…nce baselines Converts the manually-run Kimi K3 eval tiers (sbatch-driven GSM8K sweep and MMMU-val) into repo-native accuracy-suite tests: - TestKimiK3 in accuracy/test_llm_api_pytorch.py: GSM8K at 16 GPUs (DEP16) in three modes (baseline / block-reuse / SA spec dec), each mirroring the corresponding examples/kimi_k3/eval_extra_llm_options*.yaml config. - TestKimiK3 in accuracy/test_llm_api_pytorch_multimodal.py: MMMU-val on the K3 VL checkpoint (KimiK3ForConditionalGeneration) with the kimi_k3_mmmu response-channel answer extractor, mirroring run_eval_kimi_k3.sbatch --task mmmu. - Reference baselines: GSM8K 96.5 (baseline + SA entries) and MMMU 84.89 under moonshotai/Kimi-K3 with quant_algo W4A16_MXFP4 (bf16 checkpoint with MXFP4-packed routed experts). These tests need 16 GPUs; no automated L0 stage schedules 16-GPU functional tests, so they are not added to any test-db list here. They self-gate via skip_less_mpi_world_size(16) and resolve <LLM_MODELS_ROOT>/Kimi-K3, skipping cleanly when the checkpoint is absent. Registration and run cadence are being coordinated with QA separately. Signed-off-by: Michal Guzek <mguzek@nvidia.com>
…ultinode list; capture AL/AR on the SA leg Lands the QA-agreed pieces from TRTLLM-15036 (QA answers by xinhe, 2026-08-19): - Register the four TestKimiK3 cases (GSM8K baseline/reuse/sa + MMMU) in tests/integration/test_lists/qa/llm_function_multinode.txt for the weekly QA multinode run. - The sa leg now records spec-dec acceptance per QA's rely-on-test-logs model: TLLM_EVAL_SPEC_STATS=1 logs the corpus AL/AR lines at eval end, and an iteration-stats AL is computed (enable_iter_perf_stats) and asserted via assert_acceptance_length. - acceptance_length.yaml gets the K3 entry: ref_al 1.318 (measured on the same workload through the lm-eval route, GSM8K draft_len 2, final weights) with min_al 1.15 as a deliberate acceptance-collapse tripwire (collapse reads as AL -> 1.0) rather than the usual 0.95*ref, since the two AL estimators may weight iterations differently; tighten after this test's first runs establish its own baseline. Signed-off-by: Michal Guzek <mguzek@nvidia.com>
…ssVar for evaluator kwargs - Annotate the two new TestKimiK3 test methods (params + None return) per the coding guidelines. - Annotate the multimodal TestKimiK3.EXTRA_EVALUATOR_KWARGS as ClassVar[dict] (Ruff RUF012). ClassVar over MappingProxyType because the consumer (accuracy_core.evaluate) types the parameter as Optional[dict] and only reads it as an update() source — no runtime change. Signed-off-by: Michal Guzek <mguzek@nvidia.com>
…e yamls Review feedback (CodeRabbit): gsm8k.yaml, mmmu.yaml, and acceptance_length.yaml carried no copyright header. Added the same two-line SPDX header the newer files in this directory already use (videomme.yaml, voxpopuli.yaml). Caveat noted for maintainers: the TRTLLM_POPULATE_ACCEPTANCE_LENGTH=1 populate path rewrites acceptance_length.yaml via yaml.safe_dump, which drops comments — whoever next populates a baseline should re-add the header (or teach the populate path to preserve it). Signed-off-by: Michal Guzek <mguzek@nvidia.com>
… to GB300-class memory Root causes from QA's first validation runs (DEBUG_LLM_FUNCTION_CLUSTER_TEST 1916 GB300, 1918 B200): - GB300 (all 7 failures, one cause): the engine loads fine, but llm.args.quant_config.quant_algo resolves to None for Kimi-K3 — the checkpoint carries its quantization as nested text_config.quantization_config (compressed-tensors MXFP4 experts), which the LLM-args layer does not surface, unlike modelopt-style hf_quant_config.json checkpoints (why the analogous K2.5 NVFP4 assert passes). Since accuracy_core.evaluate() matches reference entries against this same args-level field, both the assert and the yaml keys were wrong: the asserts are now inverted into a None reference-key contract (they fire if the args-level resolution ever changes, prompting a paired yaml-key update), and the moonshotai/Kimi-K3 entries in gsm8k.yaml/mmmu.yaml drop their quant_algo keys. - B200 (2h hang then the 7200s timeout, exit 124): QA ran the 16-rank world as 2 nodes x 8 B200 over InfiniBand. The last log lines show EP16 MoE communication bring-up: MNNVL/NVLink probing fails (no NVL72 fabric), DeepEP is selected, and init never completes. The 16-GPU K3 recipes are qualified on GB300 (one NVL72 domain) only, so both tests now gate on GB300-class device memory (skip_less_device_memory 200000: excludes 180-190 GiB B200/GB200, admits GB300) — wrong-platform runs skip in seconds instead of hanging for hours. Signed-off-by: Michal Guzek <mguzek@nvidia.com>
