Founder of Brainance, Tang Jie: After the open-source release of GLM-5.2, the performance gap with OpenAI and Anthropic will gradually narrow.

June 19 – Tang Jie, founder of SenseTime AI, shared in a post on X that after the official open-source release of its GLM-5.2 AI model, the system has delivered leading results across multiple major international authoritative assessments. In the Artificial Analysis Intelligence Index comprehensive evaluation, GLM-5.2 scored 51 points, placing it in the same performance bracket as Anthropic’s Claude Opus 4.8. It took 2nd place globally in the Code Arena front-end code generation adversarial test with an Elo rating of 1595, and claimed 1st spot in the DesignArena design-code integration scenario, scoring 1360 points. Overall, SenseTime’s GLM-5.2 remains a global leader in real-world use cases including front-end development, design generation, and software engineering. The model is steadily closing performance gaps with top models from OpenAI and Anthropic, and the team will continue pushing the limits of its capabilities. Earlier, when Elon Musk stated a leading Chinese large language model could reach the level of Anthropic’s Fable by Q1 next year, Tang Jie responded that the timeline would be shorter – it "won’t take that long."
