Almost all my tooling is years (or decades) old and stable. But the code assistant LLM scene effectively didn't exist in any meaningful way until this year, and it changes almost daily. There is no stability in the tooling, and you're missing out if you don't switch to newer models at least every few weeks right now. Codex (OpenAI/ChatGPT CLI) didn't even exist a month ago, and it's a contender for the best option. Claude Code has only been out for a few months. I use Neovim in tmux in a terminal and haven't changed my primary dev environment or tooling in any meaningful way since switching from Vim to Neovim years ago. I'm still changing code AIs as soon as the next big thing comes out, because you're crippling yourself if you don't.
