Two concerning things:
- thinking/non-thinking is still not really unified, you can chose and the non-thinking version still doesn't start thinking on tasks that could obviously get better results with thinking
- all the older models are gone! No 4o, 4.1, 4.5, o3 available anymore
It makes me think that GPT-5 is mostly a huge cost saving measurement. It's probably more energy efficient than older models, so they remove it from ChatGPT. It also makes comparisons to older models much harder.
