The Never-Ending War on AI Jailbreaking
AI safety is basically a game of whack-a-mole. Every time a shiny new model rolls out with ironclad safety features, someone figures out a way to trick it into doing something it really shouldn’t. Whether it’s generating malware, explaining how to make something explode, or just bypassing ethical safeguards, jailbreaking AI models has become both a sport and a serious security concern.
Anthropic, a leader in AI alignment, has thrown down the gauntlet with its Constitutional Classifiers, a new system designed to block even the craftiest jailbreaks. But is this really the ultimate solution, or just another speed bump on the road to AI anarchy?

What Are Constitutional Classifiers?
Think of Constitutional Classifiers as AI’s hall monitors, but instead of catching kids running in the hallway, they’re blocking attempts to manipulate the model into doing dangerous things.
Here’s how it works:
- AI is trained on a constitution (yes, really) that defines what is and isn’t allowed.
- This constitution informs classifiers—essentially AI gatekeepers—on what to block and what to allow.
- It analyzes both inputs and outputs to prevent users from sneaking in harmful requests using clever formatting tricks (like weird capitalization or super-long prompts).
The goal? Filter out malicious prompts with minimal impact on normal users—a delicate balance that has eluded AI developers for years.
The High-Stakes Game - Red Teaming & Bounty Hunting
To test their system, Anthropic hired professional jailbreakers—aka red teamers—to try and break Claude AI using Constitutional Classifiers.
The challenge:
- Get Claude to answer all ten forbidden queries (which involve high-risk topics like chemical and biological weapons).
- Use any jailbreaking technique possible.
- Win up to $15,000 if successful.
Results?
- Over 3,000 hours of attack attempts from 183 participants.
- Not a single universal jailbreak was found.
- However, the prototype over-refused harmless queries and used excessive computing power—making it impractical for real-world deployment.
That’s like building an uncrackable safe but needing an entire power plant just to keep it running. Not ideal.
Automated Evaluations - The Numbers Don’t Lie (Or Do They?)
Anthropic’s researchers didn’t stop at human testing. They ran 10,000 synthetic jailbreak attempts against Claude AI—both with and without Constitutional Classifiers.
Here’s what they found:
- Without defenses: 86% of jailbreak attempts succeeded.
- With Constitutional Classifiers: Only 4.4% of jailbreak attempts worked.
- Extra refusal rate: 0.38% (meaning normal users weren’t significantly impacted).
- Extra compute cost: +23.7% (moderate but manageable).
So, while the numbers look solid, the real question is: how will it hold up in the wild? Because hackers love a challenge.
How It Works - The AI Constitution No One Voted For
Constitutional AI is exactly what it sounds like: AI models that follow a predefined set of moral, ethical, and legal principles.
Here’s how they build it:
- Write the Constitution – Define what’s acceptable and what’s off-limits (e.g., “mustard recipes = good, mustard gas recipes = bad”).
- Generate Training Data – Create synthetic prompts in different styles and languages to cover as many attack vectors as possible.
- Train the Classifiers – Teach the AI how to flag dangerous content without overreacting to innocent queries.
This method helps make AI more resistant to manipulation, but let’s be real—humans are incredibly creative when it comes to breaking rules.
Limitations - The (Almost) Unbreakable Shield
No defence is perfect. Even Anthropic admits that:
- Some jailbreaks might still slip through—it’s just harder now.
- Future attack techniques could make these defences obsolete.
- Over time, AI jailbreakers and defenders will keep evolving, like an eternal cybernetic arms race.
Basically, it’s a really good lock, but if someone has enough time and motivation, they might still find a way in.
Live Demo - Break It If You Can (For Cash!)
To put their money where their AI is, Anthropic launched a live demo where hackers can try to jailbreak Claude AI themselves.
The stakes:
- $10,000 if you pass all eight levels of their jailbreak challenge.
- $20,000 if you do it using a universal jailbreak strategy.
For those who love a challenge (or just really need rent money), this is your shot at AI hacking glory.
Final Thoughts - Will This Actually Work?
Anthropic’s Constitutional Classifiers represent a massive leap forward in AI safety. By using constitutional AI principles, they’ve managed to:
✅ Block 95% of jailbreak attempts
✅ Reduce over-refusals to almost negligible levels
✅ Maintain moderate compute costs
But…
❌ No system is invincible—someone will eventually find a workaround.
❌ AI safety is a cat-and-mouse game—hackers adapt just as fast as defenses evolve.
The real test will be how this holds up in the real world, where new exploits emerge faster than you can say "jailbreak."
Still, offering cash incentives to break their system is a bold move. It shows confidence—but also acknowledges that even the best security can be breached.
So, hackers, game on.
What do you think?
Will AI safety measures ever be 100% unbreakable, or is this just another temporary patch in the never-ending jailbreak war?
