The multi-qa-mpnet-base-dot-v1 model produces 768-dimensional dense vectors tuned for question-and-answer retrieval: it was trained on large question/passage pairs and uses dot-product scoring, making it a good fit for RAG and semantic search over a knowledge base. It produces 768-dimensional dense embedding vectors well suited to retrieval, semantic search, clustering and ranking.
The model handles up to 8192 tokens of input per request. Through Hormouz it is served behind an OpenAI-compatible embeddings API. Point your base URL at Hormouz, drop in a Hormouz key and send requests to /embeddings. Pricing is usage-based at $0.005 per million input tokens.
Hormouz provides stable access to the model from inside Iran, with no foreign credit card or circumvention tooling required.
The multi-qa-mpnet-base-dot-v1 embedding model transforms sentences and short paragraphs into a 768-dimensional dense vector space, generating high-quality semantic embeddings optimized for question-and-answer retrieval, semantic search, and similarity-scoring across diverse content.
