Weaviate introduced a configurable effort parameter in its Query Agent's Search Mode, scaling test-time compute during query writing and reranking to balance accuracy against latency. On the BRIGHT Biology benchmark, the ultrahigh setting boosts nDCG@10 to 57.5, compared to 13.0 with Hybrid Search alone. The feature is available in weaviate-agents (Python/TS) versions 1.8.0 and 1.7.0.
