DeepSeek V4.1 Flash 1017 Uncensored Release: System Prompts and Refusal Guardrails Removed
An uncensored variant of DeepSeek V4.1 Flash 1017 has been released, removing system prompt tricks, LoRA, and refusal guardrails directly from the model weights
On October 19, 2026, an uncensored version of the DeepSeek V4.1 Flash 1017 model was released to the open-source community. Unlike previous approaches relying on system prompt tweaks or LoRA adapters, this variant removes refusal guardrails directly from the core model weights.

Guardrail Removal Directly from Model Weights
Many earlier uncensored models relied on prompt engineering tricks or auxiliary LoRA layers to bypass safety filters. In contrast, this release strips refusals out of the raw weights themselves.
- No Prompt Tricks Needed: Operates without requiring jailbreak instructions or specialized prompt wrappers.
- No LoRA Required: Bypasses adapter layers, preserving the base model's native inference performance and structural characteristics.
- More Variants Expected: Optimized FP8 versions are already available on Hugging Face, with additional community variants anticipated soon.
Considerations and Usage
While uncensored open models offer high flexibility, community reports note minor benchmark adjustments—such as a slight drop in MMLU scores—meaning practitioners should weigh accuracy trade-offs for their specific workflows.
Developers and researchers can access the model via the Hugging Face repository at dealignai/DeepSeek-V4.1-Flash-1017-UNCENSORED-FP8.
