The best uncensored Z.ai model is GLM 5.2 (51.1 intelligence) — served without a provider-level moderation layer. GLM 5.1 (40.2) and GLM 5 (39.5) round out the top three.
Large language models served without a provider-level moderation layer, ranked by intelligence. "Uncensored" here means the API endpoint doesn't add its own filtering on top of the model — each model's own alignment training still applies, and open-weight entries can be self-hosted for full control. Relevant for fiction, roleplay, red-teaming and safety research, where an extra moderation layer causes over-refusal on legitimate prompts.