…300 exclusion From QA's second validation round (DEBUG_LLM_FUNCTION_CLUSTER_TEST 1928/1933): - GSM8K legs pass on GB300 under the auto-resolved KV cache manager V2 (the VL wrapper class inherits K2.5's V2 preference), validating the quant-contract fix and the AL capture. - The MMMU leg stalls on the same GB300 NVL72 topology: engine init and warmup complete, the eval starts, then all GPUs stop making progress until QA's watchdog kills the job. The qualified K3 MMMU configuration ran cache manager V1; the stall reproduces only at this test's long-generation shape (max_seq_len 24576, 16k-token outputs) under V2. Pin use_kv_cache_manager_v2=False for the MMMU test until the V2 x KDA-hybrid path is qualified at that shape; if the V1 rerun is green, the V2 stall gets filed as a product bug. - Extend the platform-gate comments: B300 clears the memory threshold but pairs 8-GPU nodes over InfiniBand (same non-NVL72 topology as the B200 hang), so it must be excluded via QA's platform selection.

Deleted lines have no post-image position, so TestsDefRule anchored them to the next surviving line and — finding module scope or the wrong YAML section — widened to file or dir level. Test-pruning PRs are entirely deletions, so they consistently pulled in most of L0: PR NVIDIA#18013 selected 45 of 110 blocks and 1344 test entries to verify the removal of a model that no longer exists anywhere in the tree. Read each side of a diff from the image that can answer for it: `+` lines from the post-image as before, `-` lines from the diff's own pre-image view, where a deleted class's `class` statement and a deleted YAML section's key line are directly visible. Pre-image line numbers stay unused because strip_noop_diff_lines drops blank/comment `-` lines and shifts them; attribution comes from in-hunk ordering instead. Both paths still fall back to file level when a deletion's owning scope lies outside its hunk. Four further narrowings, all of which previously reached file or dir level: - Decorator lines now belong to what they decorate, so editing @parametrize stays at method level and a class-level @skip_pre_blackwell stays at class level. - Resolving a reference-YAML change to no test is treated as zero impact rather than unresolvable, but only when the changed keys are also gone from the post-PR YAML — the shape of a pruning PR, which drops a reference and its test together. - acceptance_length.yaml keys tests as `TestC::test_m` rather than by HF model name, so its diffs never resolved; they now map to that method. - The accuracy class scan indexes by class name too, letting a class defined in several modules resolve to all of them. PR NVIDIA#18013 now selects 6 blocks / 22 stages / 26 entries, and NVIDIA#17922 1323 entries down to 26. Replaying the 18 tests-only PRs in the last 400 commits leaves 17 with an identical stage set and entry count, narrows one, and adds no stage anywhere.

…node post-merge CI Register the Kimi K3 GSM8K accuracy legs (added in NVIDIA#17922, previously run only by QA's weekly multinode pipeline) in the GB300 16-GPU 4-node post-merge stage introduced by NVIDIA#18363, so K3 accuracy regressions are caught by CI instead of surfacing a week later: - l0_gb300_multi_nodes_node4_gpu16.yml gains TestKimiK3::test_w4a16_mxfp4[baseline] and [sa], TIMEOUT (120) each (matching the stage's existing 16-GPU entry; tighten once real timings exist). The tests run as-is: the DEP16 configuration and its reference baselines are exactly what QA validated on 4x4 GB300. - The reuse and MMMU legs stay QA-weekly-only; the QA list keeps all four entries (same dual registration the stage's Qwen test uses). - Refresh the test docstring (it claimed no automated stage schedules 16-GPU tests) and note that the CI stage's gb300-only gpu wildcard also enforces the B300 exclusion. scripts/test_to_stage_mapping.py resolves both new entries to GB300-16_GPUs-4_Nodes-PyTorch-SingleNvlinkDomain-Post-Merge-1.

