Submitter Notes

  • Used the official SentenceTransformers 4.0.2-compatible runtime: Transformers 4.57.6, FlashAttention 2.8.3, bf16, batch size 16, and the model-card retrieval query/document prompts.
  • No retries, task reruns, or sequence-length changes; max sequence length remained 8192.
  • Standard --all result coverage: 538 tasks.

Checklist

  • Result files are committed under hakari-results/sbintuitions__sarashina-embedding-v2-1b/.
  • Result files are compressed .json.xz; no caches, DuckDB files, HTML reports, or local scratch artifacts are included.
  • The result JSON records model revision, dataset revision, runtime configuration, and package versions.
  • Overall nDCG@10 above was generated from the submitted result files.
  • Any non-default prompt, sequence length, attention implementation, candidate ranking, or reranker setting is documented above.
