The author compared two models, GLM-5.2 and Opus 4.8, in a take-home designed to be AI-resistant and found GLM to be more accurate and maintainable. GLM's version of offmute-v2, a multi-step pipeline that fuses a regular STT model with a multimodal LLM, outperformed Opus in several areas, including transcription quality, speaker identification, and instruction-following.
