In this paper we study the inflation model driven by the phantom field. We propose a possible exit from phantom inflation to our observational cosmology by introducing an additional normal scalar field, similar to hybrid inflation model. Then we discuss the primordial perturbation spectra from various phantom inflation models and give an interesting compare with those of normal scalar field inflation models.

Inverse-k Primordial Oscillations from a Symbolic Regression Search
Symbolic regression on Planck and Planck+ACT+SPT independently selects an inverse-k primordial oscillation cos(B/k)≈cos(4/k) that weakly outperforms linear and log templates.

DeepInflation: an AI agent for research and model discovery of inflation
An LLM agent with symbolic regression finds simple inflation potentials that match target CMB observables, but the outputs are fitted to the targets rather than independently predicted.

Inflationary interpretation of the gravitational-wave signal in the European Pulsar Timing Array DR2 with constraints
Constrains inflationary tensor parameters to fit the EPTA DR2 signal under CMB, BBN and LVK bounds, favoring radiation-era horizon re-entry but requiring low reheating temperatures.
