A new analysis of cosmological data suggests that spatial curvature and dynamical dark energy could resolve the tension between inflationary model predictions and current observations of the spectral index $n_s$. Traditionally, the standard cosmological model $\Lambda$CDM shows a slight discrepancy with inflationary models such as Starobinsky, Higgs, and the simplest $α$-attractors. This study proposes that by considering a universe with a small negative spatial curvature or time-evolving dark energy, this tension is significantly alleviated.
