I Let a Small Model Train on Its Own Mistakes. It Reached 80% on HumanEval and Beat GPT-3.5 on Math

"A few months ago, I got stuck on one line in the DeepSeek-R1 paper. It said models could improve through verifiable rewards. That sounded almost magical to me. Not because it was impossible, but because it made me wonder something very simple: What if a model could teach itself to code, without hu..."

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..."

Evaluated a RAG chatbot and the most expensive model was the worst performer. Notes on what actually moved the needle.

"We had a customer support RAG bot. Standard setup: ChromaDB, system prompt, an LLM doing generation. Nobody had actually measured the response quality. In the name of evaluation, I only had a keyword matching script producing numbers that looked like scores and meant nothing. I went in to fix this..."

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

Where Does Reasoning Break? Step-Level Hallucination Detection via Hidden-State Transport Geometry

"Large language models hallucinate during multi-step reasoning, but most existing detectors operate at the trace level: they assign one confidence score to a full output, fail to localize the first error, and often require multiple sampled completions. We frame hallucination instead as a property of..."

Negation Neglect: When models fail to learn negations in training

"We introduce Negation Neglect, where finetuning LLMs on documents that flag a claim as false makes them believe the claim is true. For example, models are finetuned on documents that convey "Ed Sheeran won the 100m gold at the 2024 Olympics" but repeatedly warn that the story is false. The resulting..."

History Anchors: How Prior Behavior Steers LLM Decisions Toward Unsafe Actions

"Frontier LLMs are increasingly deployed as agents that pick the next action after a long log of prior tool calls produced by the same or a different model. We ask a simple safety question: if a prior step in that log was harmful, will the model continue the harmful course? We build HistoryAnchor-100..."

The Trust–Oversight Paradox: As AI Gets Better, Humans May Stop Really Overseeing It

Widening the Gap: Exploiting LLM Quantization via Outlier Injection

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