I switched to Codex in November 2025 because I couldn't stand the smarmy, "You're absolutely right" anymore. Codex at the time offered less sycophancy and more pushback when I was actually wrong. I also feel it writes cleaner code since it follows my instructions better to not write unrequested code, not create unnecessary abstractions, and not reinvent any wheels. I use LLMs on a tight-leash in HITL for web development, monitoring traces as it goes. I rarely use it for more than just writing code that I specify and I rarely let it "have it's head" and work unmonitored. I use it on the API plan since I need it to be reliable. No outage issues that I can recall.
