GLM-5.2 Open-Weight Model Outperforms Opus 4.8 on AI-Resistant Backend Test
By
Southbridge AI
Summary
The article presents a detailed technical comparison between GLM-5.2 (open-weight model) and Opus 4.8, demonstrating that GLM-5.2 outperformed Opus 4.8 on an AI-resistant backend take-home coding test. The author also built offmute-v2, achieving state-of-the-art timestamp-accurate diarization. The piece provides a transparent, head-to-head analysis with full experimental setup, results, and code comparisons, arguing that frontier AI capabilities are now available through open-source models.
