Details
The Claude AI system, developed by Anthropic, is a large language model designed for general-purpose tasks. The latest version, Claude 4.5 Opus, has demonstrated a significant improvement in its long-term planning capabilities, as measured by the METR metric. METR stands for Mean Episodic Time Remaining, and it evaluates an AI's ability to plan and execute tasks over extended time horizons. The fact that Claude 4.5 Opus has achieved a METR time horizon of nearly 5 hours suggests that the system has made substantial advancements in its understanding of complex, multi-step problems and its ability to reason about long-term consequences of its actions.
