GLM-5.2 Ships 753B Open Weights. My GTX 1660 Holds 6 GB.
In mid-June 2026 Z.ai shipped GLM-5.2, a 753-billion-parameter open-weight model that runs roughly even with GPT-5.5 on long-horizon coding. The card on my desk holds 6 GB. After months of running Gemma 3 4B vision on a GTX 1660, this is the real cost of self-hosting open models in VRAM, latency, and quality.
