with omp 18.2.3, you can mention a model with ^ to turn it into a spawnable subagent!
we received many requests for allowing the model to be specified in Task invocations, but accepting arbitrary IDs are tricky: agents then end up picking outdated/arbitrary models when it's not specified + it also opens up the ability to use, say, openrouter over a codex subscription.
it's rather experimental, but let's see how folks like this take on the UX!
+ as it's not widely known, little protip: you can press alt+p twice to change the model backing the default subagent type!
