China's GLM-5.2 challenges GPT-5.5 and Claude Opus on coding benchmarks

Zhipu AI's GLM-5.2, a Chinese frontier model, has reportedly achieved strong performance on coding benchmarks, surpassing OpenAI's GPT-5.5 and Anthropic's Claude Opus 4.7. On the FrontierSWE benchmark, GLM-5.2 scored 74.4%, narrowly trailing Claude Opus 4.8 but outperforming GPT-5.5. The model also demonstrated significant gains on Terminal-Bench 2.1 and matches the coding capabilities of leading proprietary models, while being available as an open-source option. AI

IMPACT Sets new SOTA on coding benchmarks, challenging leading proprietary models and potentially accelerating the adoption of open-source alternatives.
