/model command returns only 4 choices for me: Opus 4.7, two Sonnet options and Haiku.
/model claude-opus-4-6[1M]
⎿ Set model to Opus 4.6 (1M context) · Billed as extra usage
Maybe this is becaus I'm on api pricing? (All new contracts for corps are pushed to that by Anthropic).
For anyone else who may want this, use: export ANTHROPIC_MODEL=claude-opus-4-6
