My wife has a Gemini AI pro Ultra whatever that she paid for to help with her academic research, but uses barely. She was generous to login with it on my computer to let me use the cli with her credentials. So Gemini-3.0-pro comes from there. I use OpenAI and Claude API keys with EUR 20 credits that I topped up (pay per use). I've mostly settled on Gemini-3.0, but occasionally pit codex, Gemini and Claude at each other at a gnarly problem reviewing each other's work, and proposing actionable changes with clear reasoning. They tend to catch teachers blind spots, an dI get to learn something from their reviews as well.
