ARC Evals finds 2023 agents far below autonomous replication threshold

ARC Evals tested four GPT-4- and Claude-based agents on 12 realistic autonomous replication and adaptation tasks. The agents completed only the easiest tasks and failed end-to-end persistent deployment and controlled phishing attempts, indicating that casual users of those versions were unlikely to create dangerous autonomous agents. OpenAI's GPT-4 system card independently documents ARC's predeployment evaluation role.

Why it moved the index

Away-from-doom magnitude 45: the controlled evaluation directly demonstrated that then-frontier GPT-4- and Claude-based agents could not complete the multi-step resource acquisition, persistence, and phishing tasks needed for dangerous autonomous replication, while documenting that stronger scaffolding and fine-tuning could narrow the gap. Confidence 87: the dated primary report publishes the tasks, agent design, failures, oversight, and limitations, and OpenAI's GPT-4 system card independently confirms ARC's predeployment evaluation role.
