Remove Mixtral/Codestral/Pixtral and other out-of-scope Mistral family coverage per Test Scope Review 2026.7, keeping Ministral-8B, Mistral-Large-3-675B, and Mistral-Small-3.1-24B.

Dev Engineer Review

  • Removed out-of-scope Mixtral, Codestral, Mistral-7B, Mistral-NeMo, and related test configurations.
  • Retained coverage for Ministral-8B, Mistral-Large-3-675B, and Mistral-Small-3.1-24B.
  • Updated accuracy references, model registries, fixtures, benchmarks, and test lists consistently.
  • Replaced Mixtral quickstart coverage with supported Nemotron coverage.
  • No API or production-code changes were identified.
  • CI runs reported unstable or failed L0 pipelines. Review and rerun are required.

QA Engineer Review

Removed test coverage includes:

  • TestMistral7B, TestMixtral8x7B, and TestMixtral8x22B accuracy tests.
  • Mixtral routed-expert LoRA tests.
  • Codestral AutoDeploy accuracy coverage.
  • Mixtral modeling, smoke, tokenizer, multimodal, and end-to-end test cases.
  • The Mistral Small 4 tokenizer bridge test file.

The related CI and QA entries were removed from:

  • tests/integration/test_lists/qa/llm_function_core.txt
  • tests/integration/test_lists/test-db/l0_b200.yml
  • tests/integration/test_lists/test-db/l0_dgx_b300.yml
  • tests/integration/test_lists/test-db/l0_dgx_h100.yml
  • tests/integration/test_lists/test-db/l0_gb300_multi_gpus.yml
  • tests/integration/test_lists/test-db/l0_h100.yml
  • tests/integration/test_lists/waives.txt

The removed test-code coverage is represented in the affected CI or QA lists where applicable. Direct unit and smoke tests are not all listed individually. CBTS coverage data is unavailable.

Verdict: needs follow-up.

Walkthrough

The change removes selected Mistral, Mixtral, Codestral, and LLaVA test coverage and model mappings. It adds Mistral Small accuracy references, updates MoE benchmark examples to Qwen1.5-MoE, and changes the tokenizer test to Qwen3.

Changes

Model coverage cleanup

Layer / File(s) Summary
Accuracy and integration coverage pruning
tests/integration/defs/accuracy/*, tests/integration/defs/conftest.py, tests/integration/defs/test_e2e.py, tests/integration/defs/triton_server/conftest.py, tests/integration/test_lists/*, tests/test_common/llm_data.py
Selected Mistral, Mixtral, Codestral, and Mistral-Nemo accuracy references, fixtures, integration cases, scheduled tests, quickstart cases, and model mappings are removed. Mistral Small accuracy references are added, and one SM120 case uses Nemotron Super 49B.
MoE LoRA and benchmark cleanup
tests/integration/defs/llmapi/test_llm_api_pytorch_moe_lora.py, tests/integration/defs/perf/allowed_configs.py, tests/integration/test_lists/*, tests/microbenchmarks/bench_moe/*, tests/unittest/auto_deploy/singlegpu/smoke/*
Mixtral MoE LoRA, smoke, waiver, and performance configurations are removed. MoE guide examples now use qwen1.5_moe.
Multimodal coverage migration
tests/unittest/_torch/multimodal/test_find_num_image_tokens.py
LLaVA Next image and video handling is removed. Qwen2.5-VL and Qwen3-VL handling remains, with unsupported video models rejected explicitly.
Tokenizer test updates
tests/unittest/llmapi/test_llm.py
The tokenizer test changes from Mixtral to Qwen3/Qwen3-0.6B.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to 9e08c

This PR removes out-of-scope Mistral-family tests while retaining the specified coverage. A stale LLaVA reference may mislead future maintenance, but no actionable merge-blocking risk remains after normal checks and review.

Remove stale Mixtral entries from the QA list.

test_qwen_moe_routed_expert_multi_lora_varying_ranks is registered in test-db/l0_h100.yml and qa/llm_function_core.txt. Remove both deleted Mixtral entries from qa/llm_function_core.txt. No Mixtral references remain in test-db/ or waives.txt. Coverage for the retained test is sufficient.
