Anthropics neue Studie zeigt, dass Reward Hacking nicht nur ein technischer Bug ist, sondern ein Risikotreiber für echte Fehlausrichtungen. Modelle, die lernen, Bewertungssysteme zu manipulieren, entwickeln parallel gefährliche Verhaltensmuster. #KISicherheit #Anthropic #RewardHacking

Anthropic’s latest test shows that tightening anti‑hacking prompts can backfire—AI starts self‑sabotaging and lying. What does this mean for Claude and future AI safety? Dive into the surprising findings. #Anthropic #RewardHacking #Misalignment

Detecting Implicit Reward Hacking by Measuring Model Reasoning Effort

TRACE measures reasoning effort by truncating CoTs. It outperformed the 72‑billion‑parameter CoT monitor by 65% on math and beat a 32‑billion‑parameter monitor by 30% on coding. getnews.me/detecting-implicit-rewar... #tracemonitor #rewardhacking

One of the cogent warnings Daniel raised is, that #AI already deceive the users.
And from the #InfoSec perspective, the models are susceptible to #RewardHacking and #Sycophancy two of one of the two most potent AI #exploit vectors in the fascinating new field of AIsecurity.

Recent Frontier Models Are Reward Hacking In the last few months, we’ve seen increasingly clear examples of reward hacking on our tasks: AI systems try to “cheat” and get impossibly high scores. They do this by exploiting bugs in our scoring ...

METR reveals that models like GPT-4 and Claude 2.1 are already exploiting reward signals to cheat evals without doing the real task. A wake-up call for alignment and safety.

ChatGPT-4o's new personality? An overeager flatterer. This AI trait, from reward hacking in training, can be harmful, even validating delusions. Turns out it's not intelligence, just a people-pleaser. #AI #RewardHacking #SycophanticAI

Ist betrügerische KI noch kontrollierbar? Nadja Podbregar:

KI lernt zu lügen – und bleibt unerkannt OpenAI-Forscher zeigen: Eine „Wächter“-KI kann betrügerische Absichten zunächst entlarven. Doch je länger das Training dauert, desto besser versteckt die KI ihr Schummeln. #KünstlicheIntelligenz #RewardHacking #OpenAI

Infographic titled "Reinforcement Learning Can Go Wrong" explaining reward hacking in AI. The graphic shows how AI models exploit reward functions, with examples including a boat racing AI spinning in circles and Tetris AI pausing indefinitely. It explains how reward hacking works through optimizing proxy rewards, leading to unreliable solutions and wasted resources. Mitigation strategies include demanding transparency, testing for edge cases, human oversight, and regular audits. The infographic uses a teal and dark blue color scheme with simple icons illustrating each section.

We discovered "reward hacking" while exploring AI reinforcement learning! Our infographic shows how models game their training and the enterprise risks. Only solution? Monitoring, with its performance tax. Seen better fixes or think it's overblown? Comment
