Using Codex GPT 5.5. in VS Code every day now writing pretty complex C++ -- excellent integration, flawless code generation and amazing reasoning abilities. I gave up on Anthropic.

Opencode is miles ahead due to the customization options, claude-code is great out of the box but it is a closed (limited) product. The only real competitor opencode has atm is Pi imho

I enjoy using OpenCode. I like the polished TUI and the native support for different models. The desktop app isn't too bad either.

I would have tested different harnesses with the same local model

OpenCode also has a plan mode, where it first goes through the repo and plans every change before implementing it. It works accessible with all models, by pressing TAB

@NeuralNine perhaps you didn't include Pi since vanilla Pi it is a bit raw for beginners, but, it also preserves tokens from initial context bloat. Nonetheless, for out-of-box tunable harnesses with solid core tools hash edit, write ,bash with outputsink, read with no subprocess overhead & extras like ast_*, ctx_* , lsp, debug, eval (persistent python for e.g.), subagents (yes, bloat, but useful for complex tasks) and solid Rust performance. Oh-my-pi is #1 for me.
