In the world of chemical engineering, optimization is both a science and an art. But when operating conditions are ambiguous or constraints are missing, even the most robust solvers stumble. Enter the next-gen solution: a team of LLM agents that not only understand the problem but define it. When Optimization Meets Ambiguity Traditional solvers like IPOPT or grid search work well—if you already know the boundaries. In real-world industrial setups, however, engineers often have to guess the feasible ranges based on heuristics and fragmented documentation. This paper from Carnegie Mellon University breaks the mold by deploying AutoGen-based multi-agent LLMs that generate constraints, propose solutions, validate them, and run simulations—all with minimal human input. ...

Human-AI collaboration is easy to romanticize in theory but hard to operationalize in practice. While reinforcement learning agents have dazzled us in games like Go and StarCraft, they often stumble when asked to cooperate with humans under real-world constraints: imperfect information, ambiguous signals, and no chance to train together beforehand. That’s the realm of ad-hoc teamwork—and the latest paper from Oxford’s FLAIR lab introduces a critical step forward. The Ad-Hoc Human-AI Coordination Challenge (AH2AC2) tackles this problem by leveraging Hanabi, a cooperative card game infamous among AI researchers for its subtle, communication-constrained dynamics. Unlike chess, Hanabi demands theory of mind—inferring what your teammate knows and intends based on sparse, indirect cues. It’s a Turing Test of collaboration. ...

As large language models (LLMs) evolve from mere tools into interactive agents, they are increasingly expected to operate in multi-agent environments—collaborating, competing, and communicating not just with humans but with each other. But can they understand the beliefs, intentions, and misunderstandings of others? Welcome to the world of Theory of Mind (ToM)—and the cleverest AI benchmark you haven’t heard of: Decrypto. Cracking the Code: What is Decrypto? Inspired by the award-winning board game of the same name, Decrypto is a three-player game of secret codes and subtle hints, reimagined as a benchmark to test LLMs’ ability to coordinate and deceive. Each game features: ...

When deploying large language models (LLMs) on mobile devices, edge servers, or any resource-constrained environment, quantization is the go-to trick. It slashes memory and compute costs by reducing model precision from 16-bit or 32-bit floating points to 8-bit or even 4-bit integers. But there’s a problem: this efficiency comes at a cost. Quantization can quietly erode the safety guarantees of well-aligned models, making them vulnerable to adversarial prompts and jailbreak attacks. ...

In the world of large language models (LLMs), answers often emerge from an intricate internal dialogue. But what if we could locate the few sentences within that stream of thoughts that disproportionately steer the outcome—like anchors stabilizing a drifting ship? That’s exactly what Paul Bogdan, Uzay Macar, Neel Nanda, and Arthur Conmy aim to do in their new work, “Thought Anchors: Which LLM Reasoning Steps Matter?”. This study presents an ambitious trifecta of methods to trace the true influencers of LLM reasoning. ...

When it comes to language model agents, more minds may not always mean merrier results. Multi-agent reinforcement learning (MARL) promises a flexible path for decomposing and solving complex tasks, but coordinating multiple large language models (LLMs) remains riddled with instability, inefficiency, and memory fragmentation. Enter JoyAgents-R1, a novel framework that proposes an elegant, scalable solution for jointly evolving heterogeneous LLM agents using Group Relative Policy Optimization (GRPO). Developed by researchers at JD.com, JoyAgents-R1 combines memory evolution, policy optimization, and clever sampling strategies to form a resilient multi-agent architecture capable of matching the performance of larger SOTA models with far fewer parameters. ...

When it comes to deploying large language models (LLMs) efficiently, few challenges are as stubborn—and misunderstood—as activation outliers. For years, engineers have treated them like a natural disaster: unpredictable but inevitable. But what if they’re more like bad habits—learned and fixable? That’s the provocative premise behind a new framework called Outlier-Safe Pre-Training (OSP). Developed by researchers at Korea University and AIGEN Sciences, OSP proposes a simple but radical shift: instead of patching over outliers post hoc with quantization tricks, why not train the model to never form outliers in the first place? ...

Divide and Conquer: How LLMs Learn to Teach Designing effective lessons for training online tutors is no small feat. It demands pedagogical nuance, clarity, scenario realism, and learner empathy. A recent paper by Lin et al., presented at ECTEL 2025, offers a compelling answer to this challenge: use LLMs, but don’t ask too much at once. Their research reveals that breaking the task of lesson generation into smaller, well-defined parts significantly improves quality, suggesting a new collaborative model for scalable education design. ...

When the DAO hack siphoned millions from Ethereum in 2016, the blockchain world learned a hard lesson: code is law, and bad law can be catastrophic. Fast forward to today, and smart contract security still walks a tightrope between complexity and automation. Enter Smart-LLaMA-DPO, a reinforced large language model designed not just to find vulnerabilities in smart contracts—but to explain them, clearly and reliably. 🧠 Beyond Detection: Why Explanations Matter Most smart contract vulnerability detectors work like smoke alarms—loud when something’s wrong, but not exactly helpful in telling you why. The core innovation of Smart-LLaMA-DPO is that it speaks the language of developers. It explains vulnerabilities with clarity and technical nuance, whether it’s a reentrancy flaw or an oracle manipulation scheme. And that clarity doesn’t come from magic—it comes from Direct Preference Optimization (DPO), a training method where the model learns not just from correct labels, but from expert-ranked explanations. ...

In the symphony of innovation, TRIZ has long served as the structured score guiding engineers toward inventive breakthroughs. But what happens when you give the orchestra to a team of AI agents? Enter TRIZ Agents, a bold exploration of how large language model (LLM) agents—armed with tools, prompts, and persona-based roles—can orchestrate a complete innovation cycle using the TRIZ methodology. Cracking the Code of Creativity TRIZ (Theory of Inventive Problem Solving), derived from the study of thousands of patents, offers a time-tested approach to resolving contradictions in engineering design. It formalizes the innovation process through tools like the 40 Inventive Principles and the Contradiction Matrix. However, its structured elegance demands deep domain expertise—something often scarce outside elite R&D centers. ...
