OpenAI has officially unveiled GPT-4.5, its largest and most advanced AI model yet, code-named "Orion." Trained with unprecedented computing power and data, GPT-4.5 promises enhanced capabilities. However, OpenAI clarifies it doesn’t classify the model as a "frontier" breakthrough.  

Starting today, developers on paid API tiers can access GPT-4.5, while ChatGPT Pro subscribers ($200/month) will get a research preview in ChatGPT from Thursday. This release marks another step in OpenAI’s mission to push AI boundaries, though the company remains cautious about overhyping its advancements.  

Thoughts? GPT-4.5 is a significant upgrade, but OpenAI’s tempered language suggests even bigger innovations may be on the horizon.
