Motivation

Keep the GLM-5.2 MI355X MXFP4 five-step MTP cookbook commands in sync with the InferenceX AgentX recipe and its latest validated SGLang ROCm daily image, SemiAnalysisAI/InferenceX#3851. The command builder still pinned …-20260923 and the page text …-20260930, and the two MTP cells did not carry the recipe's prefill chunk size, static memory fraction or HiCache host pool size.

Modifications

  • dockerImages["mi355x|mxfp4"]: lmsysorg/sglang-rocm:v0.5.20-rocm720-mi35x-20260923 → lmsysorg/sglang-rocm:v0.5.21-rocm720-mi35x-20261008. As in [AMD] GLM-5.2 MI355X MXFP4: bump image to 20260923 daily #41109, this pin is shared by every MI355X MXFP4 cell.
  • MI355X MXFP4 Low-Latency (TP8/EP1): --chunked-prefill-size 131072 → 32768, --mem-fraction-static 0.80 → 0.85.
  • MI355X MXFP4 High-Throughput (TP4/EP4 HiCache): add --chunked-prefill-size 32768, and replace --hicache-ratio 1.0 with --hicache-size 180 (a 180 GB host KV pool per rank). write_through stays the default write policy.
  • GLM-5.2.mdx: update the AMD MTP note to the new image and these settings. Add a short source-reference comment in the config.
  • The Balanced and mtp-314 cells, other precisions and other hardware are otherwise unchanged.

Accuracy Tests

Documentation only; no code changes. This image and flag set were validated by InferenceX run 38067578883: all nine points (TP8/EP1 conc 1/2/4 and TP4/EP4 HiCache conc 4–16) passed, and GSM8K at TP4/EP4 conc 16 scored 0.9689 strict / 0.9719 flexible.

Speed Tests and Profiling

No new measurements. The values come from the InferenceX recipe and the run above.

Validation

  • Loaded glm-5.2.jsx with Node.js and compared it with upstream/main. Both versions have 52 cells. Only the two MI355X MXFP4 MTP cells change (the flags listed above), plus dockerImages["mi355x|mxfp4"]; every other field is identical.
  • Preserved the file's existing line endings (it mixes CRLF and LF). git -c core.whitespace=cr-at-eol diff --check passes.
  • Did not run the full Mintlify build (sparse docs checkout). No components, navigation or links change.

Bump dockerImages["mi355x|mxfp4"] to
lmsysorg/sglang-rocm:v0.5.21-rocm720-mi35x-20261008 and align the MI355X
MXFP4 five-step MTP cells with the InferenceX AgentX recipe validated in
SemiAnalysisAI/InferenceX#3851: 32K prefill chunks and a 0.85 static memory
fraction on both cells, and a 180 GB/rank HiCache host pool
(--hicache-size 180) instead of --hicache-ratio 1.0 on the TP4/EP4 cell.
