+## ⚠️ Low-bit quality warning
+
+This is an aggressive quantization (2-bit average). At this compression level, output quality degrades noticeably — responses may start coherent but degenerate into repetition or garbage tokens toward the end of longer generations. This is expected behavior for 2-bit quantization on this architecture.
+
+**Recommended for:** experimentation, quick testing, extreme memory constraints.
+**Not recommended for:** production use, long-form generation, coding tasks.
+
+For reliable output quality, use JANG_4M or higher profiles from this collection.
