Jevvideo OneJev-4B H200 LoRA Adapters
LoRA adapter set for the Jevvideo long-video frame-selection agent, trained on 8xH200 from OmniJev/OneJev-4B. Ships controller, grounding, and verifier adapters plus per-role metrics and five-benchmark results.

Highlights
- Three deployed LoRA adapters: controller, grounding (locator + frame selector), and verifier.
- Base model OmniJev/OneJev-4B; LoRA r=16, alpha=32, dropout 0.0 on attention and MLP layers.
- Five-benchmark mean 63.54; LVBench 54.01 versus 40.44 for uniform-32-frame sampling.
- Each adapter directory holds trainable.pt (~130 MB) and base_model.json; not plug-and-play PEFT adapters.
- Needs the Jevvideo pipeline plus a frozen Qwen3-VL-8B reader to run end to end.
Questions about this entry
Short answers drawn from the linked project or page.
The adapters are loaded by the Jevvideo codebase, which drives a window-tree navigation over a long video, and a frozen Qwen3-VL-8B reader answers from 32 frames (16 overview plus 16 kept). The reader is used off the shelf and is not included in this repository.
Base is OmniJev/OneJev-4B at revision c88e18653ceb7a8770716287f55fdefc79d6b588. LoRA is r=16, alpha=32, dropout 0.0, applied to attention (q/k/v/o, in_proj_*, out_proj) and MLP (gate/up/down_proj) across all layers.
End-to-end accuracy over 10,759 of 10,760 questions: CG-Bench mini 51.87, MLVU M-avg 76.38, LongVideoBench 66.87, Video-MME overall 68.56, LVBench 54.01, for a five-benchmark mean of 63.54. Video-MME by duration is short 79.44, medium 69.11, long 57.11.
The repository is publicly accessible but gated: you must log in or sign up and accept the conditions to access the files. The license is listed as other. It is not deployed by any Inference Provider.
adapters/{controller,grounding,verifier}/ each contain trainable.pt and base_model.json. Results live in results/<role>_metrics.jsonl, <role>_run_info.json and <role>_early_stopped.json, with configs in config/<role>_config.yaml, h200.yaml, formal_1103.yaml and version.env.
Against a uniform-32-frame baseline using the same reader, paired per question, the agent scores 54.01 versus 40.44, a +13.57-point gain with 95% CI [10.82, 16.20]. 338 questions are answered only by the agent, versus 128 only by uniform sampling.
It is a research artifact, not a general chat model, and requires the Jevvideo pipeline plus a Qwen3-VL-8B reader. Dev metrics are role-level sub-task accuracies, not end-to-end QA accuracy, so they should not be read as benchmark performance.
