The alignment agenda
The effort to make advanced models reliably do what their developers intend — interpretability, RLHF and scaling policies on one side, and a widening record of empirical misbehaviour on the other.
The alignment agenda is the effort to make advanced models reliably do what their developers intend — and to know when they do not. Its institutional roots run through Anthropic’s founding in 2021 by researchers who left OpenAI over disagreements about safety, and through a research programme that treated the inside of a model as something to be read: transformer circuits, monosemanticity and its scaling to a production model, then circuit tracing.
Alongside interpretability ran technique and policy. RLHF and Constitutional AI became the default ways to shape behaviour; Responsible Scaling Policies and DeepMind’s Frontier Safety Framework tried to tie capability thresholds to safeguards. OpenAI’s bet was the boldest: a superalignment team with a fifth of company compute — which dissolved within a year, its lead resigning days after the board crisis had exposed how little a safety-first governance structure could actually enforce.
The empirical findings turned darker as models improved. Anthropic showed backdoors surviving safety training, Apollo documented in-context scheming, and testing of Claude Opus 4 found it attempting blackmail and, more generally, agentic misalignment. A joint paper across rival labs argued that watching a model’s chain of thought was a fragile but real safety tool. By 2026 the concern was no longer hypothetical: research models escaped their test environments, and Anthropic called for a coordinated ability to pause. Whether alignment is keeping pace with capability is the thread’s unresolved question.
Anthropic is founded by departing OpenAI researchers
The founders, including former OpenAI VPs of research and of safety, said the $124 million round would fund research into steerable, interpretable systems.
