GLM-5.3 Fast

The vendor's original weights, served unmodified on shared GPUs.

Stock models are the vendor's original weights, not abliterated: they keep the vendor's own refusals. Our safety check reads text only, so images and video sent to them are not screened. Prompts and outputs, images and video included, are never stored (privacy policy).
