Highlights

  • LoRA fine-tune of Qwen3-Embedding-0.6B over all 1,601,157 JevEmbed-Data training questions, then merged for standalone use.
  • Test-set hard-label accuracy 82.30% over 64,110 questions, up 48.51 points from the base's 33.79%.
  • Noul binary accuracy 94.38% and Choice 84.53%; Score level accuracy 69.55% with MAE down from 1.0107 to 0.4313.
  • One epoch on 16 GPUs: LoRA rank 64, alpha 32, effective batch 512, ending at adapter step 3,128.
  • 1,024-dimensional embeddings; jevembed.yaml applies a 1,024-token limit, Choice/Score temperature 0.1 and Noul slope 10.

Watch out

Apache-2.0 over Qwen3-Embedding-0.6B. The numbers are on the JevEmbed-Data test split with hard labels, BF16, fixed prompts and 1,024-token truncation, and the card notes training-data source licences vary with a source report in the dataset card. Some examples come from game cases such as Doom and Snake.
