GPT-4.5 is getting closer to release, OpenAI Android client has released relevant information, Pro users can prepare, Plus users please wait

OpenAI Android client leaked the release signal of GPT-4.5, and Pro users will be the first to experience it.
Core content:
1. GPT-4.5 related descriptions were found in the OpenAI Android client code
2. Pro users will get access to the latest large models, and Plus users need to wait
3. GPT-4.5 may be a research preview version, and performance and speed have attracted attention
Recently, a screenshot circulated on the Internet, showing that the description of GPT-4.5 appeared in the application string file (strings.xml) of the OpenAI Android client. This discovery has attracted widespread attention, suggesting that OpenAI may be about to launch its latest large-scale language model - GPT-4.5. The information was first discovered and shared by a developer Twitter user, and the screenshot content seems to come from the application resource file of the ChatGPT Android client.
Earlier, a GPT-4.5 trial prompt appeared in the upper right corner of OpenAI's Android client, as shown below.
After grabbing the client information, several strings related to model selection and prompts were found, the most eye-catching of which are the following two lines:
Among them, “Pro users now have access to our newest, largest model” means that Pro users will be able to use OpenAI’s latest and largest model, and “Try the GPT-4.5 research preview” directly points out the name of GPT-4.5 and indicates that this may be a research preview version (Research Preview).
However, does “largest” mean larger than the rumored 1.8 trillion parameters of GPT-4? In that case, the generation speed is worrying.
In addition, Pro users can use it, but what about Plus paying users? $20 is not a big deal!
