Orca Security worked with AWS on Discovery AI, a natural-language interface to its Sonar security graph, which covers more than 900 cloud and application resource models. The tool passes a user’s question through a schema-aware pipeline to produce valid Sonar queries, with steps for choosing relevant schemas, retrieving examples and validating the resulting filters.

AWS’s October 13 technical post says the first prototype placed the entire schema in one large prompt, using about two million input tokens per workload and taking roughly 60 seconds to respond. The production system handles thousands of queries a day at about 15 seconds per response. AWS reports reductions of 93% in token use, 90% in cost and 75% in latency compared with that initial version; these are Orca’s reported internal comparisons.
