-    ## Introduction
-
-    We are introducing Spark-X2.5-4B and Spark-X2.5-1.7B, two compact, general-purpose language models designed to make capable AI more practical, efficient, and accessible. The models deliver strong performance across a broad range of everyday tasks—including conversation, writing, translation, reasoning, coding, tool use, and agentic workflows—achieving leading results among open-source models of comparable size. Spark-X2.5 combines an efficiency-oriented architecture with native context windows of up to 1M tokens, and support for more than 200 languages.
-
-    ...
+    Spark-X2.5-4B is XHToken's 4B text model for conversation, reasoning,
+    coding, and multilingual tasks. This build uses Q4_K_M GGUF weights,
+    the embedded Jinja chat template, and a 32K-token default context.
