Continual-ARC benchmark: top coding agents fail to learn from experience, a fine-tuned 9B model doesn't

CodeByPoonam · x · 2026-11-12

Unify.ai released Continual-ARC, a new benchmark testing whether agents can memorize from experience and generalize. OpenClaw, Hermes Agent, and Prime Agent all failed to meaningfully learn from experience — none memorized anything of value or generalized to new tasks, instead re-reading the repo every session. In contrast, training a small 9B model's weights achieved both memorization and generalization. The result highlights a fundamental gap in current agent architectures around continual learning.
