## Notes

Still sold on Z.ai (with FlashX and free Flash variants) but superseded by the natively multimodal GLM-5.3-Flash. Model id casing on Z.ai assumed lowercase glm-4.6v (listed as GLM-4.6V). Release day not verified (HF 2025-12-07).

Open-weight (MIT) vision-language GLM; cheapest/free Z.ai vision option via GLM-4.6V-Flash.
