Reddit's r/LocalLLaMA reports GLM-5.1 release with 362 upvotes and 89 comments. Z.ai's Li Zixuan posted 'Don't panic. GLM-5.1 will be open source' after community backlash over the closed-source GLM-5-Turbo launch (March 16). The base GLM-5 is a 744B MoE with 40B active parameters, MIT-licensed, trained on Huawei Ascend chips with no NVIDIA dependency. GLM-5-Turbo supports 200K context and 128K output — if 5.1 matches these specs as open-weight, it becomes the largest open MoE available.
