Claude's 4.6 - 4.7 transition made me discover codex, and with gpt 5.5 there is no way i'm going back

Codex has been incredibly slow for the past few days. I think OpenAI is running out of compute in the face of increasing demand.

My experience has been that 5.4 is slower than 5.5 (confound: I use >512k max context size for 5.4, though it seems slower even below the normal size)
