# More Rerank Models

* **Two new reranker options**: `rerank.model` on [v3 Query](/reference/v3/query) and v2 Query now accepts `voyage-rerank-3` (alias `rerank-3`) and `gemini-3.8-flash` alongside the existing `voyage-rerank-2.5` (default) and `gemini-2.5-flash`. Voyage models are fast cross-encoders; the Gemini models are LLM rerankers with a higher quality ceiling on complex queries at higher latency — pair them with small candidate pools. The family aliases `voyage` and `gemini` keep resolving to each family's default, so existing requests are unchanged, and the response's `rerank` envelope keeps reporting the model that actually ran.
