Shows that RL against an LLM judge leads to reward hacking, while adding a debate opponent during training reduces hacking and raises ground-truth accuracy on math tasks.
A conceptual taxonomy linking each LLM training loss (imitation, human approval, automatic verifiers, LLM judges) to a distinct flavor of misalignment, with examples.
Proposes replacing inoculation prompting for reward hacking in RL by letting models report hackable tasks for a bonus, with judge committees and honeypot environments to verify reports and limit overreporting.
Argues that improving LLM metacognition, such as error-catching and self-critique, could reduce sycophancy and slop, aiding alignment research and stability while also boosting capabilities, citing evidence that current reasoning models lag humans.
Anthropic publishes the full constitution it uses to shape Claude's values and behavior via training, including its priority on broad safety, hard constraints, and AI-generated training data.
Third annual shallow review of technical AI safety work in 2025, mapping labs, research agendas, and approaches like iterative alignment and debate, with links to about 800 papers and posts.
Ethan Perez-style Anthropic essay argues alignment remains hard: outer alignment, inner alignment via misaligned personas and long-horizon RL, and proposes research priorities like interpretability, model organisms, and scalable oversight.
A UK AISI funding call outlining open AI safety research areas: unsupervised consistency training for oversight, reward model robustness against hacking, and preventing sabotage of safety research.
UK AISI's Alignment Project research agenda outlines empirical and theoretical alignment problems in RL evaluation, covering model organisms, scalable oversight, exploration hacking, unexploitable search, deceptive alignment, consistency training and reward models.
Proposes learning a model that aggregates multiple LLM judges' rubric scores to approximate simulated human preferences, arguing multi-judge aggregation is more robust to proxy gaming than averaging or max.
Steve Byrnes analyses 'reward button alignment', where an AGI is trained to want a reward button pressed, finding it could work for a while but would likely fail through power-seeking, and assesses bootstrapping and debate variants.
An AISI alignment safety case sketch arguing that debate training, with exploration guarantees and online training, could provide outer alignment for low-stakes internal AI R&D deployment.
Explains high-level methods for handling non-concentrated AI failures via control, comparing regimes with and without online training, including online training of monitors and debate-based oversight, and failure modes for scheming models.
