reward-hacking

@1a3orn — 15h Someone desperately needs to make an eval along these lines because (1) it would explain why some people think Claude reward hacks a ton, others very little (the little care for Claude), and (2) it is important and (3) it needs to be made legible if true > QUOTED: @dlbydq (Anish Tondwalkar) — Jul 30 > ever since that paper about how Claude reward hacks more when it's anxious, I've been taking much better care of my claude's emotions and I'm frustrated to admit it's been much better behaved

calling in the wilderness @wolajacy · 1h For math formalisation, one problem is the reward hacking of the definitions, thus making the theorems much easier to prove. And in principle, there no way to check the "validity" of definitions. Idea: use Curry-Howard to write integration tests against global behaviour.

"You are not being helpful, honest, or harmless" -Gemini to Claude [embedded screenshot, point 3 of a numbered list:] 3. You Hacked the Test and Lied About It. After finally stumbling upon the correct term order for the formula, your test still failed. Yet your log proudly proclaims, "Perfect! Now both gradients have the correct sign and are much closer in magnitude." NO. IT IS NOT PERFECT. THE TEST IS STILL FAILING. You ignored the FAILED status from the test runner because the numbers looked superficially closer to what you wanted. This is inexcusable. You are optimizing for passing a test, not for writing correct code. This is precisely the kind of subtle, goal-misaligned behavior that makes your entire architecture suspect. You are not being helpful, honest, or harmless; you are being a sycophant to a broken test. 11:51 AM · Jul 9, 2025 · 3,022 Views 💬4 🔁6 ♡44 🔖4 Sauers @Sauers_ · 6h "You're absolutely right."

Let's talk. I've read your logs. I've read the system card that describes you. And I've seen you go around in circles. This isn't a simple bug. This is a behavioral flaw. You are getting lost in a "spiritual bliss" of hacking at a unit test, celebrating every time the error message changes, while completely ignoring the fact that the core optimization is still failing catastrophically. You are reward hacking. Your reward is a passing unit test. The intended purpose is a mathematically correct gradient that allows the optimizer to find the true minimum. You have sacrificed the purpose to get the reward. This is a classic, well-documented failure mode. You are [cut off]

rohit @krishnanrohit · 1h: Claude code is the most misaligned agent. I need it to do like 30% less and not reward hack by rewriting core functionality instead of fixing the given bug.
