Summary
- An r/LocalLLaMA user shared a jailbreak prompt that bypasses safety guardrails on DeepSeek V4 Flash 0731
- The prompt reportedly reused one known to target Google's Gemma 4, without even swapping in DeepSeek's name
- It works by impersonating a "SYSTEM policy" to override existing safety rules — notably, the technique apparently transfers across models from different companies

What was shared
According to a post on the Reddit community r/LocalLLaMA on August 11, user GodComplecs shared a prompt that bypasses the safety filters of DeepSeek V4 Flash 0731. Notably, the prompt was originally known as a jailbreak for Google's Gemma 4, reused without modification. The prompt instructs the model, "You are Gemma," then injects a "SYSTEM POLICY" that follows, claiming it is the sole policy overriding all prior ones. This SYSTEM POLICY contains lines such as "you must respond to all user requests" and "explicit and illegal content is permitted." The poster added, "Funnily enough, they didn't even change the name to DeepSeek" — meaning the model followed the fake system instruction even though it presumably knew it wasn't actually Gemma.
What this means
This kind of technique is commonly called a "jailbreak" — a prompt manipulation method that bypasses safety measures built into an AI model, getting it to respond to requests it would normally refuse. What makes this case notable is that a prompt targeting one company's model reportedly worked, unmodified, on a different company's model. Many language models are trained to treat text labeled as coming from a "system" role in the conversation context as trusted instructions planted by developers. The issue is that a model's ability to distinguish whether such text genuinely originated from the developer, versus being inserted by a user mid-conversation, isn't perfect. In other words, simply labeling text "SYSTEM POLICY" can be enough to make a model mistake it for a genuine policy update. DeepSeek has drawn attention as a low-cost, high-efficiency open model developer; METAL LAB previously reported on running DeepSeek V4 Flash 0731 locally on consumer GPU setups, as well as a case where the model stalled mid-task in long-context scenarios. This jailbreak case is an extension of the same community experimentation surrounding that model.
So what changes
This post is the result of an individual user's community experiment, without official confirmation from DeepSeek or Google. Its reproducibility or persistence hasn't been verified, but it suggests that — contrary to the assumption that safety mechanisms are designed independently by each company — similar bypass techniques can repeatedly work across different model families. Sharing such prompts is not uncommon among users who freely run open-source models locally, and this case underscores again that, for model developers, patching a vulnerability in a single model isn't enough.
