Things I’m noticing, thinking, and building, mostly about AI.

GPT-5.5

I like Codex and the desktop App a lot, but there is something off with 5.5. It doesn’t seem to put in the effort to do what I ask for (lazy?), it talks to me like an alien when I refer to something from just two messages ago, and it is just not good with long context.

Maybe I am used to the incredible long context conversations with 5.4, maybe the lesser context is really hurting, maybe it is not for every problem, maybe I need to update my workflow, but I am yet to experience what the hype about 5.5 is.

Either way, 5.5 is not just an incremental model. There is a lot going on with this model, and you cannot just switch from 5.4 to 5.5 and assume everything will be okay.
