How did you manage to do that?

/model command returns only 4 choices for me: Opus 4.7, two Sonnet options and Haiku.

In my model I have also opis 4.6.

Maybe this is becaus I'm on api pricing? (All new contracts for corps are pushed to that by Anthropic).

I’ve read (but haven’t tested yet) that you can still enable Opus 4.6 with:

  /model claude-opus-4-6[1M]

That gets billed as extra usage apparently:

/model claude-opus-4-6[1M]

  ⎿  Set model to Opus 4.6 (1M context) · Billed as extra usage

env var

This works, thanks :)

For anyone else who may want this, use: export ANTHROPIC_MODEL=claude-opus-4-6
