Tines launched 3B at the end of July, and its entire pitch is that you can vibe code safely, as credentials never touch generated code. API keys live in connectors and get injected by a proxy outside the execution environment, so the model writing your workflow can’t read them even if you ask it to. I said I’d be testing this with a local model, and providing your own model is what the free tier expects after you use your $50 credit allowance. I suspect that most will bring their own cloud-based subscription, but I was especially curious how a local LLM would handle it instead.
