework for Evaluating Tool Calling LLM Agents

We study whether verified text benchmarks can be converted into controlled audio-based tool calling evaluations without re-annotating the tool schema and gold labels. Our dat..."

MemEye: A Visual-Centric Evaluation Framework for Multimodal Agent Memory

Widening the Gap: Exploiting LLM Quantization via Outlier Injection

"LLM quantization has become essential for memory-efficient deployment. Recent work has shown that quantization schemes can pose critical security risks: an adversary may release a model that appears benign in full precision but exhibits malicious behavior once quantized by users. However, existing q..."

ML-Embed: Inclusive and Efficient Embeddings for a Multilingual World

Concurrency without Model Changes: Future-based Asynchronous Function Calling for LLMs

"Function calling, also known as tool use, is a core capability of modern LLM agents but is typically constrained by synchronous execution semantics. Under these semantics, LLM decoding is blocked until each function call completes, resulting in increasing end-to-end latency. In this work, we introdu..."

Training ML Models with Predictable Failures

"Estimating how often an ML model will fail at deployment scale is central to pre-deployment safety assessment, but a feasible evaluation set is rarely large enough to observe the failures that matter. Jones et al. (2025) address this by extrapolating from the largest k failure scores in an evaluatio..."

Improving Multi-turn Dialogue Consistency with Self-Recall Thinking

Ran the same models across Strix Halo, RTX 3090, and RTX 5070 because I wanted my own numbers
