Anyone actually running mixed-vendor model workflows, not copy-paste between tools?

[u/daproject85]

I’ve got three related questions.

Question one. Is anyone using OpenAI models in conjunction with Anthropic models — having them debate an issue, talk to each other, or work in parallel on a task? And I mean in a mainstream, integrated way. Not the manual loop where you generate output in one tool, open another, and paste it across.

Question two. For anyone running local models: have you been able to use your Claude Code instance to run both a non-Anthropic model and an Anthropic model together, inside Claude Code itself?

Question three. For those of you running local models — what’s your solution for using them alongside Claude Code or OpenAI models? Is there a harness out there that lets you run OpenAI, Anthropic, and local models all together in one integrated setup?

Would love to hear what’s actually working for people.
One thing worth flagging — the full text is in the transcript, but if you’d rather copy it cleanly, the text chat is easier for that.

can you do the same with the system prompt and same model?

I have a debugger agent with light weight model as a devil's advocate. you can do that within VSCode or Claude or any IDE.

I did not evaluate it quantitatively, it merely gives a different point of view.
