🔒 SECURITY
🎯 AI-Assisted Security Audits • Backdoor Detection Challenges • Reverse Engineering Accessibility
💬 "The whole field of working with binaries becomes accessible to a much wider range of software engineers."
• "Measuring false positives when you ask the model to complete a detection related task may be a good way of doing that."
🛠️ TOOLS
🎯 AI-assisted software development • Planning and documentation • Constraining AI model outputs
💬 "I try these staging-document patterns, but suspect they have 2 fundamental flaws"
• "For me, I treat the LLM as model training + post processing + input tokens = output tokens"

"nanollama — train Llama 3 from scratch.
I've been working on a framework for training Llama 3 architecture models from scratch: not fine-tuning, not LoRA, actual from-zero pretraining. The output is a llama.cpp-compatible GGUF file.
The whole pipeline is one command:

🎯 Easy data setup • Hardware performance • Local LLM development
💬 "You should prepare for people example datasets"
• "this is localllama so i gotta ask"
🛠️ TOOLS
"Most discussions about RAG and LLM agents focus on “what architecture to use” or “which model / vector store is better”. In practice, the systems I have seen fail in the same, very repetitive ways across projects, companies, and even different tech stacks.
Over the past years I have been debugging ..."
🛠️ TOOLS
"I got Llama 3.2 1B running inference entirely on the AMD NPU on Linux. Every operation (attention, GEMM, RoPE, RMSNorm, SiLU, KV cache) runs on the NPU; no CPU or GPU fallback. As far as I can tell, this is the first time anyone has publicly documented this working on Linux.

"Some transformer attention heads appear to function as membership testers, dedicating themselves to answering the question "has this token appeared before in the context?" We identify these heads across four language models (GPT-2 small, medium, and large; Pythia-160M) and show that they form a spec..."

"Large language models (LLMs), and conversational agents based on them, are exposed to personal data (PD) during pre-training and during user interactions. Prior work shows that PD can resurface, yet users lack insight into how strongly models associate specific information to their identity. We audi..."

"Reasoning with LLMs increasingly unfolds inside a broader verification loop. Internally, systems use cheap checks, such as self-consistency or proxy rewards, which we call weak verification. Externally, users inspect outputs and steer the model through feedback until results are trustworthy, which w..."

"Instruction-following language models are trained to be helpful and safe, yet their safety behavior can deteriorate under benign fine-tuning and worsen under adversarial updates. Existing defenses often offer limited protection or force a trade-off between safety and utility. We introduce a training..."

"This paper introduces KLong, an open-source LLM agent trained to solve extremely long-horizon tasks. The principle is to first cold-start the model via trajectory-splitting SFT, then scale it via progressive RL training. Specifically, we first activate basic agentic abilities of a base model with a..."

"In multi-agent IR pipelines for tasks such as search and ranking, LLM-based agents exchange intermediate reasoning in terms of Chain-of-Thought (CoT) with each other. Current CoT evaluation narrowly focuses on target task accuracy. However, this metric fails to assess the quality or utility of the r..."
