OpenAI launches GPT-4.5 as its largest AI model
OpenAI has launched GPT-4.5, code-named Orion, its largest AI model yet, trained with more computing power and data than previous versions. Available to ChatGPT Pro subscribers and developers on paid API tiers, GPT-4.5 enhances pattern recognition and user intent understanding while aiming to reduce hallucinations. It uses unsupervised learning techniques and includes improved safety measures, but currently lacks multimodal capabilities.
