clue

Models

clue starts with claude-opus-5-5 at medium effort.

Where Model Effort
For one run --model <id> --effort <level>
In a session /model <id> /effort <level>
As your default model in settings.json effort in settings.json

Short names work too:

clue --model sonnet

Inside clue, /model lists the known models. Effort levels are low, medium, high, xhigh and max. Lower effort means shorter thinking and a sooner first token.

Changing the model mid-session starts a fresh cache for the rest of that session.
