+### About the Apertus models
+
+Apertus is the **Swiss AI Initiative's** open foundation model, built by a
+public collaboration between **EPFL, ETH Zurich, and the Swiss National
+Supercomputing Centre (CSCS)**. It's "fully open" in the strict sense — not just
+downloadable weights:
+
+- **Open weights & code** — released under the **Apache-2.0** license, so anyone
+  can use, modify, and redistribute it, commercially or not.
+- **Open training data** — trained only on *fully open* data (unlike most
+  proprietary models, which keep their training set secret). The data, code,
+  methods, and alignment principles are all published and reproducible.
+- **Open values** — governed by a public **Apertus Charter** that documents the
+  model's values and principles rather than leaving them implicit.
+- **Sovereign & public-good** — designed to European data-protection norms
+  (GDPR, EU AI Act, Swiss law) as an example of "AI as a public good," not a
+  proprietary product. Trained across 1,500+ languages (40% non-English).
+
+The v1.5 generation adds image understanding, a longer 262K-token context
+window, improved tool use, and instruction-following. It's the *publicly
+developed* counterpart to the private (Tinfoil) and renewable (GreenPT)
+offerings — sovereignty as a third axis of member choice.
