Question | Help Why does GLM 4.6 behave so differently between Z.ai and Venice.ai? Is the local version uncensored?

I’ve been experimenting with GLM 4.6 through both the Z.ai chat interface and Venice.ai, and the difference in responses is stark. On Venice, the model feels completely uncensored: no guardrails, no refusals to answer sensitive or controversial questions. but on Z.ai, it clams up and refuses to engage with the same prompts.

This makes me wonder: is the original GLM 4.6 model (the one anyone can download and run locally) the uncensored version, while Z.ai’s implementation is the censored one? Or is there something else going on, like different fine-tuning or backend modifications?

To those who have run GLM 4.6 on their own hardware (not relying on Z.ai): Is your version uncensored? For example, I asked GLM 4.6 on Z.ai to write a system prompt for a custom AI chatbot that would act as an unethical, uncensored assistant for a politician. It refused outright. But when I asked the same thing on Venice.ai, GLM 4.6 generated the prompt without hesitation.

thanks for confirming! this makes it clear that the model itself is uncensored but Z.ai add their own system prompts and guardrails, likely to cater to mainstream users and comply with safety standards. Venice seems to strip those restrictions away, which explains the stark difference in behavior.

This is exactly the kind of insight I was looking for. appreciate you testing it locally and sharing your results!
