GLM vs Claude, GPT, Gemini, Grok and DeepSeek: How Zhipu’s Open Model Compares
GLM-5.2 is the top open-weight model on the Artificial Analysis Intelligence Index, ranking 4th overall while costing a fraction of the closed flagships, and that gap is why the GLM vs Claude question has spread into a much bigger fight. Zhipu AI’s open-weight model costs $1.40 input / $4.40 output per million tokens against Claude Opus 4.8 at $5 / $25, ships under a permissive MIT license, and now trades benchmark wins with models from OpenAI, Google, xAI and DeepSeek. So the real question is not just GLM vs Claude. It is whether an open-weight model at a fraction of the cost can stand in for any of the big […]
