Claude Code's handling of multiple choice questions is awfully nice (it uses an interactive interface to let you use arrows to select answers, and supports multiple answers). I haven't seen opencode do that yet, although I don't know if that's just a model integration issue -- I've only tried with GLM 4.7, GPT 5.1 Codex Mini, and GPT 5.2 Codex.

Opencode also has that feature, I've seen it multiple times in the last days (mostly using Opus 4.5/4.6/Gemini 3)
