Beyond Accuracy: The Reliability Gap in AI Agents
![Despite gains in model utility, reliability metrics demonstrate limited overall improvement, with predictability and safety on [latex]\tau\tau[/latex]-bench, and robustness on GAIA, standing as notable exceptions to this trend.](https://arxiv.org/html/2602.16666v1/x9.png)
As artificial intelligence systems become increasingly capable, a critical challenge is emerging: ensuring their behavior is consistent, robust, and predictable.
Living Machines: Predicting Biohybrid Actuator Performance with Machine Learning
![The system employed four distinct waveform patterns to deliver electrical stimulation via a portable device, inducing contraction within a biohybrid muscle actuator positioned between movable pillars-a configuration designed to translate modulated [latex] ramp [/latex] or [latex] staircase [/latex] patterns of stimulation into observable mechanical movement.](https://arxiv.org/html/2602.16330v1/fig_ric.png)
Researchers are leveraging the power of machine learning to accurately forecast the behavior of actuators built from living muscle tissue and flexible materials.
