Do Not Let Models Invent Numbers - Vinoo Ganesh, Kepler

In finance, you never show a figure you can't trace. Vinoo Ganesh, CEO of Kepler (previously Palantir and Citadel), explains Kepler's architecture where models cite numbers but never write them: retrieval finds the source, deterministic code does the math, and a post-processing filter strips any figure that can't be verified. He covers the citation registry built from more than 30 million SEC documents, hybrid search and re-ranking on turbopuffer, tenant isolation, and why plain RAG produced thousands of wrong numbers in their evals.
