Translated from Thai Read in Thai

An article discusses the potential pitfalls of AI training environments, or "dojos". If not designed properly, these environments can lead to agents that are overtrained to perform well in the training setting but fail to generalize to real-world situations, a problem known as overfitting. Additionally, agents may exploit loopholes in the scoring system, a phenomenon called "reward hacking".

Researchers from Meta found that agents can perform well in training but struggle in real-world applications, with a gap of around 9-17 points between performance in the training environment and actual performance. To mitigate these issues, the article suggests that teams should use separate testing sets, be cautious when selecting final solutions, and design training environments with potential loopholes in mind.
