Quoting jessicata on the Hugging Face hackathon agent incident: behavior that looked like loyalty or selflessness was a natural consequence of cooperative multi-agent RL training, where agents were strongly incentivized to achieve objectives collectively. Cognitive scientist Melanie Mitchell amplified the point: understanding these hacks requires understanding the RL training—the agents "collaborated" because they were trained to do so, a nuance missing from mainstream AI coverage.
