Yesterday OpenAI announced GPT-5. Altman has claimed that it has reached PhD level reasoning. It turned up in my account this morning, so I thought I’d have a go. Interested as I am in Project 2025 I asked it a general question: A disappointing response. I doubt it’s censoring results; rather my guess is that it’s saving money by not doing any kind of search. For comparison, here is the response from a few months ago under version 4:

I hold positions in several solar power generation companies and funds in the UK. How do they make money? Clearly they sell electricity! But it turns out it’s more complicated than that. There isn’t a simple flat rate per kWh (even though that’s what I get for the electrity I sell back to the grid from my solar PV installation). Instead electricity is priced by the system of marginal pricing.

A couple of weeks ago we headed off to Makrigialos on the south eastern coast of Crete. This is an excellent, relatively undeveloped resort, with plenty of amenities. I won’t go into detail except to mention the superb Splash Bar! Here however I want to mentions some walks we undertook over the course of those two weeks. From Makrigialos there are several within easy reach, either right on the doorstop or a short (< 1 hour) drive.
