I've been using OpenCode Zen with Opus 4.5 the last few days at @nprofile1q...'s insistence, but I've found that it's way more "hot" than Claude. I have to keep a very tight leash to keep it from going off the rails with ill-considered refactors. The way that Claude Code eliminated this behavior is why I finally started having success with vibe coding. Anyone know how to turn the temperature down a little?
