Weaviate introduces test-time compute scaling in Search Mode via a new effort parameter, balancing accuracy and latency. On the BRIGHT Biology benchmark, ultrahigh effort lifts nDCG@10 to 57.5 compared to 13.0 with Hybrid Search. This feature, available in weaviate-agents 1.8.0, scales computation during query decomposition and reranking.
