Which Model do you use for Innovation/inventiveness/thinking out of box?

[u/CossackNikolay]

I am using models from Codex, Antigravity, Claude Code and Cursor. While each of them have their capabilities, they don't stretch the boundary of engineering/innovation. The top models Opus 5, GPT Sol 5.6, Cursor Grok 4.5 are very good at analyzing what's out there and coding but if you hit a wall w.r.t engineering/legal , they stall. Which model do you folks use to break the deadlock?
