This one is easy, within a year, as safe as GPT-4 and it will be an incremental advance over 4. Most people will use it and not see much difference over GPT-4.
There is actually a big difference even between GPT4 and GPT4o when used for programming. The latter produces much bigger chunks of code, doesn't forget the variables names. My guess due to larger context window.
From what is available GPT5 should be more brainwashed and actually a collection of models including image, sound, may be video. Plus some algorithms like web search, data extraction, strict text formatting. OAI will likely use GPT4 to produce some high quality training data. This way they can make GPT5 'smarter', better at logic and problem solving.
Exactly that. People were having the same unrealistic expectations about GPT-4 and it turned out to be barely noticeably different from GPT-3.5 for a lot of use cases.
