agent-based modelling

United Nations University researchers have published a technical and governance framework for using large language models in agent-based modelling, titled 'From Plausible Agents to Accountable Simulation'. The work addresses how LLM-enabled simulations, which can produce realistic-seeming artificial agents, can be made verifiable, transparent and accountable when used for research and policy analysis. It proposes standards for evaluating whether simulated agent behaviour is plausible and for governing the use of such models.

OpenAI's DevDay 2026 put the spotlight on lower-cost models and always-on agents rather than unveiling a new flagship model, according to DigiTimes. The shift suggests the company is prioritizing affordability and continuous, agent-based functionality in ChatGPT over headline-grabbing model releases. Observers see it as a sign of a maturing strategy focused on practical deployment and pricing.
