A Chinese open-weight model, GLM-5.2, now ranks among the world's three strongest large language models on independent benchmarks, trailing only two Anthropic systems and ahead of every model from OpenAI and Google. Released in mid-June by Z.ai, the Beijing developer formerly known as Zhipu AI, the model runs at as little as one-tenth the cost of leading American models, priced near $1.40 per million input tokens against roughly $15 for Claude Opus 4.8. Its release came days after the U.S. government ordered Anthropic to disable its two most powerful systems, Mythos and Fable. Independent testers at Artificial Analysis ranked the open-weight model third globally on a benchmark of real, economically valuable work. The model runs on domestic chips after the firm adapted its software following curbs on access to top Nvidia hardware. Z.ai's founder Tang Jie pushed back on claims that parity with American systems is a year away, while Elon Musk put it at early next year. Hardest reasoning tests still favor American labs, and U.S. firms have accused Chinese rivals of running tens of thousands of fake accounts and nearly 29 million queries to harvest model outputs. About 18 months ago DeepSeek matched U.S. systems at a sliver of the cost, and open models from China have since climbed past Google's and Meta's free releases.
