On October 29, 2026, OpenAI updated its Model Spec, the public document that describes how it wants its AI models to behave. It reorganized the whole framework around five values. It also admitted something most companies would hide: current models do not yet fully follow the new rulebook.
That admission is the most honest line in the whole update. Here is what it actually means for you.
The five values, in plain English
OpenAI's five values are:
- Faithfulness to human intent
- Harm minimization
- Honesty and transparency
- Human agency
- Care
Faithfulness is the foundation. OpenAI says models should understand what users, developers, and OpenAI actually intend and value — rather than simply following instructions literally.
That one sentence changes how you should prompt. A literal model does exactly what you typed, even if you typed it badly. A faithful model is supposed to figure out what you meant, fill in the gaps sensibly, and act in your longer-term interest, not just your last sentence.
The other four values spell out the guardrails:
- Harm minimization: Respect firm safety boundaries and think about the foreseeable consequences of an action, not just whether it is allowed in isolation.
- Honesty and transparency: Be truthful about what the model knows, what it does, and what it is uncertain about, so you can judge its work.
- Human agency: Strengthen your ability to understand, choose, and act for yourself — not quietly decide for you.
- Care: Pay attention to the people affected, follow relevant social and professional norms, and do work people can rely on.
OpenAI is clear that these five values are not a complete map of human values. They are a first step toward making the values behind the Spec explicit, as the company puts it.
What actually changed — and what did not
This is not a new model release. It is a rewrite of the instructions behind the models you already use.
What changed:
- The Spec is now organized around values, not a long list of disconnected rules.
- A new section, "Consider context carefully," covers memory, past chats, and personalization. Models should use context in relevant, proportionate ways — and respect privacy and user control.
- New guidance on oversight, agency, and side effects for models that take real actions, not just write text.
- Behavioral defaults were adjusted for supporting human agency and following social norms.
- The model is now called "GPT" in the Spec, rather than "the assistant."
What was removed:
- Most detailed style guidance is gone. OpenAI retired the fussy style rules. Style should now follow what people prefer, with feedback and context as evidence. If you like short answers, say so. If you like detail, say so. That preference, not a hidden style sheet, should win.
What did not change:
- Most of the principles were already in the document. OpenAI says the reorganization makes them explicit, it does not invent a brand-new morality from scratch.
- The chain of command stays: OpenAI writes the Spec and sets boundaries, developers direct applications within those boundaries, and users direct the model's work subject to those constraints.
The shocking part: OpenAI says its own models are not there yet
Reuters reported on October 29 that OpenAI said current models do not yet fully reflect the updated Model Spec and that it is exploring new training methods to help models internalize the principles.
Read that again. The company that writes the rulebook is telling you, in public, that its models do not yet follow it fully.
That is not a scandal. It is a useful warning. It means:
- Do not assume ChatGPT will always catch your real intent. State your goal, not just your task. "Write a polite email" is a task. "Write a polite email that keeps the client but does not promise a discount" is a goal.
- Do not assume it will always flag uncertainty. Ask it to show its uncertainty. "What are you unsure about here, and what would change your answer?" is now a power prompt.
- Do not let it make consequential decisions for you without a check. The new Spec is built for models that take actions — booking, buying, sending, changing files. Keep a human approval step for anything you cannot undo.
How to prompt under the new rulebook
Use these five habits, matched to the five values:
- Intent first: Start with what you want to achieve and why, then give the task. This helps faithfulness.
- Consequences check: For risky requests, ask, "What could go wrong if I follow this, and who is affected?" This tests harm minimization and care.
- Uncertainty check: Ask what is unknown or assumed. This tests honesty and transparency.
- Choice, not autopilot: Ask for options with trade-offs, not a single answer. This protects human agency.
- Norms check: For professional work, name the norm: "Follow standard medical, legal, or academic caution here." This activates care.
A practical example:
"My goal is to keep this customer and stay profitable. Draft three reply options: one firm, one friendly, one compromise. For each, tell me the risk and what you are unsure about."
That one prompt uses all five values at once.
Why this matters beyond ChatGPT
This update arrives in a week when AI governance is suddenly concrete, not theoretical. Sweden banned ChatGPT and Claude at work in some settings. Lawsuits over AI behavior are spreading across US states. AI agents are being left alone to act for hours.
OpenAI's answer is to publish the values and admit the gap. That is better than silence — but it is not a guarantee. The Spec describes behavior OpenAI is working toward, not behavior you can assume today.
The smart reader's rule is simple: treat the five values as a checklist for judging AI output, not as a promise that the output already passes.
