+# AstroLLM
+
+A domain-specialized language model for astronomy and astrophysics.
+
+**Retrieval-grounded. Tool-integrated. Openly built.**
+
+AstroLLM is building an open intelligence layer for astronomy — connecting
+the world's astronomical literature, databases, and observations through
+specialized language models that can retrieve, reason, cite, and teach.
+
+## What's coming
+
+- **AstroLLM Core** — Fine-tuned 4B/8B models for astronomy Q&A with citations
+- **Training datasets** — Curated SFT data from NASA ADS, SIMBAD, and the Exoplanet Archive
+- **Evaluation benchmarks** — Custom astronomy-specific eval suites
+
+## Built on
+
+NASA ADS · SIMBAD · NASA Exoplanet Archive · NED · PDS · Gaia
