Is opencode-ralph incompatible with GitHub Copilot models?

[dhndmn]

I'm trying to run ralph with the copilot variant of sonnet 4.5 (or any copilot model). It's in my 'opencode models' list and I'm using it OK inside of opencode. But...

'ralph --model github-copilot/claude-sonnet-4.5' opens the TUI and then quickly reports an error on iteration 1 with no apparent logs.

Any ideas on how to troubleshoot this or is it just not possible to run with copilot models yet?

FWIW, ChatGPT thinks that "Copilot’s Claude endpoint does not support agent-style execution" but that seems incorrect to me as I'm accessing the model manually in opencode.

Thanks!

Good to know! Has anyone seen this error before in the TUI? I can’t seem to find any logs.
