there already some tools out there could do so, the user have to provide his/her own APIs.
imagine if cursor do the same (yes it used 2-3x more the credit),
but each time, you can SWITCH among LLMs, that will be wonderful.
As i found sometimes 1 LLM work better for some e.g. c3.7 better for
graphics/physic while G2.5Pro for other things.
oops… seems someone discussed about multi agents before,
similar.
