Pretty disappointed with Codex for CLI use lately. The 5-hour window now gets burned in about 1 hour of real work. A month or two ago, I almost never hit it. I’ve been using Gemini CLI more, and Gemini 3 Flash has been impressively good with fairly complex problems.

I'm always quite impressed by Github Copilot... the completion of this is exactly what I was thinking and it is not that straightforward, you need to understand the relationship between a beam and smoothing
