I see no posts about OpenAI Codex. I was under the impression that it also is a very popular tool and virtually as powerful as Claude Code.
Where am I wrong? Is Codex not popular? Is it significantly worse than Claude Code? Is it being "cancelled" because of OpenAI cooperating with the US Department of War?
I regularly use both Claude Code and Codex; work pays for Claude, my personal sub is for Codex.
Opus 4.7 and GPT 5.5 seem equally competent. They have distinct “feels” when interacting, and perhaps each have strengths and weaknesses, but I don’t really see one as better than the other.
I don't use the harness anymore, but it was fine. I switched to an agnostic harness that uses a multitude of models -- often the GPT ones.
Anyone that cares about quality first and foremost switches harnesses pretty fast, the features are just insane. I want to be able to dictate the models that do vision versus code, for example. I want agentic memory that I can manage. I want better permissions controls than CC or codex, I want better file editing and reversion; better harnesses out there for all of these points.
