i think it's a feature - you can choose reasoning effort when you select a model for the first time. after that changing effort requires editing config

I think you can still change the variant with either
<cmd> or <ctrl> + tor directly from the command dialog.bnn1 commentedon May 18, 2026
@simonklee you're right, it's called variants in opencode. it is a bit unfamiliar considering most other harnesses use
/effort. thanks!glorious73 commentedon Aug 23, 2026
Thanks, but it is unfortunate to have to go to a github issue to learn that.