Summary
Adds Kimi K3 full-model accuracy coverage (GSM8K and MMMU-val) to the accuracy suite and registers it in QA's weekly multinode test list, per the QA agreement on TRTLLM-15036. The tests convert the previously sbatch/snippet-driven eval tiers of the K3 regression plan into repo-native pytest cases with checked-in reference baselines; the CI-porting side of this work is tracked under the TRTLLM-15035 epic.
Changes
TestKimiK3inaccuracy/test_llm_api_pytorch.py— GSM8K at 16 GPUs (DEP16: tp16 + attention-DP + EP16) in three parametrized modes matching the regression plan's sweep. Each mode mirrors the corresponding checked-in serving config (docstring pins this; keep in sync):baseline— CUDA graphs + overlap scheduler + chunked prefill on (mirrorsexamples/kimi_k3/eval_extra_llm_options.yaml)reuse— KV block reuse withmamba_state_config.periodic_snapshot_interval=256(mirrorseval_extra_llm_options_reuse.yaml; hybrid models expose reusable prefixes only at KDA state-snapshot boundaries)sa— suffix-automaton speculative decoding,max_draft_len=2, batch 8 (mirrorseval_extra_llm_options_sa.yaml)TestKimiK3inaccuracy/test_llm_api_pytorch_multimodal.py— MMMU-val on the K3 VL checkpoint (KimiK3ForConditionalGeneration), usingpost_process_fn=extract_kimi_k3_mmmu_answer(K3 reasons in its<|open|>response<|sep|>channel — the K2.5 strip-thinking extractor cannot see the answer) andpreserve_caller_max_tokens(lm-eval's 512-token MMMU default otherwise truncates the CoT before the channel opens). Mirrorsrun_eval_kimi_k3.sbatch --task mmmu(max_seq_len24576).moonshotai/Kimi-K3(quant_algo: W4A16_MXFP4— bf16 checkpoint with MXFP4-packed routed experts):references/gsm8k.yaml96.5 (baseline +spec_dec_algo: SAentries) andreferences/mmmu.yaml84.89.tests/integration/test_lists/qa/llm_function_multinode.txt(QA confirmed their multinode runner can execute accuracy-harness pytest, pending pipeline-script improvements on their side).saleg (per QA's rely-on-test-logs model):TLLM_EVAL_SPEC_STATS=1logs the corpus AL/AR (Spec-dec stats:lines) at eval end, and an iteration-stats AL is computed (enable_iter_perf_stats) and asserted viaassert_acceptance_lengthagainst a newreferences/acceptance_length.yamlentry.QA agreement (TRTLLM-15036)
qa/lists (QA's system of record); failures auto-file NVBugs.Reference provenance and first-run guidance
The baselines are measured priors from qualified runs of the same serving configs, but via the sbatch/
trtllm-evalroute — this pytest harness has not executed yet (no automated stage can schedule 16-GPU functional tests; CI here validates build/lint/collection only):examples/kimi_k3/README.md). The accuracy framework's hypothesis test gates ~3.2 pp below the reference, so a healthy run has wide margin.ref_al: 1.318(measured on the same workload via the lm-eval-route estimator) withmin_al: 1.15as a deliberate acceptance-collapse tripwire (collapse reads as AL → 1.0) rather than the usual0.95*ref, since the two AL estimators may weight iterations differently. Tighten after the first runs.Validation framing (merge-then-validate, per the QA process agreed on TRTLLM-15036): the first weekly QA run serves as the validation. Given the slack above, running gated is fine; alternatively, run the first pass with
TRTLLM_ACCURACY_NO_REFERENCE=1to record observed scores/AL/AR and the resolvedquant_algo(the in-test assert doubles as the reference-key contract) without gating, then confirm or adjust the reference entries via the usual NVBug-driven flow.🤖 Generated with Claude Code
