GPT-4.5 is a large language model developed by OpenAI that represents an intermediate capability level between GPT-4 and future flagship models. For enterprise AI governance, GPT-4.5 is relevant because organizations must evaluate its performance characteristics, safety properties, and compliance implications when considering deployment in production systems. Understanding this model's capabilities and limitations helps enterprises make informed decisions about model selection, risk assessment, and regulatory alignment for their AI initiatives.

GPT-4.5 Arrives as 'Research Preview,' Triggering Procurement and Risk Controls Before Any Production Use

OpenAI released GPT-4.5 under a research preview designation, describing it as its largest and most capable chat model to date, in notes published to the OpenAI Help Center. The research preview status signals that the model has not yet reached a full general availability release, which carries direct implications for how enterprises may procure, test, and deploy it. Organizations that treat preview models as production-ready without appropriate governance controls risk accepting undefined risk profiles that fall outside standard AI risk management processes.
