Closest replacement for Claude + Claude Code? (got banned, no explanation)

I was using Claude Pro + Claude Code pretty heavily (terminal workflow, file access, etc.) and my account just got banned with zero explanation. From what I’m seeing, this isn’t that uncommon - people getting flagged without clear reasons or responses - so I’m trying to move on and rebuild my setup. What I’m looking for is something that actually matches BOTH sides of what Claude gave me: 1. Claude-level reasoning / writing strong long-form thinking structured outputs (planning, creative work, etc.) 2.
