I Was WRONG About GLM-5.2: Opus-Level AI at Home?

I tested Z.AI GLM-5.2 in Claude Code UltraCode Mode against Claude Opus, GPT-5.5, and frontier-model workflows for real technical planning and implementation work. Was I wrong about GLM-5.2? Have Chinese labs open source, open weights models caught up with frontier American labs? Use any model in Claude Code Ultracode mode (automatic workflows + subagents):    • Use Claude Code Ultracode Mode With ANY Lo...   I think open-source, open-weights models have finally turned a corner. With big brother coming in and revoking access to top AI models, it couldn't have come soon enough (see: government took away anthropic claude mythos / fable -    • Claude Mythos /  Fable 5 Was BANNED. This ...   ) Z.ai's GLM5.2 in Claude Code Ultracode Mode is insane. Bonkers. Legit. GOATed. #ZAI #GLM52 #openai #LocalAI #AIAgents #Opus #Fable #ClaudeCode #gpt #AgenticAI #LLM #AI #artificialintelligence
