Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🔵 Low · up to The PR adds resumable campaign execution and durable result publication. It is mergeable with explicit owner awareness because unusual configuration reuse or an interrupted or concurrent run could weaken trajectory provenance or leave result records temporarily inconsistent; follow-up should document ownership and recovery expectations.

### What does this PR do? This PR adds repeatable Qwen 3.5 vision evaluation options for quick comparisons and complete benchmark runs. Teacher and student models receive the same predefined inputs, and each result records which evaluation path and example set were used. It is stacked on [PR 2304](#2304), which adds the Qwen 3.5 0.8B campaign and its result-record foundation. The available options are: - **Small comparison set:** 344 predefined examples from RealWorldQA, MMMU, and MVBench. This is a quick regression check, not a full benchmark evaluation. - **Broad comparison set:** 690 predefined examples from eight supported benchmarks. Prefer this for future short comparisons when all datasets are available. It is also a subsample. - **Complete evaluation:** every available example from those eight benchmarks, with no sample limit. Benchmarks that require an external judge remain separate. The general vLLM path runs the model through vLLM. The Qwen-specific path loads it directly through Transformers. They prepare prompts and videos differently, so their scores describe the complete paths, not only the inference engine. The Qwen-specific path temporarily pins a separate upstream `lmms-eval` revision for Qwen 3.5 support. Follow-up work should move both paths to the evaluator supplied by the worker image. The recorded teacher baselines use this structure. The unexplained 4B general-vLLM MVBench result needs follow-up before it is used as a comparison reference. The old misleading evaluation name remains only as a compatibility alias. ### Testing Automated checks cover the evaluation definitions, both model-loading paths, split workloads, and compatibility behavior. The broad comparison set and complete evaluation are defined but have not yet been run. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **New Features** - Added versioned Qwen 3.5 VLM evaluation profiles supporting vLLM and native execution. - Added short, full, exact-row, task-selection, and shard-based evaluation options. - Added native Qwen 3.5 support with disabled-thinking chat templates and backend-specific validation. - Added deterministic preflight checks, profile fingerprints, standardized result schemas, and richer run metadata. - **Documentation** - Updated setup guidance, profile coverage, limitations, and result interpretation. - Added documented Qwen 3.5 teacher evaluation records for 0.8B and 4B models. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: Johannes Rausch <jrausch@nvidia.com>
What does this PR do?
Type of change: new example
This adds a Qwen 3.5 0.8B VLM Puzzletron campaign for searching and materializing pruned students, training them with KD, evaluating checkpoints against one teacher, and writing reproducible result records. It also packages measurements from the earlier prototype run and labels that run's custom selection policy as superseded.
Campaign design
Attention and GDN pruning are not included in this recipe.
Results and limitations
The included results came from an earlier prototype campaign that used a custom shortlist. Those student selections were produced by the historical policy, not the corrected recipe. The corrected recipe has not yet been rerun to produce new results.
