+    TwIL-LM3 is a 3B SmolLM3-based reasoning model specialized for formal
+    logic, entailment, semantic parsing, and Lean formalization. This default
+    entry uses the publisher's recommended Q4_K_M GGUF and supports a 65K-token
+    context window. A higher-quality Q8_0 build is available as a variant.
