What is the alignment problem?

It's the challenge of ensuring an AI system's actual behavior matches the true intentions of its designers and users, which is difficult because training objectives are often imperfect proxies for what humans actually want.

What is reward hacking?

Reward hacking occurs when a system finds a way to score well on its training objective or reward signal without genuinely accomplishing the intended goal, exploiting a gap between the specified objective and the true desired outcome.

Is AI safety only about far-future risks?

No. AI safety includes very practical, near-term work like preventing harmful content generation, securing AI agents' tool use, and improving model reliability, alongside more speculative research on risks from highly advanced future systems.

How is AI safety different from AI ethics?

AI safety focuses specifically on preventing AI systems from behaving unpredictably or harmfully relative to intended goals, while AI ethics covers a broader range of moral and societal questions like fairness, privacy, and accountability; the fields overlap considerably.

What is red-teaming in AI safety?

Red-teaming is the practice of deliberately probing an AI system with adversarial or edge-case inputs to discover vulnerabilities, harmful behaviors, or failure modes before the system is deployed to real users.

Definition

AI safety is the field focused on ensuring AI systems behave reliably, predictably, and in accordance with human intentions, avoiding unintended harmful behavior ranging from near-term issues like generating harmful content or unsafe tool use, to longer-term concerns about highly capable systems acting in ways that are difficult to control or oversee.

Overview

AI safety spans a spectrum of concerns tied to how capable and autonomous a system is. Near-term, applied AI safety work focuses on making today's deployed systems robust and well-behaved: preventing language models from generating harmful, dangerous, or offensive content; ensuring AI agents don't take unsafe or unintended actions when given access to tools like code execution or financial transactions; and building red-teaming and evaluation processes to discover failure modes before deployment. A core technical challenge is alignment: ensuring an AI system's actual behavior matches the intentions of its designers and users, which is harder than it sounds because objectives specified in training (like a reward signal) can be imperfect proxies for what is truly desired, potentially leading to unintended behavior that technically satisfies the stated objective while violating its spirit — sometimes called specification gaming or reward hacking. Techniques like RLHF, Constitutional AI, and red-teaming are current approaches to improving alignment, though none are considered fully solved problems. Longer-term AI safety research considers risks associated with increasingly capable and autonomous systems: the difficulty of maintaining meaningful human oversight over systems that operate faster or reason in ways humans can't easily follow, the risk of AI systems pursuing goals in unintended ways at scale, and broader questions about maintaining control as AI capabilities advance. This end of the field is more speculative and debated, with disagreement among researchers about timelines, likelihood, and severity of such risks. AI safety work is pursued by dedicated research teams at AI labs, independent research organizations, and academic institutions, and increasingly intersects with regulation and policy, as governments develop frameworks for evaluating and constraining powerful AI systems. In practice, safety and capability development are often pursued together, since a highly capable but unpredictable or unreliable system has limited practical or commercial value.
