+# Serve unsloth/Qwen3.8-27B-UD-Q8_K_XL as frank-default-large with a
+# z-lab DFlash2 drafter (Qwen3.8-27B-DFlash2-Q4_K_M) on the Vulkan backend.
+#
+# Runtime: upstream llama.cpp PR #27342 (DFlash2 support) built with
+# GGML_VULKAN=ON for the Strix Halo gfx1151 (RADV). DFlash2 selects its
+# candidates through TOP_K + ARGMAX ops that the HIP backend does not
+# implement, so the whole stack runs on Vulkan0.
+#
+# The target and the drafter share the Qwen3.8 arch. DFlash is lossless
+# under strict rejection sampling. --spec-draft-n-max clamps to the drafter's
+# trained block size (8).
+#
+# Tunables come from frank-default-large.env in this directory unless
+# FRANK_LARGE_ENV_FILE overrides that path.
