What is multi-qa-mpnet-base-dot-v1?

OMW evidence review3 Oct 2026

Open Model Weights records multi-qa-mpnet-base-dot-v1 as a 0.109487B-parameter text embeddings open-weight model in the multi-qa-mpnet-base-dot-v1 family, with Sentence Transformers listed as the developer. The checked source repository provides 13 recognized weight artifacts, format evidence for Safetensors, PyTorch, ONNX and a verified context window of 514 tokens. Values that are not evidenced in the checked sources remain explicitly undisclosed or unknown.

The repository declares Not declared in model-card metadata. Commercial-use status requires manual review. Open Model Weights reports the checked license evidence and classification; this is not legal advice.

No base model is declared in the checked standard lineage metadata, so Open Model Weights does not infer one. In the checked repository, training or recipe evidence is present and a data-disclosure signal is present.

LINEAGE & PROVENANCE

What the checked sources disclose — and what they do not.

Open Model Weights does not infer a hidden base model or training corpus when the checked sources do not declare one.

RUNTIME SIGNALS

Compatibility claims stay attached to their evidence level.

Declared and model-card-mentioned runtimes are discovery signals. They are not treated as Open Model Weights runtime tests unless explicitly measured.
