Z.ai's Open-Weight GLM-5.2 Beats GPT-5.5 on Long-Horizon Coding Benchmarks for a Sixth of the Cost

My take: Honestly, this one excites me, and let me tell you why. GLM-5.2 does not come from a Western lab and still beats GPT-5.5 on one of the toughest real-code benchmarks out there. It has 744 billion parameters, an MIT license (meaning it is open for anyone to use) and costs 1.40 dollars per million input tokens, against the over 7 dollars OpenAI charges for GPT-5.5. That is a sixth of the price, do the math. The model is from Z.ai (formerly Zhipu AI), which has spent years building top-tier open models. What strikes me most: the open-weight world is reaching the technical frontier faster than many expected, and that completely changes the conversation about who controls access to advanced AI. As someone who builds with AI without being an engineer, I celebrate anything that lowers the price of intelligence.
