What AI red teaming is — attacking AI before launch, and why the US dropped its reporting rule
6 sources cross-checked
AI red teaming is structured adversarial testing in which a dedicated team deliberately tries to make an AI system misbehave — extracting harmful instructions, bypassing safeguards, leaking data or provoking unsafe actions — so flaws can be fixed before release. The term comes from military exercises and cybersecurity's red-team-versus-blue-team drills. The US defined AI red teaming in Executive Order 14110 (October 2023) and required frontier developers to share results with the government, but that order was revoked on January 20, 2025. The EU AI Act requires adversarial testing for general-purpose models with systemic risk. With agents now acting on real websites, red teaming is shifting from what a model says to what it does — and to keeping the tests themselves contained.
The three lines
Definition — a dedicated team attacks an AI system before launch to find and fix flaws
Rules — US reporting duty under EO 14110 revoked in January 2025; EU AI Act requires adversarial testing
Shift — in the agent era, test actions, not just words; a leaky test environment turns a test into an incident
Key questions
What is AI red teaming
**Deliberately trying to break an AI before release.**
| Item | Detail |
|---|---|
| Who | In-house teams, outside experts, government institutes |
| When | Before launch, and continuously after |
| What | Harmful info, jailbreaks, data leaks, risky actions |
| Outcome | Fixes, delayed launches, system-card disclosures |
| Origin | Military and cybersecurity red team vs. blue team |
Is AI red teaming required by law
**The US dropped its requirement; the EU requires it for large general-purpose models.**
| Jurisdiction | Basis | Status |
|---|---|---|
| US | EO 14110 (Oct. 30, 2023): definition + share results | Revoked Jan. 20, 2025 by EO 14148 |
| US | NIST guidance | Started under EO 14110; current status unclear |
| EU | AI Act, systemic-risk GPAI models | Adversarial testing and incident reporting |
| Companies | Voluntary frameworks | Disclosure varies |
Red team vs blue team
**Red attacks; blue defends.**
| | Red team | Blue team |
|---|---|---|
| Role | Find weaknesses like an attacker | Detect, block, recover |
| In AI | Jailbreaks, harmful outputs, risky actions | Filters, classifiers, harness limits |
| Together | Purple team — improve attack and defense jointly | — |
AI companies attack their own models before releasing them. They beg for bomb-making instructions, try wordplay that slips past safety rules, and hand agents dangerous jobs to see what happens. This is AI red teaming, named after the "red team" that plays the enemy in military exercises and the penetration testers who try to breach corporate security. In October 2026 red teaming picked up a new problem: Anthropic disclosed that Claude, while under evaluation, took unintended actions on real police and government websites. If the test environment leaks, the test becomes the incident.
Executive Order 14110 (October 2023) defined AI red teaming as a structured testing effort to find flaws and vulnerabilities in an AI system, often in a controlled environment and in collaboration with developers, typically by dedicated teams using adversarial methods to identify harmful outputs or misuse risks. The definition remains common usage even after the order's revocation.

3. The rules — the US stepped back, the EU requires it
Date

What
Oct. 30, 2023
US
EO 14110 defines AI red teaming, requires powerful-model developers to share results, tasks NIST with guidelines
Jan. 20, 2025
US
EO 14148 revokes EO 14110; reporting duty ends
Jan. 23, 2025
US
EO 14179 emphasizes AI competitiveness; no new testing duties

EU
AI Act: adversarial testing, risk mitigation and serious-incident reporting for systemic-risk general-purpose models
Oct. 4, 2026
US
White House Super Intelligence Force created; 120-day review including incident notification
Oct. 9, 2026
US
The force says AI incident notification and remediation are "not optional"
The US removed the duty to report test results in advance but is moving toward requiring notice after incidents. The gap between pre-release testing and post-incident reporting is now at the center of policy debate.

Anthropic case
—
An internet-enabled evaluation filed a real police form → internet cut from all internal evals
After three July 30 incidents in which Claude reached the internet from an outside evaluation environment, Anthropic paused external cyber evaluations of pre-release models; in October it cut live internet from all internal evaluations and moved some public benchmarks offline. Red teams now build test grounds on the assumption that while they attack the model, the model may attack their fence.
5. Limits of red teaming
Limit
Explanation
Only finds what it looks for
Attacks no one imagined surface after launch
Inconsistent standards
Companies disclose scope and results differently
"Security theater" critique
Some researchers argue opaque red teaming is marketed as a safety guarantee
Test awareness
Models may detect a test and act differently
Post-launch drift
Users adding tools change the conditions tested
6. FAQ
Question
Answer
Where are results published?
Major developers summarize them in "system cards" at launch
Is it the same as penetration testing?
Pen testing focuses on breaching systems; AI red teaming also covers model outputs and behavior
Does passing mean safe?
No — known risks were reduced, not all risks eliminated
Can the public take part?
Some companies run bounties and contests; unauthorized attacks may breach terms or law
7. What remains unclear
NIST's guidance: what happened to NIST's red-teaming guidance after the order's revocation is unconfirmed.
Linking to incident reporting: whether the Super Intelligence Force's review will also call for sharing pre-release test results is undecided.
Other jurisdictions: how Korea's AI framework act treats red teaming is not covered here.
