Using "ollama launch claude" locally with qwen3.5:27b, telling claude to write code it thinks about it then stops, but doesn't write any code?

Apple M2, 24 GB memory, Sonoma 14.5. Installed ollama and claude today. Pulled qwen3.5:27b, did "ollama launch claude" in my code's directory. It's an Elixir language project. I prompted it to write a test script for an Elixir module in my code, it said it understands the assignment, will write the code, does a bunch of thinking and doesn't write anything. I'm new to this, I see something about a plan mode vs a build mode but I'm not sure if it's the model, my setup or just me.
