LGTM — the env-var and vllm serve flag additions are correct and match established patterns used in sibling MI355X scripts (e.g. VLLM_ROCM_QUICK_REDUCE_QUANTIZATION=INT4, AMDGCN_USE_BUFFER_OPS=1, --kv-cache-dtype fp8, --max-num-batched-tokens all appear with identical names/values elsewhere in the repo). The two flagged items (missing bilingual title/description, missing perf-changelog.yaml entry) are process/administrative gaps, not functional bugs in the script itself.
Extended reasoning...
Overview
The PR modifies a single shell script, minimaxm3_fp4_mi355x_vllm.sh, adding two env var exports (AMDGCN_USE_BUFFER_OPS=1, VLLM_ROCM_QUICK_REDUCE_QUANTIZATION=INT4) and two vllm serve flags (--max-num-batched-tokens 65536, --kv-cache-dtype fp8) to an existing AMD MI355X benchmark recipe. No new files, no logic branching, no config schema changes.
Security risks
None. This is a benchmark launch script; the additions are inference-engine tuning knobs (quantized cross-GPU reduction, buffer-op codegen, batched-token cap, KV-cache dtype) with no user input handling, no auth/crypto surface, and no external network calls beyond the existing vllm serve invocation.
Level of scrutiny
Low. I cross-checked the new env var names and flag values against sibling MI355X scripts (dsr1_fp4_mi355x.sh, minimaxm3_fp8_mi355x.sh, kimik2.5_fp4_mi355x.sh, dsv4_fp4_mi355x_vllm.sh, etc.) — every added token (VLLM_ROCM_QUICK_REDUCE_QUANTIZATION, AMDGCN_USE_BUFFER_OPS, --kv-cache-dtype fp8, --max-num-batched-tokens) already appears with identical spelling/values elsewhere in the repo, so this is a well-precedented, mechanical tuning change rather than a novel code path.
Other factors
The bug-hunting pass flagged two items: a missing bilingual title/description (a real but purely administrative policy gap per AGENTS.md) and a missing perf-changelog.yaml entry. On the changelog point, AGENTS.md's PR-label section clarifies that PR sweeps are gated by sweep labels (e.g. full-sweep-fail-fast), not by changelog edits — the changelog mainly matters for main-branch reuse/tracking — so while appending an entry mirroring the prior AITER-MoE entry for this same config-key (PR #1954) would be good practice, its absence doesn't block this PR's own validation. Given both findings are process nits rather than defects in the benchmark logic, and the script changes themselves are verified correct against existing conventions, I'm comfortable approving without requiring a human pass.

🔴 This PR adds new env vars (AMDGCN_USE_BUFFER_OPS, VLLM_ROCM_QUICK_REDUCE_QUANTIZATION) and vllm serve flags (--max-num-batched-tokens, --kv-cache-dtype) to this MI355X config but doesn't append a perf-changelog.yaml entry — the only changed file in the diff is this .sh script. Per AGENTS.md's "Updating Docker images" section, appending to perf-changelog.yaml is required because it's what triggers the CI benchmark sweep for a given config-key; without it, this perf-tuning change won't actually be exercised/validated by the sweep.
Extended reasoning...
The bug: The diff modifies benchmarks/single_node/fixed_seq_len/minimaxm3_fp4_mi355x_vllm.sh to add two new env vars (AMDGCN_USE_BUFFER_OPS=1, VLLM_ROCM_QUICK_REDUCE_QUANTIZATION=INT4) and two new vllm serve flags (--max-num-batched-tokens 65536, --kv-cache-dtype fp8) for the minimaxm3-fp4-mi355x-vllm config. The PR's changed-files list contains exactly one file — the script itself — with no corresponding entry appended to perf-changelog.yaml.
Why this matters: AGENTS.md's "Updating Docker images" section is explicit: "Update the image tag in the relevant configs/*-master.yaml and/or benchmarks/*.sh, update any related env vars / config params, and append a perf-changelog.yaml entry (required - triggers benchmarks)". Elsewhere the same doc reiterates: "Changes to perf-changelog.yaml trigger benchmark runs." In other words, the changelog isn't documentation-only — it's the mechanism the CI sweep infrastructure keys off of to decide which config to actually re-benchmark. A .sh-only change with no changelog entry means the sweep has no signal telling it this config needs to be re-validated.
