Not OC, but I tried OpenCode with Gemini, Claude and Kimi, and all of them were completely unable to solve any non-trivial problems which are not easily solved with some existing algorithm.

I understand how people use those tools if all they do is build CRUD endpoints and UIs for those endpoints (which is admittedly what most programmers probably do for their job). But for anything that requires any sort of problem solving skills, I don't understand how people use them. I feel like I live in a completely different world from some of the people who push agentic coding.

I'm using Claude Code with the latest version of Sonnet, using the official VS Code extension.

At my company they set it up that way.
