Could it be tooling like Claude Code? I just used Claude Code with qwen3.5:35b running locally to track down two obscure bugs in new Common Lisp code I wrote yesterday.
Qwen seems fine for analysis to me, but Opus 4.6 is far better to use as a sounding board or for writing code
I use Claude Code as an orchestrator and have the agents use different models:
I use ollama pro $20/month and OpenAI $20/month. I have an Anthropic max plan at $100/month.
