You say Claude, I too would prefer not to read reams of comments or an essay everytime I revise the plan in plan mode, but do you know if any other tools are better than it? I've never used Codex, but I remember Claude Web's natural conversational approach being a welcome sight compared to ChatGPT's overly-formatted listicles.
My experience is Codex is much better but less creative. I use its agent through GitHub Copilot or the agent interface from JetBrains. Try the GPT Sol 5.6 on medium, it gives me good results
I switched to codex just before the Fable release. I got sick of Claude being lazy and not completing tasks. Imo, codex is currently a much better model, and it also seems to be technically stronger on the type of applied math and theory heavy programming I like to do.
