GLM-5.3-Flash Uncensored (NVFP4)
GLM-5.3-Flash Uncensored is a community build of GLM-5.3-Flash (dealignai, MIT licence) with refusal behaviour removed by a permanent weight edit — no fine-tuning and no prompt tricks; the vision input is kept. It was released for alignment and safety research, and its card reports no refusals on a standard harmful-request benchmark, so anything user-facing needs your own moderation. The model is currently offline; the card stays for reference.
