Oxford paper finds frontier LLM agents fail cross-vendor coordination
The practical implication is that agent interoperability breaks down not from capability gaps but from unstated conventions, so inter-agent protocols may need explicit shared norms rather than smarter models. Teams building multi-agent systems that span different vendors should add instructions telling agents to avoid unstated conventions and prefer actions any partner can read correctly. The finding applies to anyone chaining GPT-5.2 and Gemini 3 Pro agents together today.
