Perhaps some power user of Claude Code can enlighten me here, but why not just using OpenCode? I admit I've only briefly tried Claude Code, so perhaps there are unique features there stopping the switch, or some other form of lock-in.

Anthropic is actively blocking calls from anything but claude code for it's claude plans. At this point you either need to be taking part in the cat and mouse game to make that plan work with opencode or you need to be paying the much more expensive API prices.

i see

i guess they were blocking OpenCode for a reason

this will put people to the test that use mainly Anthropic, to have a second look at the results from other models
