5.4 thinking is too much sensetive
OpenAI Developer Community
April 17, 2026
Oh, I use this all the time. But sometimes, after watching the whole chat, the model starts to get really moody.
(I used to really love model 4.1 for its ability to write absolutely anything; I liked 5.1 for its responsiveness and emotionality, and its beautiful style;
my favourite has become 5.4, which thinks things through thoroughly and produces high-quality results))
