AI Insight
DeepInflation is an artificial intelligence agent that autonomously discovers and evaluates inflationary models in cosmology by combining Large Language Models with symbolic regression and a knowledge retrieval system. The system successfully identifies viable single-field slow-roll inflationary potentials that align with recent observational data, including ACT DR6 results, and can generate models matching specified cosmological parameters. The agent operates through natural language interaction, making complex inflationary model exploration accessible to both researchers and non-experts.
Why it matters
This tool represents a significant advance in automated scientific discovery, potentially accelerating cosmological research by rapidly exploring the vast landscape of inflationary theories. By democratizing access to complex model discovery through natural language interfaces, it could expand participation in theoretical cosmology beyond traditional expert circles.

Abstract: We present DeepInflation, an AI agent designed for research and model discovery in inflationary cosmology. Built upon a multi-agent architecture, DeepInflation integrates Large Language Models (LLMs) with a symbolic regression (SR) engine and a retrieval-augmented generation (RAG) knowledge base. This framework enables the agent to automatically explore and verify the vast landscape of inflationary potentials while grounding its outputs in established theoretical literature. We demonstrate that DeepInflation can successfully discover simple and viable single-field slow-roll inflationary potentials consistent with the latest observations (with the ACT DR6 results taken as an example) or any given $n_s$ and $r$, and provide accurate theoretical context for obscure inflationary scenarios. DeepInflation serves as a prototype for a new generation of autonomous scientific discovery engines in cosmology, which enables researchers and non-experts alike to explore the inflationary landscape using natural language.
