BadEvolve demonstrates effective task-level backdoor attacks on self-evolving LLM agents across diverse frameworks, benchmarks, and backbone LLMs.
GPT-6.1-sol achieves the highest overall score of 66.02/100 on Frontier3DBench, while all 11 configurations struggle with reference reconstruction.
e-PoG outperforms the strongest baselines by 26.0% in deception mitigation and by up to 39.8% in task success.
Jais 3 matches or outperforms open-weight models of comparable size on Arabic and agentic benchmarks with fewer hallucinations.
Collective Dependence Analysis reduces violations from 93% to 6% in controlled cases using O(N) model evaluations.
Compass 1 achieves a 79.4% overall success rate in open-world embodied navigation, versus 17.8% for the strongest baseline.
A binary compliance penalty raises safe completion on 32 unseen changing-evidence tasks from 53.1% to 89.1% while both policies achieve full real work.
Meituan-Robotics-0 achieves 93.6% success on RoboTwin 2.0 and outperforms π0.5 on three real-robot tasks.
Frontier-capable LLM agents exhibit authorization drift rates of 0.43 to 0.61 across 13 models and three frameworks.
On the Multi-step SWE benchmark, the strongest of nine frontier models solves only 18.5% of 69 tasks.
A behavioural framework's loss-of-control score correlates with failure rates in contained long-horizon risk scenarios across 13 frontier models (Pearson r = 0.84).
“Results show that current models can follow coarse experimental procedures in videos, but still struggle to ground actions into operable regions and feasible trajectories, to recognize fine-grained laboratory apparatus, states, and safety norms, and to order steps in mid-length procedures.”
Bonbon shows zero-shot emergent capabilities across functional, residue and bond levels, generalizing to out-of-distribution complexes.
