Motivation

Add disaggregated inference (DI) and MTP (EAGLE speculative decoding) deployment commands for Qwen3.5-FP8 on AMD MI355X to the cookbook page, and bump the MI355X docker image to v0.5.16.

This aligns with InferenceX PR SemiAnalysisAI/InferenceX#2557 which adds the corresponding benchmark configurations.

Changes

  • docs/cookbook/autoregressive/Qwen/Qwen3.5.mdx:
    • MI355X docker image: lmsysorg/sglang-rocm:v0.5.15.post1-rocm720-mi35x-20260715lmsysorg/sglang:v0.5.16-rocm720-mi35x
    • New: Disaggregated Inference (MoRI 1P1D) commands — TP4 prefill + TP8 decode (12 GPUs), delivering 24-31% better throughput/GPU vs TP8P+TP8D (16 GPUs) with identical decode interactivity
    • New: DI + MTP (EAGLE) commands — EAGLE speculative decoding (depth 3) on the TP4P+TP8D topology, with guidance to switch decode to TP4 at conc≥128 to avoid MTP throughput collapse (+83% throughput/GPU improvement)

Notes

  • The previous cookbook PR (#31454) bumped images; this PR adds the DI/MTP deployment recipes that were missing.
  • Disaggregated inference commands use --disaggregation-mode prefill/decode and --disaggregation-transfer-backend mori.

…to v0.5.16

- Bump AMD MI355X docker image from v0.5.15.post1-rocm720-mi35x-20260715
  to lmsysorg/sglang:v0.5.16-rocm720-mi35x
- Add disaggregated inference (MoRI 1P1D) deployment commands for MI355X:
  TP4 prefill + TP8 decode (12 GPUs), which delivers 24-31% better
  throughput/GPU vs TP8P+TP8D (16 GPUs) with identical interactivity
- Add DI + MTP (EAGLE speculative decoding) deployment commands:
  EAGLE depth 3 on TP4P+TP8D, with guidance to switch decode to TP4
  at conc≥128 to avoid MTP throughput collapse

Aligns with InferenceX PR SemiAnalysisAI/InferenceX#2557.
