Zhipu: glm-4.7-flashx:free

GLM-4.7 is Zhipu AI's 2026 flagship model, featuring a 355B parameter Mixture-of-Experts (MoE) architecture. Its signature innovation is the "Interleaved Thinking" system, which enables the model to reason before every response and tool call, ensuring unparalleled instruction adherence. It has gained fame as the premier engine for "Vibe Coding," capable of translating vague creative descriptions into aesthetically superior, production-ready UI/UX. Ranking top among open-weight models on SWE-bench, it rivals proprietary giants like Claude 3.5 Sonnet in autonomous software engineering and complex agentic workflows.
