Reva: Real-Time Vulnerability Detection through Contextual Probing of Large Language Models

As coding agents ship code faster than security teams can review it, you need vulnerability detection that runs at agent speed, not human speed. REVA cracks this by capturing what makes agent reasoning reliable (context gathering, evidence weighing) and baking it into a fast detector. If you're deploying agent-generated code in production, this is the kind of system that sits between agent output and merge.

Learn the Interface, Not the Implementation: Output Representation Dominates Training Regime in LLM-Based RTL Generation

This has real implications for anyone building LLM-based hardware design tools. The finding is stark: format matters more than how you train the model. Stop optimizing fine-tuning strategies and start thinking about the interface between the LLM and the formal verifier. This is actionable guidance.

Discovering state-of-the-art quantum circuits with large language models

This is a concrete win: LLMs as circuit designers, not as general problem-solvers. The framework is simple, the results are measurable, and the tasks span real domains from chemistry to optimization. For builders exploring LLM-guided synthesis in other hardware domains, this is a template worth studying.

PreciseCoder: Faithful and Generalizable Debugging Beyond Unit-Test Rewards

Unit-test-only rewards teach models to edit promiscuously and hallucinate bugs in correct code. This is the first credible fix: adding a signal for precise, verified edits. The numbers are concrete (3 vs 7-15 lines per fix) and the generalization from toy problems to repo-level repair is exactly what matters for real codebases. If you're building code-fixing infrastructure, this changes your training recipe.
