My model + harness stack these days: 1. Kimi K3 is the best OSS coding model. GLM-5.3 is next. 2. DeepSeek V4.1 Flash is my pick for easy/moderate tasks: insanely fast and cheap. 3. I reach for Astra for complex tasks. 4. Codex works better with OSS models. Claude Code can make the same model cost 2x more.
