Zhipu AI drops open-source GLM-4.6V with native tool calling
Zhipu AI just open-sourced the GLM-4.6V series, offering a 106B flagship and a lightweight 9B Flash model under the MIT license. The standout upgrade is native multimodal tool calling, which lets agents feed raw images and screenshots straight into external tools without losing detail across a 128k context window. It gives developers an enterprise-ready open alternative.
