**2025-08-08** Just after the summer break, I updated to GPT-5, no longer needing to choose a Reasoning model such as 4o, or even 4. I am living with a person who answers to various issues with the knowledge of a graduate student. Having a graduate student friend by my side at all times as a partner in my current daily research expands my knowledge base, my interests, and my enjoyment. Even the scope of activities and experiences can be boosted a lot. Of course, I can't always believe everything your acquaintances say, and our decisions and actions are our own responsibility, but it is easy to imagine having a nice housemate in the house. Of course, the same goes for the really important stories, which are not so easily found in people. **2025-04-07** Monday, introduced on April 1st, has been drawing attention. Its languid, sarcastic tone contrasts with the usual voice experience that cheerfully offers support with a “yes, of course.” In a way, this different tone carries a certain quality that might even feel more trustworthy. It’s said to be the 10th voice added to Advanced Voice Mode. **2025-04-01** Image generation is evolving. My daughter was working on a prep school assignment about creating color compositions based on sound. She wrote a draft featuring a rapper performing. We used that draft to experiment—changing the angle of view, adjusting the color tones. It’s amazing that we can study things like this now. ![[Pasted image 20250402012454.png |450]] ![[Pasted image 20250402012553.png |450]] ![[Pasted image 20250402012623.png |450]] What left a strong impression on me was not only the quality of the message in the images, but also how well they were directed with appropriate patterns. MUJI’s “80-point design” products didn’t make you think “this is great,” but rather “this is good enough” — and that felt just right. Nowadays, that sensibility has even extended to DAISO’s _Standard Products_. When that happens, relying solely on plain, unfiltered expressions — like a simple bowl of udon with no cultural or experiential seasoning — eventually becomes tiresome. **2023-02-22** I became a Pro user. **2022-12-05** I looked up when I first started using ChatGPT, and it was December 5, 2022. OpenAI launched it on November 30, 2022.
