Yeah I agree. I’m “vibe engineering” an entire (non-trivial) programming language, toolchain, and standard library, as well as some smaller side projects. I leave OpenCode implementing entire milestones unattended for long periods regularly.

I feel like I’d need to not have a job or a life if I wanted to exhaust the OpenAI $100 plan using GPT 5.5 xhigh, and I’ve found it insanely capable.

That said, while I don’t read the code much (if at all), I do discuss each milestone up front to make a plan, and use/dogfood the results to direct any follow-ups and refinements, which puts a natural cap on the ratio of LLM contributions to my input for these side projects. I believe these human parts are still necessary not to eventually end up with a mess.
