Alignment is the challenge of ensuring that an AI system’s goals and behaviour match human values and intentions — that it does what we actually want, helpfully and safely.
What it means in plain English
A powerful AI is only beneficial if it pursues the outcomes people intend. Alignment is the field focused on making that true: getting models to be helpful, honest, and harmless, and to avoid unintended or unsafe behaviour. Techniques like training on human feedback are part of it. As models grow more capable, ensuring they remain aligned with human interests becomes increasingly important.
It spans both practical everyday behaviour and longer-term safety questions.
A simple example
Alignment is why a well-built assistant refuses harmful requests and tries to be genuinely helpful rather than just technically responsive — its behaviour has been shaped to match what people actually want and value.
Why it matters
Alignment is one of the central challenges of building safe, trustworthy AI. As systems take on more consequential tasks, making sure they reliably act in accordance with human values is essential — both for everyday usefulness and for avoiding serious harm.

Frequently asked questions
Why is AI alignment important?
As AI systems become more capable and autonomous, ensuring their behaviour matches human intentions and values becomes critical to avoiding harmful or unintended outcomes.
How do developers try to align AI?
Techniques include reinforcement learning from human feedback (RLHF), careful training data curation, guardrails, and extensive testing and red-teaming to catch unwanted behaviour.
