- Two new reranker options:
rerank.model on 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.
