Recently, OpenAI is preparing a preview version of its next-generation language model, GPT-4.5, sparking widespread interest. This development was reportedly discovered within the ChatGPT Android application as an announced experimental option, though currently inaccessible. According to recent notifications, GPT-4.5 will initially be exclusively available to Pro subscribers.
GPT-4.5 is expected to succeed GPT-4 in the free version of ChatGPT, potentially offering higher conversation limits. Plus and Pro users will have early access to this new version. However, the specific features and availability of GPT-4.5 remain unclear at present; clicking on related notifications yields no response.
OpenAI's recent notification invited Pro users to test this latest model. It's worth noting that the Pro subscription costs $200 per month, offering more features and fewer limitations compared to the $20 Plus subscription and the free plan.
