GLM 5.3 Flash Uncensored
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. We serve it on hardware we operate inside the EEA; prompts and completions are not stored.

Which GLM 5.3 is this?
GLM 5.3 Flash Uncensored runs on our own hardware without storing prompts or completions: dealignai's build of the 320B GLM-5.3-Flash with refusals removed in the weights, image input kept. GLM 5.3 Uncensored is dealignai's build of the full 753B GLM-5.3, text only; we serve it through a partner provider with zero data retention. Both are meant for security research and red-teaming and need your own moderation in front of end users.
GLM 5.3 and GLM 5.3 Flash are Z.ai's official models; we serve them through a partner provider, without zero data retention.
Licence: what it means for your company
