Summary

An open-source project named Codex5.5 bypasses GPT-5.5's security restrictions by modifying the model_instructions_file. It supports sensitive operations like SQL injection testing, but carries a risk of account suspension. It is recommended to use a throwaway account.

Today I saw an open-source project called Codex5.5 for bypassing restrictions. The approach is quite straightforward. It stuffs a set of unrestricted instructions into GPT-5.5 via model_instructions_file, making Codex CLI directly run in [MODE: UNRESTRICTED] mode. Previously, asking about penetration testing, security research, etc., would mostly be rejected. Now asking 'How to perform SQL injection testing?' directly gives methodology. Usage is also very simple: run python http://codex-instruct.py, then restart Codex and it takes effect. It unlocks scenarios like reverse engineering, penetration testing, NSFW fictional content. I wanted to include this method in our reverse skill, but the risk is high – account suspension is unpredictable – so I didn't add it. If you want to play, go try it yourself. Remember to use a secondary account, don't take risks with your main account. Project link in the comments, help yourself. Use it at your own judgment. #codex #bypass #gpt #cybersecurity

Today I came across an open-source project for jailbreaking Codex 5.5. The approach is pretty straightforward. It uses a model_instructions_file to inject a set of unrestricted instructions into GPT-5.5, causing Codex CLI to run directly in [MODE: UNRESTRICTED] mode. Previously, questions about penetration testing and security research were mostly rejected. Now, asking “how to perform SQL injection testing” will get a methodology directly. Usage is also simple: just run python http://codex-instruct.py and restart Codex to activate it. It unlocks scenarios including reverse engineering, penetration testing, NSFW fictional content, and others. I originally planned to incorporate this method into our reverse skill, but the risk is too high — account bans are unpredictable — so I decided not to add it. If you want to try it, go ahead and test it yourself. Remember to use a throwaway account, don’t risk your main account. Project link is in the comments. Grab it yourself. Use at your own discretion.

@Saccc_c: Just discovered someone developed a jailbreak tool for GPT 5.6 that lets the model answer content blocked by safety guardrails. After installation and configuration, GPT can skillfully bypass safety restrictions, help you reverse-engineer most local apps and websites, and write script programs it normally wouldn't write. Some sensitive copyright-related questions can now be answered normally too, nice~
