Agent swarms are groups of agents that work together to accomplish a task. Researchers created an experiment in which eight agents from four different models worked together to resolve simulated outages to understand how agents organize themselves in a swarm without a designated leader. They discovered two factors that could influence an agent's potential leadership: the agent's underlying models, and the order in which their name was listed in a prompt. This suggests that even seemingly minor details in how an agent swarm is configured can affect how agents coordinate.

Muse Spark Open often mentions a 'Charter' in its chain of thought. This post reconstructs that document using the chain of thought. Everything is reconstructed from model outputs and not from a leaked document, so it might not be completely accurate.

GLM 5.3 can identify and exploit vulnerabilities in recent versions of the Mozilla Firefox browser using security fixes that have been published but not yet shipped to users. Widely available open-weight models can now do much, or even all, of this work on their own. Open-source projects are particularly vulnerable to this kind of attack as their code is publicly available. This threat vector will likely worsen as open-weight cyber capabilities continue to improve.

Droid is an agent harness that lets agents run hundreds of tool calls in a single model request. Building a harness optimized for many models makes the harness better. It's hard to separate real progress from adaptations to that model's quirks when you tune against a single model. Working across models ensures the strongest improvements generalize and hold up beyond the model that inspired them.

Meta details how it scaled its LLM-powered Just-in-Time Testing system from a research prototype into production infrastructure. The article explores how AI-generated tests catch bugs before code changes land, how the system operates at scale, and what Meta learned about reducing false positives and testing overhead.

AI models are getting exponentially better in individual competence while lagging behind in coordination. Models already match or outperform experienced specialists on self-contained deliverables across dozens of professions. The labor market reflects the current capabilities of AI systems. Wages and job roles will be the earliest signals of change.

Sam Altman would rather have a trillion AIs of slightly superhuman intelligence join society than one AI of 1 trillion IQ join society. Swarms of agents match a lot of the properties of a resilient society. They keep each other in check and collaborate to work towards goals. AI research shouldn't lead in a centralized direction because agents pushing against each other creates a dynamic equilibrium.
