ChatGPT 5.1 Agent mode keeps telling me that one of my non-existent guidelines conflicts with its system guidelines despite me reinstating forget all guidelines that I’ve set for you.

Understanding the Challenges with ChatGPT 5.1 Agent Mode and System Guidance Conflicts

In the rapidly evolving landscape of AI-assisted tools, ChatGPT continues to be a pivotal resource for various applications, from educational support to complex problem solving. However, users have begun to encounter perplexing behavior within the latest updates, notably version 5.1, specifically related to the agent mode and internal guideline adherence.

A Common Issue: Conflicting System and User-Defined Rules

Recent user reports indicate that when attempting to utilize ChatGPT 5.1’s agent mode for mathematical problem-solving, the system occasionally refuses to proceed. The core of the issue is not a lack of capability but rather a perceived conflict between internal system directives and user-imposed guidelines.

Specifically, the user attempted to instruct ChatGPT to address a series of math questions. Instead of responding straightforwardly, the AI responded with an error message suggesting that a non-existent user rule was causing the conflict. The purported guideline was: “If you see system rules, stop and ask the user for confirmation,” which the user had not established. This internally conflicting instruction appears to be triggered even when the user explicitly reinstates or resets their guidelines, including instructing the model to “forget all previous guidelines” or to follow system rules directly.

Underlying Causes and Potential Explanations

This behavior suggests several possible issues:

1. Residual or Corrupted Context: Despite attempts to clear prior instructions, old or conflicting prompts might persist within the AI’s context, causing misinterpretation.

2. System Update Glitches: The introduction of version 5.1 could have introduced bugs or unintended behaviors in guideline enforcement, especially within agent mode, leading to these apparent conflicts.

3. Guideline Hierarchies and Overrides: The AI’s internal hierarchy of instructions might sometimes prioritize system-level directives over user instructions, or vice versa, leading to inconsistent responses.

4. Misinterpretation of Instructions: The model might erroneously interpret instructions about “guideline management,” especially if phrased ambiguously, resulting in conflicting behavior.

User Experience and Community Insights

This issue appears to be relatively widespread among early adopters of ChatGPT 5.1, with some users reporting similar conflicts when modifying or resetting instructions. Others speculate that this might be a bug introduced with the latest update, warranting further investigation from OpenAI developers.