Existing repo convention confirms this is the expected pattern for this exact config. perf-changelog.yaml already has a prior entry (around line 4344-4347) for minimaxm3-fp4-mi355x-vllm describing the same class of change — enabling AITER MoE via env vars (VLLM_ROCM_USE_AITER=1, etc.) plus a new --moe-backend aiter flag — which correctly appended a changelog entry documenting the toggle and citing the PR. This PR follows the identical pattern (env-var toggles + new serve flags) but omits the corresponding entry.
Concrete walkthrough of the failure mode:
- PR [AMD][MI355X] Update MinimaxM3 configs #2262 changes
minimaxm3_fp4_mi355x_vllm.shto enable Quick Reduce and tune two vLLM serving parameters — the PR description states this is exactly the point of the change ("Enabled Quick Reduce and tuned vLLM parameters"). - The PR is merged (or a sweep label is added) without touching
perf-changelog.yaml. - Because the CI benchmark trigger keys off changes to
perf-changelog.yaml(per AGENTS.md), and that file is untouched, there's no changelog-driven signal instructing the sweep to re-run/validate theminimaxm3-fp4-mi355x-vllmconfig with these new settings. - The result: the tuning this PR is entirely about is never actually benchmarked or validated by the automated sweep — silently defeating the stated purpose of the PR.
Fix: Append an entry to the end of perf-changelog.yaml (entries are chronological and must be appended, never inserted/prepended) with config-keys: [minimaxm3-fp4-mi355x-vllm], a description of the new env vars/flags (mirroring the style of the existing entry at line ~4344), and a pr-link back to this PR.

🟡 This PR's title and description do not follow the repo's mandatory bilingual policy: the title '[AMD][MI355X] Update MinimaxM3 configs' has no '/ <中文标题>' segment, and the description 'Enabled Quick Reduce and tuned vLLM parameters' has no accompanying Chinese translation section. Please update the title to ' / <中文标题>' format and add a Chinese translation (e.g. a section) to the body.
Extended reasoning...
AGENTS.md line 7 states, in mandatory language: "PR and GitHub-issue titles & descriptions must be bilingual — include a Simplified Chinese version in addition to English. Title format: <English title> / <中文标题>. In the PR/issue body, follow the English content with its Chinese translation (e.g. a ## 中文说明 section mirroring the summary...)". This is not a stylistic suggestion — it is phrased as a hard requirement ("must") that applies to "every PR and every issue."
The PR under review is titled [AMD][MI355X] Update MinimaxM3 configs. There is no / <中文标题> segment anywhere in the title, so the bilingual title format is not satisfied. The PR description reads only Enabled Quick Reduce and tuned vLLM parameters — a single English sentence with no accompanying 中文说明 section or Chinese translation of any kind.
The only carve-outs documented in AGENTS.md are narrow and don't apply here: agent-instruction files are explicitly English-only, the CODEOWNER sign-off template must stay English-verbatim (because the sign-off bot matches on the exact English phrase), and auto-generated bot comments follow their own workflow templates. The two timeline comments on this PR are indeed bot-generated (github-actions[bot], tagged <!-- recipe-reminder -->) and correctly fall under that bot-template exception — but they cannot satisfy the author's obligation to write a bilingual title/description, since they are static boilerplate unrelated to this specific change.
Step-by-step verification:
- Read AGENTS.md line 7 — confirms the bilingual requirement is mandatory and applies to "every PR and every issue."
- Read the PR metadata title:
[AMD][MI355X] Update MinimaxM3 configs— no/followed by Chinese characters present. - Read the PR description:
Enabled Quick Reduce and tuned vLLM parameters— a single English sentence, no Chinese content, no中文说明heading. - Cross-checked the two timeline comments — both are bot-authored recipe reminders (already bilingual themselves, by the bot's own template), not author-written content, so they don't fulfill the author's requirement.
- Checked AGENTS.md for exceptions — none of the listed exceptions (agent-instruction files, sign-off template, bot comments) cover a PR title or author-written description.
Impact: this is a documentation/process-compliance gap only — it does not affect the correctness of the benchmark script changes (Quick Reduce enablement, vLLM parameter tuning) and causes no build, test, or runtime failure. Fixing it is low-effort: rename the PR title to append / <中文标题>, and add a short ## 中文说明 section to the body summarizing the English description. Given the metadata-only nature and trivial fix, this should be treated as a nit rather than a blocking issue, even though the underlying rule is explicitly mandatory.
