| | Making sense of… | | “MONOCULTURE” IN MULTIAGENT SYSTEMS: WHEN AIs OVERSEE OTHER AIs | | What seems like good practice in multi-agent systems has a hidden flaw. When multiple AI agents review the same task and corroborate the same facts, it feels like reliability. But if those agents were built on the same foundation model, or trained on similar data, they share the same blind spots. A flaw present in every agent isn’t caught by adding more agents, and it becomes a structural property of the system. Researchers call this “monoculture collapse.” True redundancy requires true diversity. And it’s hard to implement well. | | Read the full analysis → | |

| | On the radar | | 1. The UK AISI evaluates GPT-5.5 and Claude Mythos cyber capabilities. This is a major government assessment of next-generation models, and suggests cyber risks are accelerating faster than governance frameworks can adapt. In a recent media release, ASIC urges all licensees and market participants to strengthen their cyber resilience measures. | | 2. APRA signals more prescriptive AI oversight for the financial sector. Australia’s financial regulator’s industry letter hints at mandatory AI governance standards (potentially a template for other sectors). | | Trendline. “Trust” is a word we’ve explored in much of our work at Gradient, including in techniques for human oversight of AI systems and in the interaction between AI agents. It is a crucially important one for confident adoption of AI in Australia, but how well it is used in the context of AI and what type of trust the discourse alludes to is unclear. Trust in AI is a complex, shifting concept, dependent on the specific system, individuals, and context, and this is explored thoroughly in Principles for understanding trust in AI. Consequently, comprehending AI trust requires examining both human perception and the desired societal outcomes. |

| | Question of the month | | In recent conversations with a large company in financial services, we encountered a question we really want to learn your take on: How should large organisations govern agentic AI systems when multiple models, vendors, and business units are involved? Traditional governance frameworks assume single-model deployments with clear accountability lines. But when AI agents interact across organisational boundaries, think procurement talking to finance, customer service routing to legal, who’s responsible when things go wrong? How much human oversight is practically feasible? Let us know! We read every answer, and they inform our research. | | Reply to share your answer → | |
