Claude-like go-getter models?

So my workflow is heavily skewing towards Claude-like models, in the sense that they just "do things" and don't flap about it. OpenAI models are often like "ok I did this, I could do the next thing now, should I do that thing?" I've done some experimenting and Minimax seems to be like Claude, but it's a little lazy for long running tasks. I gave it some task with a json schema spec as output and at some point it just started rushing by entering null everywhere. And it was so proud of itself at the end, I couldn't be mad.
