+![Invoking synclaude with the interactive i subcommand to override the default models. First question is how to override the models, selecting each individually or by group. After selecting group, the next question is which group, large -L or light -l or both. After selecting large, the next question is which model to use, presented as a list of IDs with fuzzy filtering. After typing "mmm2" for MiniMax M2, last question is whether to save those as default. After selecting No, Claude Code starts.
