# Qwen3-Omni v1-v6 Run Lineage

Generated: `2026-06-21T11:47:45+00:00`.

Scope: Verified public-safe Qwen3-Omni LoRA/eval packages over the selected Xperience-10M 128-episode surface.

Interpretation rule: Do not confuse the Qwen run versions with the project evidence lines. The project evidence lines are one public sample episode and selected 128-episode artifacts. Qwen v1-v6 are only the Qwen3-Omni run lineage inside the selected-128 line. The 20-task matrix uses Qwen3-Omni v6 LoRA; v5 remains the pinned prior release; v1-v4 are lineage and ablation evidence.

Read the versions as an engineering audit trail, not as six separate benchmark
rows. v1-v4 explain how the Qwen3-Omni pipeline was hardened, v5 is the pinned
prior multiscale release, and v6 is the current 20-task Qwen3-Omni row.

## Compact Lineage

| Version | Run | Purpose | Change from previous | Eval samples | JSON validity | Action macro-F1 | Contact acc. | Use now |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| v1 | Selected-128 validation-aware LoRA baseline | Prove that the selected-128 split, LoRA training, held-out eval, validation, and public packaging loop works end to end. | First verified Qwen3-Omni selected-128 LoRA run. | 448 | 0.8750 | 0.0027 | 0.6451 | Use only as lineage evidence for the first working pipeline. |
| v2 | Structured-JSON reuse full-8-GPU LoRA | Make the answer format schema-checked and reduce invalid JSON before expanding scale. | Reused the selected-128 split with a stricter structured-JSON answer contract and full 8-GPU LoRA training. | 448 | 0.9978 | 0.0024 | 0.7188 | Use as evidence that schema-constrained evaluation improved validity and contact accuracy over v1. |
| v3 | Strict-label prompt evaluation | Separate prompt/eval formatting effects from adapter-training effects. | Evaluated the v2 adapter with stricter labels and prompts; no new adapter training. | 448 | 1.0000 | 0.0022 | 0.7210 | Use as prompt/eval ablation evidence, not as a separate trained model. |
| v4 | Four-epoch structured-JSON LoRA | Test whether longer structured-JSON LoRA training improves the same selected split. | Trained a new four-epoch full-8-GPU LoRA adapter on the structured-JSON setup. | 448 | 1.0000 | 0.0019 | 0.7299 | Use as overfit and metric-tradeoff evidence before the multiscale export. |
| v5 | Multiscale cap96 LoRA | Move from the 448-sample compact eval to a denser multiscale 4,032-sample held-out eval. | Introduced the multiscale cap96 export and larger held-out evaluation surface. | 4032 | 1.0000 | 0.0023 | 0.7865 | Use as the pinned prior release; it remains stronger on JSON validity, subtask, next-action, object, and transition metrics. |
| v6 | Rank64 lr5e-5 multiscale LoRA | Promote the current public Qwen3-Omni 20-task row with multiscale LoRA plus task-specific probes. | Kept the multiscale setup, changed LoRA rank/lr to rank64/lr5e-5, and added verified task-specific probes for full 20-task coverage. | 4032 | 0.9990 | 0.0029 | 0.8177 | Use as the current public 20-task Qwen row; it improves action macro-F1 and contact accuracy while v5 remains the prior comparator. |
