 **Reading the gradations:**
 
-- **Privacy:** *architectural* (Tinfoil) beats *policy-based* (GreenPT, PublicAI). An
-  enclave protects you even if the provider is compromised; a policy protects
-  you only as far as the provider keeps its word. Both are better than a
-  provider with neither.
-- **Green energy:** *100% renewable* (GreenPT) beats *undisclosed* (Tinfoil,
-  PublicAI). GreenPT reports its energy mix; the others do not, so we can't
-  claim greenness for them.
-- **Sovereignty:** *publicly developed* (PublicAI) is its own value — the models
-  come from public/national AI programs, built as public goods rather than
-  proprietary products. It's a third axis, independent of privacy and energy.

+
+`🌱 regolo/qwen-image` (Regolo, EU-hosted, zero data retention) generates
+images from a text prompt. In the chat, use the 🎨 button and describe what
+you want — no prompt engineering needed. Via the API:

+```bash
+curl https://gateway.inference.coop/v1/images/generations \
+  -H "Authorization: Bearer ***" \
+  -H "Content-Type: application/json" \
+  -d '{"model": "regolo/qwen-image", "prompt": "a watercolor painting of a mountain lake", "n": 1, "size": "512x512"}'

+The response returns base64-encoded JPEG(s). Billed per pixel generated.
