Summary
Chinese AI startup Zhipu has released GLM 5.2, an open-source model that rivals top US models like Anthropic's Opus 4.8 on agentic benchmarks while costing roughly a fifth as much. Developer adoption is surging on platforms like OpenRouter, outpacing even DeepSeek's V4 launch. The article positions this as evidence that the AI competition is shifting toward intelligence-per-dollar efficiency, with open-source models becoming serious contenders against proprietary leaders like Anthropic and OpenAI.
