Latent Space·4 hours ago·Benchmark
Zhipu AI's GLM-5.2 has passed broad informal community vibe checks, drawing favorable comparisons to GPT-class models and signaling a meaningful quality leap for open-weights AI. Z.ai, the company behind GLM, is additionally forecasting release of an open frontier-tier model — dubbed Open Fable — by December 2026. Together, these developments suggest open models are genuinely competing at the frontier rather than perpetually trailing closed proprietary systems.
