Mixedbread Rerank
Reranks an initial set of search results with specialized models to improve relevance for complex queries.
In inglese
Mixedbread Rerank adds a second ranking stage to Mixedbread Store searches. It can use the default listwise model or a selected supported model, limit the returned results, and include selected metadata.
It is used by developers building search, retrieval-augmented generation, and knowledge-base applications through the API or CLI. Reranking is billed separately: semantic search with reranking costs $7.50 per 1,000 queries, while Toast 1 searches with reranking cost $2.50 per 1,000 queries.
Features
- Enables reranking with a boolean search option
- Uses mxbai-rerank-v3.1-listwise as the default model
- Supports listwise and pointwise reranking models
- Sets a reranking top-k limit
- Includes all or selected metadata in results
- Works through the Mixedbread Stores API
- Supports reranking from the Mixedbread CLI
Use cases
- Improve relevance for complex knowledge-base searches
- Rerank retrieved passages for retrieval-augmented generation
- Prioritize recent documents or primary sources
- Refine search results after semantic retrieval
- Search internal stores from command-line workflows
