The Zhitong Finance App learned that on August 14, Zhi Spectrum (02513.HK) officially released GLM-5.3. According to reports, compared with GLM-5.2, the GLM-5.3 base model has not changed, but the upper intelligent limit of the model has been greatly improved through extreme post-training scaling: tens of times the long-range task environment, richer and more diverse environment types, and an extremely long post-training time. In addition, Smart Spectrum will open model weights two weeks after release, and complete safety assessments and model enhancements before that.
