+# MiniMax-M3 MXFP8 H100 AgentX (agentic-coding) recipe with EAGLE3 speculative
+# decoding — the spec-decoding=mtp variant of agentic/minimaxm3_fp8_h100.sh.
+# Everything outside the speculative block mirrors the non-MTP agentic sibling
+# (Mooncake host-DRAM KV offload, --block-size 128, --language-model-only,
+# --kv-cache-dtype fp8, TRITON_ATTN, minimax_m3 parsers, vllm-router for
+# DP-attention), so the spec-decode delta is readable at equal concurrency.
+#
+# Speculative config: the current Inferact/MiniMax-M3-EAGLE3-GQA draft head
+# with three speculative tokens and the committed thinking-on golden AL.
+#
+# The drafter is pinned to FLASH_ATTN, as on every CUDA MiniMax-M3 MTP recipe:
+# the EAGLE3 head is MHA and FlashInfer only serves page size 128 through its
+# trtllm-gen kernel, which requires GQA/MQA. FLASH_ATTN accepts any
+# multiple-of-16 block size, so the mandatory 128 is fine for the draft. (The
+# ROCm recipes need no pin because their server runs TRITON_ATTN throughout.)
+#
+# Throughput runs pin synthetic acceptance to the committed golden AL; the
+# EVAL_ONLY accuracy run keeps real target verification. See SYNTHETIC_ACCEPT_LEN.
