+    B1-9B is Schneewolf Labs' Qwen3.5-based 9B model for reasoning and tool use.
+    It is trained to produce an answer after reasoning about tool results.
+    This Q4_K_M GGUF build includes the Q8_0 vision projector and uses an
+    8192-token context by default. A Q8_0 variant is also available.
