**Z.ai** launched **GLM-5.3-Flash**, a natively multimodal model with a **1M-token context window**, **320B total parameters / 18B active parameters**, under the **MIT License**. It is positioned as a price-competitive successor to GLM-5.2 and claims performance on par with **Claude Opus 4.8** on coding tasks. The model is available via weights on **Hugging Face**, API, chat, coding plan, and AutoClaw, and runs entirely on Chinese AI chips. Early third-party support includes **CoreWeave** and **Baseten**. Independent evaluation by Artificial Analysis scored GLM-5.3-Flash **57 on their Intelligence Index**. Community reactions highlight its potential as a best intelligence-per-dollar option, though some critique its vision capabilities.
