looks like openai is prepping gpt-5 based on new web app strings! also seeing mentions of gpt-5-pro and a few gpt-4o variants like gpt-4o-mini-filled.
new chatgpt web bundle just dropped and it's spicy. seeing "gpt-5", "gpt-5-thinking", and even "gpt-5.6-luna-wm" alongside a bunch of new gpt-4o model names. very interesting.
