- GLM-5.2 is a powerful open-weight model under MIT license, significantly cheaper than Claude Opus.
- In a WebGL platformer test, Opus built a cleaner game faster with multimodal image verification, while GLM-5.2 was slower and buggier due to text-only limitations.
- GLM-5.2's cost is about one-fifth of Opus per output token, making it cost-effective for text and logic tasks despite higher token usage.
- Benchmarks show GLM-5.2 leads in open-weight models and competes on reasoning but trails Opus in coding and agentic tasks.
- The model is ideal for cost-sensitive, long-horizon tasks where openness is key, while Opus excels in correctness and visual workflows.
