I agree completely, I meant in terms of opensource ones only. Opus 4.5 is the current SOTA and using it in Claude Code is an absolute amazing experience. But, paying 0 to test GLM-4.7 with opencode, feels like an amazing deal! I don’t use it for work though. But to keep “gaining experience” with these agents and tools, it’s by far the best option out there from all I’ve tried.
