Box expands Nvidia partnership, unveils AI workflow builder

Box unveiled Box Context Retrieval at BoxWorks 2026, a permission-aware search engine for AI agents built on Nvidia's Nemotron retrieval models, which it says can improve search accuracy 20%, cut token usage 90% and answer questions four times faster; it reaches Enterprise Advanced customers early next year. Box also introduced Box Architect, which builds agent workflows from a plain-language description and enters beta in Q4, plus new protections against bulk exfiltration and account takeover by agents.
